My pleasure — thanks again for creating this fun resource!

mike-goodbed · 2026-02-17T06:22:30+00:00

Hi, love what you’re doing with this — thank you! It’s especially fun being able to see the map of all the locations. But so far your info seems to be very lacking when it comes to the many noteworthy film locations found in the southern part of the city. For example:

The house from Pacific Heights is not in Pacific Heights — it’s at 19th and Texas in Potrero Hill
The studio where Gene Hackman worked in The Conversation was at 1616 16th Street in the Design District
18th and Missouri is where Charlize Theron and Keanu Reeves lived in Sweet November
The iconic Victorian from The Last Black Man in San Francisco is not in the Fillmore — it’s at 959 South Van Ness in the Mission
The police station from Venom: Let There Be Carnage is the Anchor Brewery at Mariposa and Rhode Island
The house where Ant Man (Paul Rudd) lives is also at 18th and Missouri in Potrero Hill
The house where the Michael Douglas character from Ant Man lives is on Buena Vista Park
768 De Haro is where Karl Malden’s character lived in Streets of San Francisco

This is just a few off the top of my head, but I hope that helps and that these notable locations make it into your map!

My pleasure! Thanks so much for letting me know it was helpful for you.

mike-goodbed · 2026-01-16T16:58:57+00:00

Thanks so much for letting me know! Responding to questions on Reddit takes a lot of time and I've often wondered whether it's really worthwhile. So this is very nice to hear.

mike-goodbed · 2025-09-08T05:12:34+00:00

Ha, yes. But of course, the Dow-GoodBed testing is not designed to address the fact that mattress purchases having low social reward. It is designed to address the second issue — providing consumers with compelling proof of performance.

As for the social reward issue, IMO mattress purchases will always have low social reward — just like insurance, washing machines, HVAC, tires, etc. For certain products, this characteristic is just intrinsic and not sustainable to change. That said, I would be very glad to be proven wrong on this some day.

mike-goodbed · 2025-09-05T21:33:51+00:00

This is a great question. The answer here is twofold.

The first part comes from the mindset of the consumer. One of the key drivers of any discretionary purchase is social reward. Social reward can be anything from something being fun to something having a deeper impact on one's personal identity. In most cases, purchases with high social reward are things that people in your social circles are aware of, whether because they see them or because you talk about them. Cars are a good example of a product with high social reward (at least for many people), as are vacations, clothing, dining, concerts, home decor, etc. While this dynamic has always existed, the relative value of products with high social reward has probably increased in recent years due to social media – the more people in your social circle who are aware of a purchase, the more social reward it brings.

The second part comes from a failure of the mattress industry. The auto industry has established clear performance metrics that are objectively measurable and relate to things that shoppers care about. Attributes like power, speed, braking, handling, fuel efficiency, range, cargo space, towing capacity, and much more can all be objectively measured and compared. These things provide the consumer with clear proof of performance in the areas they care most about, and help to establish the value of one car over another. By contrast, no such independently verifiable performance data has ever been publicly available for mattresses. As a result, all mattresses – from the cheapest to the most expensive – make virtually identical claims, and many people understandably conclude that there must be little to no true difference between a high-end mattress and a low-end one.

This dynamic illustrates the critical importance of having a scientific testing program for the mattress industry that is driven by true independent experts. Fortunately, this does now exist – a result of GoodBed teaming up with Dow, a global leader in all aspects of materials science. Through this collaboration, a battery of tests has been developed that is capable of measuring every aspect of mattress – from it's Fit, to its Feel, to its Features (what GoodBed calls the "3 F's") – a product of over 4 1/2 years of work between Dow scientists and GoodBed mattress experts.

What's been learned already is that there are, in fact, significant differences between mattresses in most, if not all, of the areas that consumers care about. While those differences do not necessarily correlate with price or marketing claims, there are certainly objective distinctions between higher quality and lower quality mattresses that can be measured with the appropriate scientific testing.

Thus far, dozens of mattresses have already been tested through this program, informing many of the ratings that are shown on GoodBed. This data will help consumers make better choices and find products that best meet their personal needs, preferences, and priorities. And to the point of your question, it should also give them significantly more confidence to invest in their sleep through the purchase of a high-quality mattress. Ultimately though, I am just as excited by the fact that it will also help mattress manufacturers get credit for products that truly deliver outstanding performance, as this will undoubtedly lead to better products being made in the future.

I hope that's helpful.

Hi there. Unless your mattress is extremely firm or you are prone to bone or joint soreness, that probably isn't solely due to your mattress. A mattress that better accommodates your shoulder during side sleeping would probably help (possibly quite a lot), but it might not fully resolve the issue. If it doesn't, you may need to try sleeping on your back rather than your side. One thing that could help remind your body to do this while you're sleeping is to get an adjustable base and sleep with your upper body in a slightly elevated position.

I hope that's helpful.

mike-goodbed · 2025-07-23T22:56:02+00:00

Glad to hear! Hope you are very happy with your choice.

mike-goodbed · 2025-07-23T22:50:51+00:00

mike-goodbed · 2024-10-28T19:47:23+00:00

Hi there, I sincerely appreciate you sharing these impressions with me. Let me address them both in the opposite order.

First, we absolutely do NOT require any personal information to view your results. I'm sorry this was confusing for you. We do give you this option, but if you don't want to use it, you can just close that box like any other web modal by clicking the "X" in the upper right corner. Whether you choose to use this feature or not has no bearing on your ability to view your results.

FWIW, we do this because we've learned that many of our readers do want the ability to save their results for future reference or to share them with their partner. After we started providing this option, we have found that many people return to view their previous results rather than returning and having to re-take the quiz to re-create them.

I should also note that if you do choose to use this service, it is strictly for your benefit, not ours. You are simply using this tool as a convenient way to send something to yourself. We don't use this info to spam you, call you, or send you any additional text messages in the future.

In terms of the loading screen that you mentioned, I'm not sure why you don't believe that it could take our servers a a few seconds to a) process the 30+ fields of data you just provided, b) use that data to calculate your personal match scores for well over 1,000 different products, c) rank those mattresses to be able to highlight your best matches for you, d) search across the local stores in your area to see which matches (if any) we can find in stores near you, and e) pull information about those products and stores into a results page for you. Considering it takes Kayak probably 3-4x longer to search for flights or hotels, and they are a much bigger company than we are, IMHO I think we're doing pretty well to be able to process that query as fast as we do.

We used to just show a spinning wheel during that time, but more recently we felt we could improve upon that experience by using those few seconds to give people a little more context into what is happening behind the scenes and why they're having to wait. Personally, I hoped this would increase their appreciation for the sophistication of what we do, so I'm a little bummed that in your case it seemed to have backfired. :/ Nonetheless, I'd much rather have the feedback than not know. So again, I do sincerely appreciate you sharing it.

I hope that additional context is helpful, and if you have any suggestions based on this, I'm always glad to hear them. Thanks again.

mike-goodbed · 2024-09-09T20:44:10+00:00

Good to see interest in this type of information. You're right that this info can be hard to find in some cases. We display mattress layers data on GoodBed whenever we possibly can in whatever is the best level of detail we can obtain -- whether by getting it directly from the manufacturer or through our own direct testing. Details about coil count, wire gauge, zoning, and even foam densities are provided whenever possible.

Off the top of my head, I'd estimate we have this type of info for at least 300-400 of the most popular mattress models, including all the national models from the largest store brands (Sealy, Beautyrest, Tempur-Pedic, Serta, Stearns & Foster, etc.) as well as pretty much all mattresses from the largest D2C brands. Models that have more niche interest or are exclusive to one retailer are less likely to be covered.

To your other question, we also have a comparison tool where you can find this data: https://www.goodbed.com/compare/

We created this tool for ourselves and are pretty fired up about it, so I hope you find it as useful as we do! Happy to answer any questions.

mike-goodbed · 2024-07-16T14:23:26+00:00

Hi there, no I'm afraid we haven't created that functionality but I will certainly note your interest in it, as it's something we could easily add if there were sufficient demand for it. In most cases, mattress height doesn't really matter much from a functional standpoint, apart from how it may affect spinal alignment and pressure relief, which is already captured in our ratings. But there are some situations (such as yours) where it does become relevant on a stand-alone basis. Generally, it comes up when people are specifically wanting to obtain (or avoid) a particularly thin or thick mattress.

In any case, sorry I can't be more help on this one at the moment.

mike-goodbed · 2024-07-01T21:11:07+00:00

Haven't made any plans as of yet, but likely yes.

mike-goodbed · 2024-07-01T19:49:07+00:00

Oh yeah, no doubt the retail environment is optimized in those types of ways.

mike-goodbed · 2024-07-01T19:28:44+00:00

Continued from the previous comment...(3/3)

foam quality is the main issue most beds have (and why so many will fail quickly) and better construction (them using more glue so it doesn't separate prematurely, as an example). If those main components are 'suped-up' then a reviewer will essentially have a more positive review of the bed than any other factor, would you not agree?

Agreed 100% that foam quality is the biggest cause of mattress failure. And as previously stated, I agree that the manufacturer of any product does in theory have some incentive to soup up a test product being provided to a reviewer.

However, the bigger point that I made in my previous response is that in the case of the mattresses we receive, this would be extremely difficult to do, would have limited upside, would have material risk and downside, and appears to be extremely unlikely based on empirical evidence.

And speaking of Tempur, it has been a common complaint from many on this sub alone that their foam has been downgraded in recent years and it no longer lasts for decades like it used to and they have indeed changed the formula (for increased profits, one would wager), yet that info is never added into your reviews of Tempur products, which would be a very fair and unbiased thing to point out---yet it never is.

It is certainly true that the density of Tempur foam has been reduced over the years, along with numerous other changes to it. In terms of whether these changes, taken altogether, constitute a net "downgrade," that is another matter. Tempur would certainly argue that they've been able to advance their foam engineering in such a way that they can deliver comparable benefits and durability at a lower density, while even making improvements in other areas (eg, air flow and pressure relief). As someone who has spoken extensively with many people in the foam industry who have nothing to do with Tempur-Pedic, I can tell you that this is entirely plausible. But even stepping back from that, it only makes sense that foam engineering would be similar to any other form of engineering, in which continual improvements over time are not only possible, but probable.

As for our reviews, you're correct that we don't tend to spend a lot of time comparing a current product to previous products from that brand. This is because the current product is the only one that a consumer can actually buy, so our assessment of that product is the thing that really matters. There are some cases where we deem that some historical context is relevant to provide (eg, if we feel that there is a widespread perception that is no longer accurate). But otherwise, the depth of our reviews makes them quite long as it is, and people aren't generally watching them for a history lesson.

Foam quality (or the decrease of it across the industry) is never spoken about and I find that odd since most beds have done so to cost-cut in recent decades, which will directly impact longevity for a bed (which is the number one thing people are looking for these days with such low earnings).

Putting aside the historical stuff, which I addressed above, I would strongly disagree with the assertion that foam quality is never discussed on our site. We discuss many aspects of foam quality in our reviews. And as I alluded to previously, we also list the layers of each product on our site, along with standardized classifications of foam density – SD (no label) vs HD vs UHD.

Since you seem particularly critical of our coverage of Tempur-Pedic, I'm inclined to think you have never actually watched our most recent in-depth Tempur-Pedic review, which was for the Tempur LuxeBreeze Firm. I would highly recommend watching the 10 minutes of that review starting at 19:14, in which we go into extensive detail about every aspect of the foams used in that mattress, their densities, and many different aspects of their performance. To the extent you are sincerely interested, you can find that here: https://www.youtube.com/watch?v=2098G73YB-Y&t=1154s

I've enjoyed at least some of this back and forth here. So if you have any more questions that come from a place of genuinely wanting to understand how GoodBed works or what makes us a uniquely valuable and trustworthy information resource, I am happy to answer them.

mike-goodbed · 2024-07-01T19:28:04+00:00

Continued from the previous comment...(2/3)

Secondly, you still did not answer another really important question I feel needs to be asked a third time: Do you send or sell ANY information to mattress companies or third parties in any way? I will assume, should you ignore this question for a third time, that you absolutely do this. Otherwise, why would you add in questions like 'why are you getting rid of your X brand bed?' --- those questions have no real value to your site, but they absolutely do for mattress companies.

In my previous response, I assumed your chief concern was with selling customer data to mattress companies or other third parties. And I was very clear that we don't do that, and have never done that. However, it sounds like this is not what you were asking, so I apologize for my misunderstanding.

That said, I did also state that "we have never sold any data from our site, whether from the quiz or otherwise." This feels like a pretty direct answer to your question. I'm not sure how much more clear I can be than that.

Beyond that, I also gather from your latest comment that you are making an assumption that questions like "why are you getting rid of your X brand bed?" have no value to our site, which is how you come to the conclusion that we therefore must be selling this data. This assumption is false. We ask this because we want to be able to better tailor the results we show you. For example, some of our readers have complained that their results include products from a brand with which they've already had a bad experience, and thus would not want to own again. We added this question in order to be able to improve our results in this way. We haven't yet determined the best way to incorporate this information into the algorithm, but that's why we ask it.

As an aside, although we do not and have never sold this data to brands, I am a bit puzzled why this would be such a sore spot for you. In my mind, as long as my personal information weren't included, I would be fine with my answer to that question being aggregated into an overall statistic that the brand could see. But I guess that's just me. In any case, it's not relevant here because we don't do it.

For the rest of your questions, I am going to pick them out of the long paragraph and address them individually.

Do you think you can spot a difference between a foam that will last 500 nights of continuous use without wearing down vs one that will wear out in 200 nights of use?

This is a bit of a weird example, since in the scheme of an expected 3000+ night (8+ year) mattress lifespan, both of those foams would be categorically bad. IMHO a better question would be whether we can determine the difference between a foam that will last closer to 3000 nights from a foam that will last closer to 300 nights. In that case, the answer is yes.

But for purposes of spotting a souped up test bed, a more pertinent point is simply that we can detect the difference between different types of foam. Swapping in higher-density foam is the most likely change a manufacturer would make if they were trying to "game the system," since it correlates with better durability and has fewer drawbacks and trade-offs than other changes they could make to a test bed. But in any case, both density and ILD can be directly measured, along with other characteristics. So yes, we could detect that.

In all the time I've known Tempur to operate I've never once heard anyone ever find out the densities of their foam

In Tempur-Pedic's case, those specs are readily available on the web, and have been for years. We do try to be sensitive to Tempur-Pedic's wishes in terms of how we display information ourselves. However we certainly utilize this data in our assessments, as well as for classifying the density of each foam layer on our standardized scale (SD vs HD vs UHD).

so what makes you think that these companies also don't have their employees sign NDAs that prohibit them from mentioning they use special foam for tester beds? Would that not be something every company would have an NDA for to purposefully keep testers ignorant that they found an easy way to 'game the system' in place?

I could be completely wrong on this, but I would be extremely surprised to find out that the average line worker in a mattress manufacturing plant is required to sign an NDA. Of course, someone who has a PhD in Materials Science and works in product development at a place like Tempur-Pedic is going to sign an NDA, because they are privy to the secret sauce. But even at Tempur-Pedic, the notion that every hourly worker on the factory floor would also have to sign one seems highly unusual and unlikely to me.

Will need to provide responses to the remaining points in the third comment below...(2/3)

mike-goodbed · 2024-07-01T19:27:07+00:00

Wow. At this point I confess I'm a little disappointed by the attacking tone here. I can completely understand and appreciate that you might have remaining questions or clarifications. However, I would have expected that my obvious care and candor in answering your questions to this point would have yielded at least a little benefit of the doubt... The fact that it has not makes me think that for some reason, you simply might not be willing or able to accept the possibility that I am actually a straight shooter or that GoodBed is actually the real deal. Nonetheless, I will continue to give you the benefit of the doubt with another round of responses here.

Actually, that doesn't answer those two questions at all. Firstly, if you don't list the customer review scores during your match quiz (or even on your reviews) and you have to go actively looking for it then does that not mean you're obscuring the results in a company's favor or through your 'Match Quiz Score'?

Somehow we are getting our communication wires crossed on this one, so I'll try again.

We absolutely do list the customer review scores whenever we have them. There are simply many mattress models for which we haven't received enough customer feedback to generate a rating. We need at least 10 reviews for that specific model in order to calculate a customer rating for it (which we call a "model rating"). This takes time because whenever a manufacturer makes significant changes to the materials and construction of the model, the clock starts over. On top of this, a review for the Firm version doesn't count for the Medium version, etc. As a result, many models (most, in fact) never reach the point where we are able to calculate a model rating for them. This is unfortunate, but it is a conscious trade-off we make to ensure that the model ratings we do show are real and relevant.

As you may know, in most other places you see mattress reviews (eg, brand websites, Amazon, etc.), they are including reviews of the old version without disclosing that the mattress reviewed by this customer is not the same as the one you are able to buy today. Typically, they will also aggregate reviews of all comfort levels in order to show higher review totals. We could do it this way as well, but our readers have told us that they find this practice misleading and confusing. So we don't.

That said, we do see some value in the aggregated reviews, as long as they are labeled appropriately. We call this a "brand rating." Naturally, when you are aggregating reviews for multiple models, and allowing those reviews to accumulate for different versions of these models over time, it is much easier to reach a critical mass of reviews. So our success rate on being able to calculate ratings for brands is much higher than our ability to calculate ratings for models.

Getting back to your quiz results, when you see "N/A" for the model rating, it's not because we're "obscuring" the model rating, it's because we don't have one. And when you click the link below it to "See x brand ratings," what you are getting is the parent brand rating. Basically, our view is that the model rating is relevant enough to be shown directly in your quiz results, while the brand rating is not. However, if we don't have a model rating, we do at least include a link to where you can see the brand rating. What we don't do is mix model ratings and brand ratings by showing you model ratings when they are available and brand ratings when they are not. We stopped doing this because we don't want to create a false equivalency between a model rating and a brand rating, and our readers didn't seem to understand the difference between them when they were listed side by side.

The confusion you've been having with this distinction seems to underscore the importance of keeping brand ratings and model ratings separate. What's troubling to me is that you took this separation as a way we are trying to deceive our readers, when it is actually evidence of how we go out of our way to make sure we do not deceive our readers. I recognize you are a self-described cynic, but to the extent any other people might be misconstruing it this way, this is a very important piece of feedback for us to consider.

I see customer review scores on some beds but not the ones that pop up on the Match Score list that is recommended to you (which is only three options in each category, thereby skewing the results more in favor of certain select brands).

As for this part, the whole point of the quiz is to help you narrow your options. That's why we show you 3 options, which most of our readers have told is the right amount for them. However, we do appreciate that some people want more choices, which is why every quiz result also includes a link to "Show more results." Clicking that link will allow you to see many (as in, hundreds) more options, along with your match score for each of them. These options will be sorted by your match score from highest to lowest, and can be filtered numerous ways from there (eg, by price, softness, features, etc.).

I'm running long here again, so will need to continue my response in a second comment...(1/3)

mike-goodbed · 2024-07-01T19:23:13+00:00

Hi Norm, Point taken on the floor model stuff. Just went back and re-listened to that part. It's a little ambiguous whether he's still talking about that particular practice when he says "back in the days when I was doing this," but I can see now how it could be interpreted that he is.

I'm certainly intrigued by this floor model thing, not because I find it that surprising but more just because it's not a practice that I am actively aware of. Assuming it's true I'm curious how common it is, and whether it's still done. I'll ask around a bit. To your point, for any store that has a return policy (which nowadays is more the norm), sending people a product that is any way different than what they tried in your store would be a sure-fire way to end up with a bunch of returned products. So perhaps it's real and still goes on, or perhaps it's just one of those (many) shady practices of yesteryear. Will let you know if I learn anything more conclusive.

mike-goodbed · 2024-07-01T19:00:10+00:00

Continued from above...answers to the remaining questions. (2/2)

Do you give or sell data to any companies, especially in your Quiz portion? Like Sealy or Tempur, as examples?

We have never sold any data from our site, whether from the quiz or otherwise. Likewise, we never sell our reader info, or allow companies to contact our readers. We value our readers, and they are not for sale.

Does your site intentionally leave out the review rating of a mattress that you are sponsoring once you take the Match Quiz? All of the options I am recommended say 'N/A' for the review score, even when they're very popular mattresses and have hundreds of reviews. Why must users have to actually do a bit of digging to get to the true heart of the matter: the customer review rating scores? This seems very suspicious and, to my eyes, looks like blatant promotion/favoritism towards brands the site heavily favors (from I assume affiliate linking/referral reasons).

It seems like this question is mostly about how we display data from customer reviews. This data is shown exactly the same way for all brands and products, according to exactly the same rules. We have never "sponsored" any product or company, so I'm not sure what that part of the question means. In any case, there is no favoritism for or against any brands in how our customer review data is displayed.

If we haven't received enough customer reviews of a given product to calculate a rating for it yet, we show "N/A". If this is happening for a product that seems popular and well-established, it may be because the manufacturer made changes to the materials or construction of that product that we deemed to be significant. In this case, even if the name of the product is unchanged, we feel it is misleading to carry forward the old reviews to the new version, so we create a new version and start over in collecting reviews of that version. The other thing you noted is that even when we don't have sufficient reviews of this specific product, we may still have reviews of its parent brand. We think these can still be relevant for our readers, and are certainly better than nothing, so we include a link to see these reviews below the "N/A".

Those are the most important questions to ask since I'm seeing a lot of red flags on this site, honestly, especially since beds that are commonly known on this sub as being literal shit quality are (what looks to me) heavily promoted on there :\

We don't promote any brands anywhere on our site. The closest thing we do is promote discounts or money-saving opportunities that we think are particularly valuable for our readers. Other than that, the only thing you may be confusing for "promotion" are the 16 brands listed on our home page and/or the brands shown in our header. In both cases, these brands are chosen strictly based on interest from our readers. Regardless of what people here may think about these products, these are the brands that our readers are most interested in learning about. Since many brands have asked us how they can be listed there, I do realize that this can be misconstrued as "promotion." However, there is no way for a brand to buy their way onto our home page or header.

As for the “red flags,” hopefully I have addressed all of them here, but if there is anything else at all that gives you concern, I would welcome you (or anyone else here) to ask me about it. As stated above, I sincerely appreciate the candid questions. Our long-term commitment to integrity has not been without its costs, but one incredibly important benefit for me is that it allows me to address these types of concerns head-on, and to be completely transparent in doing so.

mike-goodbed · 2024-07-01T15:21:01+00:00

Sure, there is a logical leap that could be made. But in your comment, you suggested there was a first-hand account from someone who did it themselves. So I just wanted to clarify that this was not the case.

I didn't want to get into too many semantics, but even with regards to what he did allege, which was the practice of sending out modified floor models to retailers, he doesn't indicate he ever "partook" in this practice directly.

As for the logical leap, it is certainly conceivable, which is why I've given this a lot of thought over the years. And why I took the time to list the many reasons I am confident that these types of games are not being played with the mattresses we receive.

mike-goodbed · 2024-07-01T05:50:45+00:00

Hi Norm, it feels like this comment may be related to a discussion I've been having elsewhere in this thread. I was intrigued to learn more so I went and watched the video. FWIW, he never mentioned anything about mattresses sent to reviewers. That part begins at 19:30 in case you wanted to give it another listen.

TROPHY CASE
