I received this mattress about a week ago and have been using it so far. The mattress is not that heavy that I can unpack it by myself. There were no smells when I first opened the package, which I think is because of the charcoal support layer. The material is soft and breathable. It is softer than my old mattress but does offer a great balanced support for different sleeping positions. I like the grey and white combination that looks very neat. The high density foam layers do help some to absorb movement for a light sleeper compared with my old mattress. I would say the over quality is great, the only thing is as seen in the picture, the bottom left corner of the mattress did not fully expand after unpacking. Other than that, the mattress has great overall resilience. Price is great for a queen size mattress over the market.

I got a twin size, it fit perfectly in the bed frame that I own, not too big not too small. The weight of this bed is pretty light which is great for changing bedsheets. I’ve been sleeping pretty well on this mattress surprisingly, it very soft and I usually wouldn’t go for soft mattresses. It’s great!!

I’ve been looking for a mattress that offers true firm support, and this one exceeded my expectations. It’s not too hard, but just the right amount of firmness to support my back and keep my spine aligned. After sleeping on it for a few nights, I noticed my lower back pain has significantly improved. The materials feel high-quality, and there’s no chemical smell upon opening. Highly recommend for anyone who prefers a firmer sleeping surface!

This mattress exceeded all my expectations! The packaging was secure, and the included instructions were crystal clear, making setup a breeze. It expanded quickly and had no strong odors. The firmness is just right—supportive yet comfortable—and I fell asleep almost instantly. Waking up feeling refreshed and well-rested has been a game-changer. Highly recommend this to anyone looking for a high-quality mattress at a great price!

I am very happy to have bought such a comfortable mattress. The price is very moderate, very comfortable, no odor. I bought a 12-inch one and laid it directly on the floor. The height is just right. Worth recommending

This is a nice comfortable king mattress, great value for the price! The top is soft and feels like memory foam, but the mattress itself is reasonably firm and doesn’t deform. I usually put a memory foam top of my mattresses, but this one doesn’t need one.

The package was very small. I was surprised that how big it can expand. It is very thick, and its texture feels so comfortable. I like this type of memory foam. It's great for my lower back.

This mattress is just right — supportive but still soft. It’s breathable, so I don’t overheat at night. For the price, the quality is excellent. A great buy if you want comfort and cleanliness without spending too much.
