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.

COOL, COMFORTABLE & CUSHIONY
Color: White, Size: King
I Love, Love, Love this Mattress Protecter, Cover, Topper, it is "thick, cool, beautiful and just the right size for my bed, I purchased it "King Size" because I like it to go all around my mattress so it covers and protects "all of my mattress". It is Fluffy, just enough Padding to Support your body's weight. I had one previous to this one, it was the same brand, the same comfort and I've had it for Years, it is very Durable and Stain /Resistant. I have no complaints. I am going to try to upload a short clip, please bear with me, it's my first time posting a video and I am an amateur...I hope you love it as much as I do because you will have years of use with this "Mattress Topper".

Would recommend!
Color: White, Size: Queen
I bought this mattress topper for my teenage daughter for her bed. It was on sale when I purchased it and when it arrived I loved the quality and softness of the topper. Great buy for the price! It stays in place and fits as sized. I have yet to launder it, but I would assume it will wash up just fine. My daughter loves it and makes her bed dreamy.

Saved me so much money
Im loving this mattress topper. It has added a noticeable layer of comfort to my firm mattress without making it feel too soft. The cushion is plush yet supportive and has made sleeping more comfortable overall.
The bamboo feels soft and breathable. It fits on the mattress with the deep pockets and stays in place alk night. Setup was easy and it fluffed up after unpacking.
If you have a firm mattress and want extra comfort without replacing it, this topper is a great option. Highly recommend

Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.
This 3-inch mattress topper instantly upgraded my bed with a softer, cooler, and more supportive feel. The bamboo-viscose fabric is noticeably breathable, helping regulate heat throughout the night—great for hot sleepers. The 1200GSM down-alternative fill adds plush, cloud-like cushioning while still offering balanced support for the back and shoulders. It fits securely with the deep pockets and stays in place even when turning. After allowing it to fully expand, the topper fluffs up beautifully. Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.
