Bought this to replace an older memory foam mattress topper. This one is much more comfortable possibly because of the additional 1 inch mattress cover. As mentioned it does need to lay out for several days to release the chemical smell. Would recommend it to someone who like a cushiony, soft bed.

Yes, The memory foam did smell, but frankly not so much that it couldn't have gone on the bed straight out of the box. Left it unrolled to air out 2 nights--no odor issue at all. Easy to put on the bed, plenty of fabric to go under the mattress, and more importantly, very comfortable

We bought a firm mattress from Sam's a month ago. It was so firm my spouse and I were waking up with sore backs. The pillow topper has made sleeping a dream. It is so soft and warm and comfortable. We can roll and move during the night and we just melt into the foam. Worth every penny

"Serta 4" Pillow-Top and Memory Foam Mattress Topper" -- The mattress only came with a pillow top w an attached mattress cover with no foam. i waited a few days for the pillow top/foam to expand, but did not expand. returned the item.. so disappointed, plus the box was in terrible shape and took a long time to arrive.

Ridiculously AMAZING!! Slept on it for a week and then felt too guilty not buying two more for my kids!! Lol my back pain, shoulder pain is gone!! You melt into it ! I no longer toss and turn! I’m so so glad I got it! Sams did a great job , quick delivery!

Very thick and super comfy!! Love sleeping on it. Only negative for me is the mattress pad that goes over the foam is made in China (foam in USA and assembled in USA) and I couldn't see that online, only when I unpacked it. I try never to buy anything made in China-safety issues!!!

For the last 4 1/2 years I haven’t been able to sleep on my right side following shoulder replacement surgery. My bed was just too hard. When I recently started waking up with hip pain, I knew I had to do something. After reading reviews on multiple mattress toppers, I decided to give this Serta a try. What a difference! I’m sleeping on my right side & waking up without hip pain.

I was very excited to buy this mattress topper for my daughter. Her mattress was not comfortable and I didn't want to buy a new one. After I put it on the bed, I noticed strong chemical smell! (like in the other reviews) So I let it air it out in another room for about a week or so. I really didn't want to return it. The smell faded. Now my daughter says the mattress topper made a big difference. She can sleep comfortably with no aches and pains in the morning. I like that it comes with a protective cover, which helps to keep it clean and gives more comfort.

The topper slides a lot with no way to hold it in place. I find my self rearranging it very often. The first night I used it I woke up with back pain but after a few nights my body got used to the topper. It is very cool but it would be nice if it had straps to hold it in place. Not horrible for the price though but I don’t think I would buy again.

We bought an extremely expensive mattress set about a year ago....a name that everyone would recognize. After trying for two months to get used to it, our time ran out to return it, and we were stuck with it.....way too firm for us. Our sleep was never comfortable like this mattress company advertised, and in desperation to find something to help before we made another mattress purchase, I tried this topper. What a wonderful difference. Just the right amount of "give", and from the first night we used it, we noticed that we were sleeping so much better. We actually look forward to getting into bed at night, something we kind of dreaded before. Our firm mattress makes a great base for this topper. I would definitely recommend this to anyone who is looking for an inexpensive (comparatively) way to improve the comfort of a mattress they're not happy with.
