I purchased this after buying my adjustable bed from sams club it’s a king that uses 2 twin xl mattress.. I read the reviews before buying and read the question does this topper work on adjustable beds manufacturers replied that it does so I bought 2... ugh every morning I have to strip my bed to put it back on the mattress it slips off my bed leaving it hanging off the side of my bed.. I almost slipped off my bed when getting up during the night to use bathroom ..also when adjusting my bed at night to watch tv this mattress pad slips down and messes up the sheets! I even gave the zippered mattress cover on it .. also tried adding another mattress pad cover to help secure it .. nope epic fail! So no it does not work well with a king with 2 twin xl mattresses adjustable beds ... not sure if I can return ... but will give it a try ..

Bought the twin XL for my daughter’s dorm room. She said it’s so comfortable. The mattress topper that comes with it is not waterproof so I bought another waterproof mattress pad to make sure the memory foam was protected, then put the mattress topper over both. A little extra protection, may not be needed if you don’t care about protecting the memory foam, but the pockets on the topper were deep and covered everything no problem.

I’m hoping Serta sees this review and makes the team that designed this product sleep on it. We owned the earlier design of this topper that we loved. That version’s 1 inch part was like a fitted sheet that held the 3 inch foam firmly in place. This absolute poor design has the foam enveloped in what reminds me of a big pillow case with a zipper. We have to readjust this thing every morning and it is a major headache. DO NOT PURCHASE unless you want to pay for disappointment.

We have had this exact mattress pad for our King bed for at least 5 years, and it's wonderful! So, I ordered one for our nephew who's off to college. After we got the outer sleeve washed and ready to put on the foam part, we discovered that the foam was very discolored - it didn't smell but it was very dark yellow along the edges. YUCK! Sam's customer service told me I had to reach out to Serta; however, when I objected and reminded them that this is not a mattress, they gave me a return authorization and are sending me a label. Question is...how in the world do I get this thing back in the box? And now I have to start at square one to find another mattress topper QUICK!!

We have used this for a month now and although it adds a lot of height, and I have to buy all new sheets, I do like it. It does feel as if it is crushing more in the middle and on the side my boyfriend sleeps. I will be measuring crush depth soon. Customer service is easily accessible and promote with replies. The mattress pad included is nice but not as padded as I expected.

We just bought a new firm mattress from Sealy. While we wanted a firm mattress we felt this one was a bit harder than expected so we purchased a 4 inch memory foam topper. It is comfortable, i guess, definitely softens the feel but we both think that sometimes it feels too warm and we wind up kicking off the covers. Also the thickness of the topper makes it difficult to keep sheets in place even though the sheets are deep pocket sheets. If I was able to roll this thing back up and squeeze it back into the box, I would probably return it. Given our lack of enthusiastic response to the topper and knowing what I know now, i wouldn't have bought it.

About 6months ago we upgraded our queen size bed to a king… Due to the new bed being a little firmer than I like, I decided to purchase a mattress topper… After researching toppers, reading through multiple reviews, and loving my previous Serta topper I decided to purchase this Topper at our local Sam’s… 1) the topper does not stay in place and has to be readjusted every morning… 2)something in the material makes it extremely hot to sleep on. For example if your back is on the topper, your back will be sweating while your front will be cool. 3) If someone else is in the bed (husband or child) it causes you to roll towards the heaviest person.

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.

King size.. I opened this about 12 hours ago. It was smashed so flat in the box it has only expanded in less than 1/3 of the topper. The other areas are hard and completely smashed. I have bought whole mattresses that were in a box and never had an issue. This will be returned for sure, it was packed so tight it has ruined the foam.

I don’t usually write reviews, but this pillow top is just what my body needed to help help my aching body. I ordered a Lulaa bed in a box with firm on one side and soft on the other as it’s flippable! It was only two weeks and my shoulders and hips were hurting so badly. When I put this on within a few days my pressure points in hips, shoulders and my neck felt so much relief. It is noisy with the cover but it’s so worth it. Mine sets directly on my mattress and it creates about 15” high as the top layer doesn’t make one inch. The skid bottom stays in place on my bed and then I put my deep pocket sheet on it and I am so pleased. I thought I would have to return the mattress I bought here at Sams Club and what a hassle it would have been. If you like to lay down and your body sinks just enough to take pressure off your joints this will be the ticket for you!
