This is 4 Stars instead of 5 only because it took nearly 2 weeks to get the odor out of the topper. Finally clear and very comfortable - a much needed improvement over our aging mattress.

I bought this to help with an old mattress to become more firm, it doesn’t but if my old mattress were good it would make it very soft and comfortable

My wife and I bought a mattress a few years ago and we were having trouble sleeping due to its firmness. We added the topper and have been sleeping well since. We like it so much we even bought one for our travel trailer.

Bought this for my son for his dorm. His mattress was so uncomfortable with no support. He is now loving it with the gel pad and sleeping like a baby. This was worth every penny spend!

Mattress topper is comfy and affordable. However it definitely shifts which is very frustrating. Despite seeing that it’s anti-slip it definitely slips and we did not have this problem with our previous mattress topper.

Great 4 inch topper for my king memory foam mattress. Makes it softer which is exactly what I wanted. Perfect for me. I love the cover which keeps the topper clean and is soft as well. I definitely recommend this topper.

My body literally sank into the foam cushion as if it was conforming to my body! I normally toss all night, I have been waking up in the same position as when I passed out. (On my back) Great quality, Great comfort, Worth every cent!

What the Serta 4" Pillow-Top Memory Foam Mattress Topper covered was a firm mattress that was getting lumpy. The Serta 4" Topper is wonderful. It is so comfortable and our sleeping time has improved.

Super way to refresh an older twin mattress. The cover is excellent, and ties the topper to the mattress very well. It does have the typical foam odor, but that is gradually fading. Will buy again for another bed.

was surprised how supportive this was. was worried would be too soft. it is soft...it feels like laying on a cloud or marshmellow, but really does support my back. we had one before this that did not and hurt my back
