This is interesting...I too need to do something with my existing mattress...It is the organial foam I assume...I was looking into putting a memory foam over the top of it but before I do i was wanting to get some opennions from others that do have it....Its for the "V" bert...so here is my question...1. Do i just install a 2" memory foam overlay ? 2. Replace the existing 4" form mattress with same thickness memeory foam one.
My experience with memory foam is that even the good ones wear out in a year as well as holding bodyheat. A good foam mattress made for boats is double what you'll pay for memory foam but it doesn't hold heat and it'll last 5 years
FYI, Tempurpedic makes a new version of memory foam called "weightless". I hate memory foam because it holds heat and creates a body impression. But this new stuff is great. Doesn't hold as much heat and is fast response, so no body impression.
Back pain gone in two nights after replacing our old top of the line coil spring pillow top. One year later and this weightless mattress is still like new.
