  • I loved it, but my partner thought it was too hard or should I say Firm.
Size: King Style: 4" Topper (Bamboo&Copper)
Pain relief is a little overstated as we only slept on it one night. We returned it as it was not compatible to both of us. It was made perfectly. Shipped wonderfully. No problem at all with the quality.

  • Best I have found
Size: King Style: 3" Topper (Bamboo&Copper)
My king mattress is really in need of replacement. But after putting this mattress topper on it, I think I may just get a few more years out of it.

  • This is a firm matress topper, but it works great
Size: Queen Style: 4" Topper (Bamboo&Copper)
I bought this topper to go on top of my medium firm temperpedic which just happened to be way to firm for me to handle. This is a good in between. previous mattress toppers were way to soft, and I would almost be swallowed into them, becuase they wouldnt bounce back fast enough for me to shift around. This one has a nice give, it conforms to the body, but let's you move around without sucking you into the foam. Its definitely not cloud soft, but its comfortable. I have it flipped onto the orange side. The grey side would be way to hard on its own. My hip pain has almost gone away, and it doesn't sleep hot, as far as I can tell. It inflated within an hour, in a relatively cool room. The offgas was strong, and while I waited 8 hours to sleep on it, I had to push it off the bed becuase it did give me some chest and throat pain. After I let it out gas for 24hrs with my air filter on it didn't have a smell. So thats a positive. I'll update my review if it doesn't hold up well over time, otherwise I'm a happy customer. ... show more

  • Great for school mattress
Size: Twin Style: 3" Topper (Bamboo&Copper)
My daughter at first didn't want me to get her a topper. She loved it, and said it made her bed so comfortable. We noticed the charcoal also helped absorb some of the strange smells in her dorm room. Only complaint was her mattress was an xl as most dorm mattresses are and the pad was regular. But she definitely recommended this. ... show more

  • Extremely Comfortable
Size: Twin Style: 3" Topper (Bamboo&Copper)
One side is really nice and firm the other side is a little softer providing the support and comfort I was looking for. Most other ones I’ve tried really don’t provide much support
