I thought I would wait a few months before writing a review, so here it is: We really needed a new bed (ours is about 8 yrs. old), but couldn't afford to spend $1000-2000. My husband and I were waking up with sore backs every morning. I thought I would try the memory foam mattress topper first, at least to 'buy us some time'. It arrived in a rectangular box and I unfolded it and let it sit in the guest room for a day or two. Then I dragged it to our room (a bit awkward to carry, but not too bad:) and put it on our bed. We have a King size bed and it fits pretty well. I bought new deep pockets sheets at the same time and even though they don't fit all the way down to the bottom of the original mattress, we haven't had problems with them slipping off. My husband was very skeptical about the mattress topper at first, but quickly became a fan after about 2 nights. We no longer wake up with back pain. I wouldn't say it's ' like sleeping on a cloud', but it is very, very comfortable once you get used to it (after a night or 2). I have been very happy with it, especially since we don't have to buy a new bed now! I was worried about the temperature issue, but haven't noticed any problems. My husband tends to be warmer than I am and he hasn't had any issues either. I think he likes the mattress topper even more than I do! He says he sleeps better too. I have noticed that I no longer wake up several times each night to get comfortable, so that is a definite improvement. Overall, I am very happy with this mattress pad and would recommend it!
