I am absolutely delighted with this 14-inch hybrid mattress. The combination of gel memory foam and individually wrapped innersprings provides incredible pressure relief and perfect support for my body. The medium firmness is just what I needed to stop experiencing back and neck pain. I love that it comes in a box and is easy to set up. The quality of the material is excellent, and the design is very innovative. After just a few nights of use, I can say that I have significantly improved the quality of my sleep.

The media could not be loaded. I'm really pleased with the comfort and quality of the 12-inch queen size hybrid mattress that I recently bought. The ideal ratio of softness and support is provided by the individually wrapped pocket coils and gel memory foam. The mattress has greatly enhanced the quality of my sleep by offering great pressure reduction, particularly for my hips and back. The medium-firm option, which I chose, is the ideal amount of firmness—not too hard, but still encouraging. It was simple to set up because the mattress arrived in a box neatly coiled up. When unpacked, it expanded rapidly and smelled fine. I saw a significant improvement in my sleep quality after a few nights, with less tossing and turning.

Pretty decent for a box mattress, it's my first one. I have slept on it for a month or so. It feels firm, but not too firm. We'll have to see how long it lasts.

Say hello to my new sleep throne — a 14-inch queen mattress that’s firm, supportive, and absolutely in charge. No sinking, no sagging, just solid comfort with the perfect amount of plush on top. Whether you’re a side sleeper, sprawler, or pillow-hugging starfish, this mattress holds its own and keeps you aligned all night. I woke up feeling like I just got upgraded to first class — at home. Big, bold, and boujee in the best way. Sleep goals: achieved. 😴✨

This is the best mattress I have ever purchased. And I will definitely be buying again for my children’s room and any guest rooms. The way the mattress is set up, I don’t get any pressure point sores, absolutely no back pain, and I sleep amazingly. I would not hype this mattress up if it truly didn’t deserve it. It fits perfectly to my needs and looks expensive. I have yet to have any issues. I truly do not want to go on vacations or start the night anywhere other than my bed lol. 10/10 recommend to anyone!

Very comfortable bed, inflated very quickly. Was super scared of ordering a bed in a box but I’m impressed with the quality of sleep I’ve gotten. Soft to the touch. Would recommend

This mattress is an incredible bargain, I bought a Casper Hybrid about 3 years ago and it quickly started to breakdown and sag in the middle. I was having all kinds of back pain. I ordered this mattress for my guest room and found myself going and using this bed instead of my Casper. I would wake up with no back pain and have a very restful sleep. So I decided to replace my Casper with the same mattress, and I couldn't be happier. I am a side sleeper and I had the most restful nights sleep and woke up zero back pain. I did buy a bamboo topper for my mattress to make it a little more soft on the top but overall I am very happy.
