Bed is super comfortable. The springs offer full support while the topping is nice and cushy. The medium firmness is perfect. I sleep through the night and don’t wake up with any problems. The bed offers great support for spinal and hip alignment. I’d absolutely buy it again. The smell is gone in about 2ish days. The mattress completely settles and puffs up by the third day. I slept on it before the third day and it was still comfortable. The dimensions line up with what is advertised. Overall, this was a great purchase.

I recently purchased a twin size mattress and it has exceeded my expectations. It’s very comfortable, offering just the right balance of firmness and softness. The quality of the materials feels premium, and it provides excellent support for a good night’s sleep. It arrived well-packaged and expanded quickly without any strong odor. Overall, I’m very happy with this purchase and would definitely recommend it to anyone looking for a comfortable and reliable mattress.

This 10-inch twin hybrid mattress offers a balanced level of comfort and support. The combination of memory foam and individually wrapped pocket coils creates a medium-firm feel that adapts well to the body without feeling too soft. It provides noticeable pressure relief and motion isolation, which is helpful for light sleepers. The mattress arrived without any strong odor and expanded to its full size quickly. I also appreciate that it’s fiberglass-free and CertiPUR-US certified, which gives some extra peace of mind. Suitable for a guest room or daily use.

Just wanted to say how impressed I am with the king hybrid mattress I ordered! It came in a box, which honestly had me a little skeptical at first—but wow, it completely exceeded my expectations. I put it in the guest bedroom, and it feels amazing—super comfortable and supportive. I’m extremely pleased with it. Total win! 👏🛏️✨

The top is super soft but the springs offer support. I threw it on top of her old toddler bed to give it some height and my 9 year old loves it. Unpacking was easy and it inflated to it's normal size very quickly. Will update in 6 months.

First night sleeping on it and it’s a little too firm for me. It does not have much give so I will be purchasing a mattress topper to soften it up a little.

Perfect for kids to sleep. I bought it for my two kids and they are so easy to sweat during sleep. The breathable material of this mattress impressed me a lot. Also, my son loves the firmness. It is firm so I don’t need to worry that kids sink in. I set up the bed without any help as the direction is simple and easy. Highly recommended.

Buyer beware! Do not destroy your box until you’re guaranteed to have had what you ordered! I ordered a 14 inch mattress, paid for a 14 inch mattress! I have given my mattress 3 1/2 days to fully expand and it is still a 12 inch mattress which does not fill the space I was wanting to get to fill.
