Great fit for Sleep Number bed

Love our mattress topper. Not too firm, not too soft. We used it to replace the foam in our Sleep Number bed. It really refreshed the bed and made it feel newer.

Cool sleep

I have had a memory foam mattress for 6 months and sweated every night. I ordered this cool memory foam topper and no more sweating for me at night. This has completely changed my sleep to being wonderful.

Big improvement

I was finding my tempurpedic was way too hard and hot for me and this topper has made it so much more comfortable. Not as cooling as I would like but it really has helped alleviate the discomfort I was waking up with in all my pressure points.

1. quality in wrapping, (they wrapped it in a nice cloth) 2. very supportive and soft I was having shoulder and hip pains, changed to this topper and now I sleep without pain. I have just a smidgen of 1 shoulder letting me know it's still a problem but it is so minor that a little adjustment and no discomfort at all. A 10 year warranty also. Serta is QUALITY all the way on this one!!! odor is quite minor, I may add

Not much cooling effect

I bought this topper hoping it would help me sleep cooler. When paired with Tempurpedic cooling sheets there is a slight cooling effect but after laying in the same spot for more than a minute or 2 I'm back to being hot and have to shift to different spot. When paired with regular Egyptian cotton sheets I honestly don't feel any cooling effect at all. It's very plush if you want to make your bed more soft however I prefer a firmer mattress. At this point the only reason I keep it on my bed is bc I have no where to store it and I don't want to go through the hassle of repackaging and returning.

Sleeping better

I've had this foam topper for several months now. It has been helpful cushioning my day-to-day annoying joint discomfort and helping me fall asleep. The quality seems to be good although I've noticed that it is an inch or 2 short of width on my king size mattress. I'm not sure how if it will help with more acute back and joint pain as you have to lift your body some to turn or move since you sink into the topper.

Serta mattress topper made in USA

Made in USA.. This topper is so comfortable it sleeps great!! We bought the queen size and cut one of the sides off a little to fit in our RV on top of the mattress that is in it. Although our camper is new we wanted it to be as comfortable as being at home and it is with this topper. The foli system is under the mattress so there are no issues with moisture but I dont know if that would've been an issue. We would buy again and we would definitely recommend this topper.

Comfortable, but does not cool.

I bought this to replace a very comfortable mattress topper because it is supposed to provide a cooling sensation. It does not cool at all, but it is a comfortable topper. For comfort, it gets a 5/5, for cooling it gets a 0/5. There is no returning it. Once it comes out of the box it is not going back in. I put the old mattress pad back on my bed and rolled this one up with some bungee cords. It’s taking up a lot of space in a guest room closet until I can figure out what to do with it. I wish I had not bought it.
