Checks all my boxes!
Color: Blue(waterproof) Size: Queen
I don't often write reviews, but I couldn't pass this one up. This cooling mattress topper checks all the boxes for me! After just one night, I woke up feeling rested and without that sweaty, moist over-heated feeling all over my body. I felt like I had slept on a cloud with this topper's cushy/plush top, with the feel of a cool pillow. It fit our Queen size bed perfectly, even over our 3" memory foam mattress topper. The wonderful deep pockets were able to reach completely over and under the mattress edge. Please note, I haven't washed it yet, and even though it states to wipe surface, I believe it could be cleaned in a front loader washing machine. Very satisfied with this purchase!! ... show more

Works for us
Color: White Size: Queen
Nice replacement for the previous mattress topper we had. It covers the complete mattress and love the deeper sides. I did not notice any odor and my husband hasn’t complained about getting too warm.

a bit misleading and not a thick mattress topper
Color: Blue(waterproof) Size: Queen
bought this thinking it would be a solid memory foam mattress topper. after unpacking it and letting it expand, it really doesnt expand much more from unpacking it. its a small amount of shredded memory foam with a very thin layer of memory foam on top. its decently soft and is surprisingly cool to sleep on but i wouldnt buy this if it wasnt on sale. its not bad but wish i just picked one up in store. ... show more

Comfortable
Color: White Size: Queen
The DOWNCOOL Queen Mattress Topper delivers an impressive balance of cloud-like comfort and ergonomic support. Featuring high-density memory foam, it contours around your body to relieve pressure points, making it a great solution for reducing lower back and hip pain. What sets this topper apart is its temperature regulation. The viscose cover—derived from bamboo—is exceptionally breathable, soft to the touch, and actively prevents overheating throughout the night. Furthermore, the deep pocket skirt securely grips mattresses ranging from 8 to 21 inches, keeping the pad firmly in place without shifting during sleep. For anyone looking to revive a firm bed or add plush relief, it is a high-value upgrade for a cooler, pain-free night's sleep. ... show more

Great mattress topper
Color: White Size: Queen
This is a well made mattress topper. No strong chemical smell and also washed nicely though took a while to dry because it's so plush. Great price too.

Great Value
Color: Blue(waterproof) Size: Queen
After looking at more expensive mattress toppers with mixed reviews., I saw this topper on sale at a great price. This mattress topper is very comfortable and well built. Also, the material quality is excellent. Unlike other toppers with straps or shallow corner pockets, , this topper has deep corner pockets that are snug and tight. My Tempurpedic mattress is about 5” thick and the topper corner pockets easily fits the mattress. It may take a while to work the corners into the mattress but it’s worth the effort. Once installed, it covers the mattress perfectly, stays in place and does not shift. The topper thickness is ideal and it feel slightly cooler. Overall, this topper is a great value for the cost. ... show more
