Great product. This is the second one that I bought. There is no horrible smell, it is not only comfortable and cool but two years later the original one I bought still feels brand new! You won’t go wrong purchasing this product!
3 in of foam and toss the fiber topper away before you ruin your clothes, carpet and mattress... it will literally deteriorate after some time.
Worth only $100 IMHO. Took this for a spin and after trying to make it work we said forget it and went back to using our mattress w/out it.
Kept the foam for when guests stay over but would've rather saved our $$$ and looked somewhere else.
The ad states it is a 4.5" total thickness. 3" of memory foam and 1.5" fiber topper. they got the 3" foam thickness correct, but I think they meant to say .5" fiber topper thickness. So, I'd call this a 3.5" total thickness.
