  • Comfort and support in one
The media could not be loaded. I'm really impressed with this new mattress. As someone who's suffered from back pain, this mattress has been a game-changer for me. I've only had it for a week, and I can already feel the difference. The pain I used to wake up with is significantly reduced. The unboxing was easy, and it expanded to full size within an hour. The quality is great, and the comfort level is just right. I love the medium firmness, it provides a good balance of support and pressure relief. The zoned back support is a great feature, and I can feel the difference in my spine's alignment. The motion isolation and edge support are also nice touches. I've been sleeping better, and I wake up feeling refreshed. The 365-night home trial is a nice peace of mind. Overall, I'm really happy with this mattress and would definitely recommend it. ... show more

Wow! I was not expecting such a nice structured mattress at this price point. My guests say it's very comfortable.

  • Fresh mattress for a new house
We recently moved into a new house, and I wanted all our mattresses to be brand new to avoid any bed bugs or anything unwanted. This mattress has a nice weight to it and feels wellmade, with premium materials. I love the firmness it’s great for my back. The overall appearance looks clean and structured, and the shape is perfect for my taste. The size measurements are exact, and the price is much more affordable compared to other brands. Most importantly, it gives me a good night’s sleep. ... show more

  • Very good and comfortable material
This Queen Hybrid Mattress is a game-changer for sleep! The medium-firm feel provides perfect pressure relief and back support, exactly as advertised. I love the motion isolation—I barely notice when my partner moves. The edge support is fantastic, and the 14-inch height feels luxurious. Highly recommend for a truly restful night! ... show more

  • Totally Worth It!
We let the mattress fully expand for 72 hours just like the instructions recommended, and the result has been amazing. From the very first night, it felt incredibly comfortable—soft enough to relax into but supportive enough to keep your back aligned. I wake up without any back pain, and the overall sleep quality has improved so much. It really feels like sinking into a cloud. Highly recommended for anyone looking for comfort and support in one! ... show more

  • Terrible quality
Size: Queen Style: 12 Inch
This topper is full of springs. Very uncomfortable. Not enough covering. I have to purchase a mattress topper for comfortably. I can not return because it’s already open
