Feels Like Sleeping on a Cloud
Color: White, Size: Twin, Color: White, Size: Twin
The quality is excellent, it stays in place well, and it adds the perfect amount of cushion without feeling too heavy. I wake up feeling more rested and without body soreness. Definitely one of the best purchases I’ve made for better sleep.

Very soft for the thinness. Would buy again if needed
Color: White, Size: Full, Color: White, Size: Full
I bought this four days ago and so far so good. I threw it in the dryer for 40 minutes and it fluffed up very well. I, unfortunately, bought my new full mattress too firm and needed more support. This topper came to be the most affordable option for me and as of now, my partner and I love it so much. It hugs us very well for the padding to be fairly thin. Wish it could be a tad bit thicker but it’s very soft and I can’t wait to lay down after work!

Comfy
Color: Grey, Size: King
It's comfy not as thick as the picture makes it look but definitely improved our sleep after being on a rock hard mattress for so long. It smelt a little funny when first opened it but went away with fluffing it. Fits our king sized mattress perfectly. It's kind of like sleeping on a fluffy comforter.

Wonderful, great finitions
Color: White, Size: Queen, Color: White, Size: Queen
I thought of a size "full" when I ordered a queen size for my French 140cm x 200cm guest bed. When I received the package and realized I had made a mistake, I was despaired because I had no time to change it so I went to look for bed size equivalences between France and USA. At the end, I thought I could give it a try so I did, and I am so happy I did because it perfectly works! I am so relieved. The top mattress is padded, even just coming out of the package. I am still going to let it take its fluffyness for a few hours! 3asy to unpack, to install, to use!!! Easy to wash, easy to dry! I usually wash PADDED top mattresses with a cup of vinegar to sanitize and I always add the necessary amount of laudry powder only on a semi warm cycle. I let the top mattresses dry in the dryer with new zealand woolen balls to increase the fluffy aspect, but always on a soft cycle or with cold air. It takes a bit of time, but it is gentle on the microfiber fabric!
This queen top mattress is very comfy and it should please my guess! FYI, if you like to sleep on a hard or firm mattress forget this one, it is very soft!!! It might not be for your back depending on what you suffer from, but suffering from lombalgia, it relieved my pain when I slept on mine, though. Remember just that sleeping well is, among other things, a question of possitions...like on your left side to help your stomack, or on your back. I do not know it it helps to cool down, especially because it Texas at night it is warmmmm! All in all this white padded top mattress seems to be a good quality product. It was a steal being for sale at half price! It fits perfectly thick mattresses too and the elastics are solid. My guests will sleep like angels👍

It’s ok
Color: Black, Size: Queen
It’s a very nice mattress topper. Is comfy, but it’s not as fluffy as advertised. And it is not cooling.
