Thinking of buying this Black Friday mattress without testing first...

Hi bigfootnels,

Yes … it’s exactly the same thing with mattresses and as with furniture I would look for a minimum of 1.8 lb density for polyfoam except for perhaps an inch or so of lower quality foams in the quilting layers which won’t have a significant effect on the useful life of the mattress. With memory foam I would kook for a minimum of 4 lb density. Higher densities are more durable because the density of polyfoam or memory foam is the single biggest factor in its durability. There is more about the many factors that can affect the durability and useful life of a mattress in post #2 here.

Most cities have several foam shops where you can order many different types and densities of foam. I don’t keep a list of them like I do with mattress manufacturers so I don’t know of any specifically in the Philadelphia area (a google search will bring up a few) and there are some online foam suppliers (polyfoam, memory foam, and latex) listed in post #4 here.
