I recently moved apartments and adopted a bed . . . a really, really firm bed. I'm a stomach sleeper, so this didn't work for me. After a friend pointed this deal out to me, I read the reviews and placed my order. Since receiving the topper, I have slept really well. This was a perfect solution to my ultra hard mattress. Now when I get into bed, I don't move an inch, no matter what position I'm in. Also, the mattress has relieved some circulatory issues for me; I used to wake up with numb limbs. I have a full size bed and ordered a queen. It's a little too big and runs over the edge of my mattress, but I didn't bother to cut it down. I put a mattress pad and fitted sheet over it and it works just fine. I'm not sure if getting a 4 inch topper is worth it, but you can't beat the price on this 2 inch topper. Plus, the pillows are an awesome bonus. No issues with smell or rips.
