I think the first thing I would suggest is to read post #1 here which has a step by step process and includes links to information that can greatly improve your chances of finding the best possible quality and value mattress that is suitable for your specific needs and preferences.
A mattress is only a good as the quality of the materials that are in it and in almost all cases the weak link of a mattress is the quality of the materials used in the upper or comfort layers of the mattress not the materials in the support core (which are usually an innerspring, polyfoam, or latex). All the different types of materials that are used in mattress comfort layers have lower and higher quality versions. This includes polyfoam, memory foam, and latex (the foams that are usually used in the comfort layers). The key is to know how to tell the difference. In the case of polyfoam and memory foam … foam density is the most important part of durability and in the case of latex the type and blend of latex plays the most important role in durability. since the weak link of most mattresses is in the upper comfort layers, this is the part where knowing what is in your mattress is particularly important.
There are no “pure” memory foam mattresses because memory foam is too soft to use as a support material and is only used in the upper layers of a mattress for pressure relief. All memory foam mattresses would have either polyfoam (most common), innerspring, or latex base layers under the memory foam. If the memory foam is lower quality (under 5 lbs density) then it would generally be the weak link of the mattress and the cause of most durability issues.
So what this means is that regardless of the type of materials you prefer, durability is directly connected to the quality of the material, especially in the comfort layers, more than the type of material itself. A memory foam mattress that has an innerspring underneath it for example can still present issues if the memory foam on top is low density.
Phoenix,
I want to thank you for all the great info!
I wound up ordering the ultimate dreams latex mattress in a softness rating of 7. Hopefully the free latex pillow is included in the order.
Once I get it and i’ve slept on it a few nights i’ll come back and report my findings or write a full review.
