I purchased the King size for my bed and it has completely transformed my mattress. I feel like I am sleeping on a cloud! I can't wait to get into bed and don't want to get out of it in the morning. I have recommended this to everyone. The best purchase I have made at Sam's Club!

I purchased this topper back on 11/9 and has had nothing but aggravation dealing with the fact that it slides like crazy. However, it does provide a level of comfort to the quality of sleep that I get but when you have a problem with bulging discs, and you have to deal with adjusting the topper on a daily basis it is painful. it does have the nonslip backing but it does not work at all. Please advise.

Short of buying a new mattress this was the next best thing. Purchased for my son who moved into student housing with a really cheap "mattress" which was really just a flimsy mat with some foam inside. Great quality. A lot heavier than I expected it to be!

The new bed we purchased 6 months ago, is just right for me and to firm for the wife. We are always in Sams Club and noticed this Seta Matters Toper. We have a king size bed and purchased this one. It fit exactly right and we BOTH had a wonderful night rest. The king size was $ 179.00 and worth it. I would recommend buying.

I had this shipped to me and it arrived poorly packed in the box, which caused the box to fall apart. No packing was placed in the carton to keep the HEAVY mattress from shifting and tearing the cardboard carton. The mattress arrived with yellow stains on then ends. (I didn't unroll the mattress and look at the rest of it) There was no packaging around the entire mattress to protect it and the stains which the stains are the color of urine. The packing slip had Serta written on it but nothing else on the carton or item to verify it's Serta product. I will be returning it.

Amazing addition to any bed. This product is one of the reasons we are 5 star rated Super Host with AirBnB and Premier with VRBO. We put these on top of all of our king and queen beds, in all of our houses, in Fredericksburg and the guests absolutely love them. They constantly provide wonderful feedback about our guest ranch (legacyranchguesthouses) and the angelic comfort of our beds. Before you buy a new mattress. Try this 4" topper first. Super quick and easy to install. Works every time.

We just had a standard mattress and we couldn't afford to by a nice comfortable pillow top memory foam mattress. This memory foam mattress was in our budget. We love this product so much. My husband can now sleep better and doesn't toss and turn like before. You must get the 4inch mattress. This is the best one if you want to ensure you are so high in the air that none of your body is touching the mattress. It comes with 3 inches of memory foam and 1 inch of a seperately pillow top cover that is washable. This product is great and I recommend it to everyone.

Not long after I bought this I started waking up after a few hours of sleep and I thought it was me not sleeping well. It is hot when the temps rise in the spring and the foam is freezing in the fall and winter. This was advertised as cooling topper but I wake up hot just like I did last night and I've only had 4 hours as I sit here to make this review. Find something else, this might work for some people but I would purchase a different brand

I bought this to put on a brand new firm mattress to aid in breaking in the mattress. It is super comfortable but crazy hot. I was hoping to enjoy it more with the cooler weather but I still wake up very hot in the middle of the night. It would be 5 stars if not for the heat retention. Freeze babies will love this.

I have used Serta mattress toppers for probably 15 years. They have always been wonderful and lasted many years, until now. The new gel foam toppers are not the same and do NOT provide the support that regular memory foam does. They crush down to the surface below the topper, and if you have any kind of joint ache, will not help; in fact seems to make it worse. Don't waste your money on this.
