Hi infoquestbarnes,
That’s a lot of information but unfortunately it doesn’t include the information that you would need to assess the quality of the materials in the mattress or their durability or make meaningful comparisons with other mattresses.
For this you would need to know the thickness and density of any memory foam or polyfoam layers and the type and blend of any latex in the mattress.
I would generally avoid dealing with stores like the Brick completely (see the information, steps, and guidelines in the tutorial post here) but when I talked with Carey at the Springwall factory in Calgary (who is an engineer), he told me they would be glad to provide this information to consumers even if stores that carry their mattresses don’t provide this information to their customers (like the Brick) so you have access to the information you need even if the Brick won’t provide it.
At the very least I would want to know the density of the following layers …
2" Percell Bio Foam Upholstery
2" Plush Trizone Comfort Layer
2 Layers of 3/4" Foam (total 1.5")
If any of these layers are less than 1.8 lb density polyfoam then I would also want to know the density of the 1/2" memory foam layer and the memory foam and the polyfoam in the tri-zone convergence layer as well because I generally suggest a guideline of “no more than an inch or so” of lower quality/density or unknown density materials in a mattress to make sure there are no obvious weak links in a mattress and reduce the risk of early foam softening and breakdown.
Once there are about 2" or more of lower quality or unknown foams in the upper layers of a mattress then there is a more significant risk that the mattress will be less durable and have a much shorter useful lifetime and since foam softening and the loss of comfort and support that goes with it isn’t covered by a warranty you could end up with a mattress that fairly quickly was no longer a good match for you in terms of PPP and you would need to replace it no matter how good it felt in the showroom.
