I had the luxury of sleeping on this before buying in a friends guest room. This has the perfect amout of give where needed. This will definitely extend the life of my current mattress. However, you will need deep pocket sheets to accommodate the added 4".

I bought one of these a few months ago and wow was it sooo comfy like sleeping on a cloud. So I bought one for my son who has damaged nerves in his legs and wakes up constantly from the pain, he has been sleeping soundly through the whole night since he got it. Then I bought one for my mother-in-law who has arthritis and suffered from restless nights, she too is now sleeping comfortably all night long. Both say they are also sleeping on their backs instead of their sides now too. I suggest opening it on your bed, there is absolutely no smell and you can sleep on it within an hour or two.

This memory foam topper is comfortable and I slept like a baby on a mattress that was less than desirable to sleep on prior to using it. Let me warn you that it it seemed like I was wrestling an alligator trying to put the cover on the foam. But once I did it was my own little piece of heaven. It did not slip or slide from the mattress as other reviews had stated. I was using it in the summer in Arizona and never got hot. It was for a twin size mattress. Best investment made in a long time.

This mattress topper provides the perfect balance between snuggly comfort and support. I have used it for a week and have been sleeping better and more soundly during that time. My mattress without the topper was fine but it did not have a pillow top. The addition of the topper has added the cocooning effect of a pillow top but with the added support and benefits of memory foam. I highly recommend the product.

I bought a new mattress from Sams about 3-4 years ago. It was comfortable but too firm my 5'1 (250lb) body. I currently have lower back problems due to excessive lifting that has caused my back to contour and me losing countless hours of sleep. After buying this i am able to get my restful nights back and wake up feeling refreshed.

I bought two of these a couple weeks ago for my children. My son had stopped sleeping in his bed and started sleeping in mine because he said his bed wasn't comfortable after i got these toppers my only problem is i cant get them out of there beds in the mornings because there so comfortable.

This is the second mattress topper by Serta I've owned and I'm pleased that the only change seems to be in the cover for the pad which is not a bad thing. The topper is on my Serta mattress so what more can I ask for. The topper isn't used to rehab the mattress; I just like the "extra" it gives. Price is great for replacement every couple of years. I would definitely recommend this topper to anyone who just wants that little extra comfort.

Nice replacement for a 3" memory foam mattress topper that had run its course. I would have given 5 stars but after two weeks of nightly use it still has not "stretched" out to cover the length of the King size mattress. The owner's manual states that the topper may appear smaller than the mattress and that is normal. It advises to sleep on it and it will stretch out. If it ends up doing so I will update the rating.

the mattress topper pad slids off the bed. Every morning have to remake bed to get pad back where it belongs. It bunches up and you are continully trying to get comfortable thru the night. you cannot just roll over you have to lift yourself up or it moves with you. My lab even quit sleeping in the bed since putting on this pad and he has slept in our bed for 5 years.Would not recommend this product and going to return on next trip to Sams Club

We purchased a king and full size topper just like this one in the past and loved them. However, this full topper we bought for our guest room has a strong, very bad chemical smell. We aired it out for days before putting sheets on the bed. But then we had guests and had to use the bed so I ran a fan and used febreeze to mask the smell a little. Took the sheets off after they left, washed everything because it smelled like the memory foam funk, aired it out for days and thought it was better. I laid on the bed yesterday and smelled it again! Very frustrating!
