Great topper

Hubby and I have a split king adjustable bed with latex foam mattresses. The mattresses are too firm so we purchased two Twin XL toppers. Opened up them up, put them in the pillow top cover and they molded to the beds right away. Oh my, they are so comfortable! They made our mattresses feel wonderful. However, after a couple nights of sleep the pads start shifting in the pillow top covers and off the mattress. The separation of two Twin XL mattresses now feels like a 6" valley in the middle as the pads both shift outward. We wanted to keep the individuality of the adjustable beds, but maybe we should have purchased a king sized topper. We've tried everything we can think of to keep the toppers in place; nothing is working. So if you have a split king like we do, I wouldn't recommend them for this type of bed.

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

Very Nice

Paid $149 at Sam's Club. I bought this a couple of months ago and it is extremely uncomfortable and it constantly slides off our bed no matter what we do. We end up having to pull it back onto bed few times a night. I have not slept well since I put it on our bed. We gave it time thinking it would relax or something but is worse over time not better. I don't know if Sam's club will allow me to return it, if not it will unfortunately be landfill!

No more tossing and turning from hip pain. It's also very comfortable! The mattress topper is very cheaply made! But the memory foam topper is.so so comfortable! It has made my bed feel like a new one, without buying a new one! I definitely recommend it! It does sink in, but it doesn't slide off my mattress like others have said. I do have a fitted sheet over it, to keep everything in place. I am a side sleeper.

Very comfortable

Made my hard bed comfy.

This item was a major disappointment for me. While advertised as having a medium firmness, it was actually far beyond soft. So soft that that it began to cause joint pains in my knees and shoulders from sleeping in a curved (downward) position. That's how much give this has. Furthermore, nothing on earth could keep this thing from constantly sliding around on top of the underlying mattress. Every morning, it would be hanging of the bed by about a foot, and every morning I would have to correct it and re-do the fitted sheets. Overall, there is nothing positive I could say about this item.
