Exceptional quality 4” Serta mattress topper! Comes with protective cushiony cover! Zipper glides on throughout the topper very quickly and easily! Had bought a Serta mattress without the topper and this is actually better than the other mattress I bought with a topper! Worth every penny!Thanks again Sams and Serta!

I purchased this King Serra mattress topper over a week ago. After the 1st topper never expanded to form, I returned to Sam’s Club. Thinking I happened to get a faulty product I exchanged for a another and tried again. Same Issue! Second topper never expands. They’re all bad! Don’t waste your time or money

I purchased the queen 4" pillow top and memory foam mattress topper, and it has been sitting out on my balcony for the last 12 hours, because the smell was so horrific i couldn't keep it inside. Thinking it might air out, i just went outside and checked it, and it stinks just as bad as it did. Now, i have to try to figure out how i am going to get this thing back in the box, down 3 flights of stairs, to return it back to the store. What a joke! They better refund my money!

Firstly it arrived in a brown unmarked box -, not a Serta box which surprised me. When I unrolled it there was no sign anywhere of memory gel just fiber. I sat on the topper and it provided no support and literally just disappeared I never actually used it but I cannot see how it is cooling in anyway or that it provides any support / additional comfort to that already provided by the matress I returned it straight away and purchased something else in store

very comfortable

I have now had this mattress topper for 3 or so weeks. It was fairly easy to un-box & set-up. There was NO odd smell or odor. After my first night, I thought it would be perfect, but of course with the test of time - that is not the case. It is comfortable, but it slides, ever so slightly at first and then more each night. In other words, I must removes my sheets every morning and reset the topper back into place and remake the bed. This would not be too bad except that I have a smaller room, so this is quite the chore everyday. Any suggestions on how to avoid the sliding is welcome because that is the only flaw I have experienced. So if you don't mind completely striping & remaking your bed everyday - this is what you want. Again, help or suggestions on the sliding is welcome.

This topper sounded so good and was so bad. It did nothing like it said it would. It was suppose to help with compression points. Not only did it not help but made it worse. It is hot and you can not hardly get in and out of the bed with it. It also hurt my neck. I bought a new pillow thinking that would help but it just made it worse. Plus trying to get it returned as been a nightmare. I am so disappointed in Sam's Customer Care.

For anyone having difficulty with the memory foam not expanding when you take it out of the box, I used a hair dryer on medium heat and just rubbed the memory foam on both sides until it slowly expanded. It took a little while but maybe 30 minutes later it was fully expanded and ready to be put in the cover!

GREAT value

I purchased this for a Christmas gift expecting it to arrive in the Serta box as pictured. Instead, it arrived thrown in a brown cardboard box with nothing anywhere indicating it is a Serta. I am not sure if it is a product someone else returned or if Sam’s Club sent a generic product instead of the name brand
