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

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!

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.

Very comfortable. Used on RV mattress.

So comfy and more cost effective than buying a new mattress!

Very comfortable and love the zippered mattress cover.

Too soft. More like a soft piece of foam on the bed.

Comfy and stays in place on top of my other mattress.

This topper was extremely HOT n not comfortable at all. I returned it.

I have back problems and the memory foam topper 4" has helped me sleep more comfortablu
