I will say I was a little disappointed that the memory foam part of this 2 piece set was very thin, but still feels great. I wanted the feel of a memory foam bed, after two back surgeries I cant seem to find any mattress that doesn't hurt my back and memory foam is total comfort....the only saving grace for me was that I had also bought the other Slumber Solutions 4" ALL memory foam topper as well, due to the fact I wanted to make a memory foam "mattress".... the reason I bout this 5" one was because it had the "just foam" for support which is needed but the memory foam part was on the thin side. So with the 4" and this 1" I have a total of 5" of "memory foam" on top of 5" of support foam.... I will say the 2 toppers together is like sleeping on clouds, no matter how you lay on it you are in TOTAL COMFORT! It has only been one day and the smell is the only down fall, when you turn over the smell comes out, but as the other reviews has said it takes about 3 days for that to leave..I'm not worried I love what I have created for a third of what a memory foam mattress cost!!
