Hi Wideawake,
You can see the quality/durability guidelines I would suggest in post #4 here and there is more detailed information about all the variables that can affect the durability and useful life of a mattress relative to each person in post #4 here.

Roma mattress which is on sale for $495,
or
6" latex mattress at $595 - SleepEZ seems to have a very straight forward return policy.[/quote]
You can see some comments about it here but this is an all 100% natural latex mattress except for the cover which is quilted with a thin layer of polyfoam. It has a different firmness level on each side. Since it is all latex (except for a thin quilting layer) there are no weak links in the design.

Twin Solid Core Latex Mattress $595
or
Twin Eco Sleep mattress $547[/quote]
The solid core Latex mattress has 6" of blended Talalay latex and has a cotton cover quilted with wool. There are no weak links in this mattress either since latex is a very durable material.
They don’t list the materials in the Eco Sleep Mattress so I don’t know what is inside it.

which has layers and tempts me because my parents won’t be able to try out various mattresses prior to buying, and the $499 price is attractive[/quote]
This is a component mattress that uses 3 layers of synthetic latex which is also a very durable material so there are no weak links in this mattress either. As you mentioned … the layers can be rearranged inside the cover after a purchase to change the comfort/pressure relief and support/alignment of the mattress so in effect it is several mattresses in one (there are 12 possible combinations).

This has the same flexibility of the latex version and is only $289, I don’t know whether anyone has had experience with their polyfoam.[/quote]
They use 2 lb polyfoam which is also a high quality material so there are no weak links or lower quality materials in this mattress either. As you mentioned it has the same layering flexibility as the Freedom mattress but uses polyfoam instead of synthetic latex.
They also use some very high quality and durable materials in their mattresses and none of their mattresses have any weak links either.
