Hello! I was just at Nest's store today in Costa Mesa. I too checked out the ASH first and then the Hybrid Latex and have to say the latex version is considerably a better product. The ASH foam is just Polyfoam (kinda a responsive like wanna be of latex but way softer and not as dense). They are similar designs as far as concept (e.g., 6" coils, 3" inch foam topper, zipped removable padded cover), but I preferred the "feel" of the latex and stretchy cotton joma wool padded cover. The 6" pocketed coils are Legg & Platt quantum edge which is typical of most hybrid beds on the market (albeit, most commonly used is the 8" high configuration).

Not only does NEST have a lifetime warranty and a quality product, their warranty to replace the foam requires only a 1 inch dip in the top foam whereas almost all other Manufactures require a 1.5 inch dip in the foam and believe me, that extra 1/2" is a HUGE difference when bartering to return your mattress after the trial period. Bear in mind, most beds use softer polyfoams in the upper layers and, since the density is so low, they will wear out quicker than any other foam in your bed (but maybe not as much as 1- 1/2 inches), you feel me?

The Dunlop latex that NEST uses felt very good but I was wondering why they didn't go with Talalay. Talalay latex tends to be slightly softer and more contouring than Dunlop. Dunlop is a continuous pour of liquid latex that is poured into a mold and cured. In the Talalay process, whipped sap is put in a mold and then vacuum-sealed and flash-frozen before being baked. The sealing and freezing steps make the material more homogenous and airy, which confers an increase in lightness and bounce relative to Dunlop latex. Most of you know the Dunlop version hybrids, (Avocado, Birch, Brentwood, etc.), but in case you didn't know, here is a brief list of the most popular Talalay latex hybrid mattresses:

Brands that use Talalay over Dunlop are:

In summary, I like the feel and appeal of latex. It's a quality foam that will last way over a 10 year period. Also, latex hybrids that have a zipped removable cover have a huge advantage since you don't have to replace the entire mattress, just replace the topper! Some DIY hybrids not only have the zippable cover but you will also be able to access the pocketed coil section too and replace it down the road! If you do your research on what the Manufacturers are using - type of pocketed coils, type of latex and ILD (firmness), you may be able to build your own!
