This mattress is much firmer than expected and not comfortable. There are two sides to the mattress (not made terribly obvious in the product description) one firmer and one softer but I found them both to be very uncomfortable. I read through the reviews prior to buying this, and with so many glowing accounts I mentally dismissed the few critical ones, but now find myself completely agreeing with the dissenters. The mattress is (1) much firmer than I expected and (2) not comfortable even to one who likes a firm mattress (my husband does and he also can not sleep on this). On a positive note I will say I had no issues with smell or the edges being somehow softer. But we can't sleep on this. Waiting to hear from Wayfair if there is any way to return this, but I certainly can't box it back up so am worried I'm stuck with it.
