Size: King (U.S. Standard)
Style: 12inch
I used to have trouble sleeping and sore back, but since switching to this mattress, I feel completely different! Lying down, one is instantly enveloped by a gentle sense of support, with a moderate softness and hardness that perfectly fits the curves of the body, as comfortable as sleeping in clouds. Whether sleeping on the back or side, the waist and shoulders can receive good support, and the noise reduction effect is also very good when turning over, without affecting the partner at all. The material is finely crafted and has good breathability. After waking up, I feel refreshed and my back and waist pain are significantly relieved. The logistics are super fast, and the customer service is also very patient in answering questions. I truly feel that buying such a high-quality mattress at this price point is a great value! Highly recommended for friends who value sleep quality!

I’ve been sleeping on this mattress for a few days now, and I love it! It came well-packed, expanded quickly, and had no weird smell. The support is great—firm enough for my back, but still super comfy. I used to wake up with back pain, but not anymore. Now I sleep through the night and wake up feeling rested. It’s not too soft or too hard—just the right balance. Whether I sleep on my side or back, it feels comfortable. Plus, when my partner moves, I don’t feel a thing. Great motion isolation! Overall, this mattress is a great value. I’m really happy with the quality and would definitely recommend it to friends and family.

I always woke up with back pain from sleeping on my previous mattress, but this mattress has good support. I feel my waist is supported when I lie on it, and I don’t feel back pain after sleeping for a few days. The fit of the waist is very good, and there is no sense of suspension. The mattress is big enough, and rolling around is no problem. It is more comfortable than expected.
