ThermaGel Memory Foam Mattress Topper, King, Blue | 3 inch king gel memory foam mattress topper, ThermaGel cooling, deep pressure relief, CertiPUR-US certified

Ordered a mattress in a box and found it had good support, but FAR too firm so we ordered this topper. In so glad we did! It's like sleeping on a cloud! The best sleep I've had in a close to a decade!

Package arrived on time and was well packed. We removed it from paking and removed shipping plastic, then allowed it expand per the instructions. It had no offensive odor at all; in fact it was a pleasant smell if anything. The next day we placed it onto our mattress (it was easy to placeand it stays in place well), put the sheets on, and at bedtime we climbed in. The topper provided an excellent mixture of softness and support. It has not run hot at night and is very pleasant to sleep upon. It appears to be a very durable topper.

EXACTLY what i wanted. My family bought me a similar Serta topper 5 yrs ago after a major surgery. My matress has seen better days. The first one was very comfortable and I was still using it but my large dog digs at the bed before laying down and did rip it. Honestly, the first one was a little too soft. I had a full open abdominal so those muscles were cut and I have bad joints , so sitting up can be tricky. I found you sink in and had to actually roll to get up. This Serta topper is much more comfortable & much easier to get up from because all though soft, it is firmer. It bounces right back after you get up. . It gives but doesn't make you sink. This helps sleeping when you have joint pain. I didnt feel as hot with it as much as the first either but could just be me. It came in a solid box ,( grandkids LOVE the box with the sheep and large flaps lol) compressed, well wrapped and in a duffle bag. It was fully expanded as soon as I opened it. I didnt notice any smells. This was the best sleep I've had in a long time and at this price I've considered buying an extra when it inevitably rips and wears down but I've read some reviews online that toppers didn't fully expanded after stored a long time. Ill just enjoy this till it dies and replace it then. It was very fast shipping also. I HIGHLY RECOMMEND THIS & WILL buy again!

Very satisfied with the topper. Only complaint that I would have is that it could be a little bit firmer. It did make my bed feel way more softer, which is a good thing but a little more Posturepedic Support would be better.

Purchased for my 5th wheel RV mattress(king), which wasn't very comfortable. After opening it up and spreading it out my first thought was, this isn't going to spread out enough to cover the mattress. There was no odor what so ever. I did what the directions explained, which was wait. I think I went out there after 3 to 4 days and it looked great(A little surprised). I waited a couple more days, trimmed off the two bottom corners and put on the sheets. Camped several weeks and it was very comfortable. Make sure and wait, don't rush to sleep on it. A couple days ago I decided to order one for my Cal King mattress in the house. For this size there's about a $106.00 delivery charge so, went with another brand. Wish I could have went with another one of these but not gonna pay that for delivery. I have no idea why I didn't take a picture after it was aired out and completed but believe me, it was perfect.
