Hi Rockfamily,
Here is the layering of the Talora from top to botton and my comments …
3.3-cm (1.3-in.) firm EcoFoam uses Natural Foam Technology to offer enhanced comfort, support, conformability and durability:
This is polyfoam used in the quilting and it’s around the thickness range I would consider to be OK. (@ 1")
1.3-cm (0.5-in.) 5-zone ObusForme® Ergo Layer™ - 5 alternating cushioning layers of resilient natural latex and memory foam:
This is a very thin zoning layer. The latex is good and it is also thin enough that I wouldn’t worry too much about the density of the memory foam. It makes the total layers subject to softening a little thicker (added to the quilting layers) but it would still be OK IMO because softening of the memory foam in the zoning layer won’t likely be an issue (it’s meant to be soft anyway just like the quilting layer).
7.6-cm (3-in.) ObusForme® latex responds to your body and is extremely breathable, allowing for a more comfortable night’s sleep:
This is probably a good quality material but I would want to know the type of latex (Dunlop or Talalay and whether it was natural or blended).
17.8-cm (7-in.) soy-based foam core provides superior support and resilience:
This is the polyfoam support layer and i would want to know the density of the polyfoam. Hopefully it will be 1.8 lb or more.
Once these questions are answered then it would be possible to make some kind of assessment about “value”.
Overall though … it has a reasonable amount of foam that would be subject to softening (1.8" including the memory foam in the zoned layer) which isn’t too bad and with layers this thin and that are meant to be soft anyway … then foam softening isn’t as much of an issue.
If the base foam and the latex are both good quality … then it would be reasonable value IMO.
Of course there is no way with a Costco purchase to know if the mattress is suitable for PPP (Pressure relief, Posture and alignment, and Personal Preferences) but with the return policy of Costco some people are OK with the risk of buying a mattress where there is no way to know how well it may work … and at least with a latex comfort layer the risk of foam softening is less (assuming the unknown layers are OK) so there is less chance of having a problem in a couple of years when you can’t return it any more.
The Dandelion top to bottom and my comments …
3.8 cm (1.5 in.) Supersoft™ StayTrue™ convoluted foam
1.3 cm (0.5 in.) Supersoft™ StayTrue™ foam
This one is not starting off too well because there is already too much soft polyfoam on top. I would definitely want to know the foam density of these layers … especially since there is even more polyfoam underneath them.
2.5-cm (1-in.) latex foam
5.1-cm (2-in.) StayTrue™ soy based foam ;
5.1-cm (2-in.) Supersoft™ StayTrue™ soy based foam Base layer:
2.5-cm (1-in.) StayTrue™ foam
One inch of latex but then there is 5 more inches of polyfoam. Again it would be essential to know the density to make sure that you don’t have a total of &’ of polyfoam subject to softening.
15.2 cm (6-in.) Smart Latex® foam core
This is synthetic latex and is the lowest cost/quality of latex available. While it probably won’t be an issue with softening because it is under 7" of foam … it certainly isn’t the highest quality of latex available.
I would be very very skeptical of this mattress especially considering the thick layers of what is almost certainly lower quality polyfoam in the most important upper layers of the mattress and also because it’s not very likely that anyone will tell you the density information you would need to know. I would avoid this one completely regardless of any return policy.
