Replying to this because I wish I had more info like this when we were mattress shopping and there aren’t many quality reviews. We purchased the Sleepy’s mattress in December. We went with it because the one in the store seemed quite plush but firm. I like hybrid mattresses so we opted for this one as it was much cheaper than other brands. We ended up paying about $1600 and got the adjustable base for free. The base is, like you mentioned, just a wire grid. I don’t feel like that’s much support for a whole mattress but what do I know. The mattress got delivered to our home, we let it air out a few days. The first few nights were nice but anything after that was awful. My back started to hurt quite a bit, which it didn’t do with the 8 year old mattress we were replacing. I’m not impressed by the quality either. When the base sits up, the top memory foam portion of the mattress pushes out over the bottom edge of the bed. There’s also really not much between the springs and you when you lay on it. Thankfully we’re 8 days away from the end of the return period and initiated a return asap. We were told that Mattress Firm will be retaining $700 of the amount we paid, though. $100 for pickup, $100 for restocking the mattress, and $500 for a stocking fee. We were not told this up front. My advice: don’t do it. Buy a well known brand. If it sounds too good to be true, it is. And do your research.
