This is a great mattress at a great price. Very comfortable and supportive while also having that soft upper layer comfort. I have had this for a few weeks and find it to be well made. I was surprised how heavy it was when delivered. I’d recommend the 12 inch thickness as it offers great support while being manageable for bedding sheets. I slept on it one night and I am 240 lbs with lower back issues from two spinal fusions and I had a great nights sleep, feeling good in the morning. I just had two family members in from Houston who slept on it two nights as well. It’s in the guest room and they loved it too. The woman is 140 lbs and the husband around 300 lbs. Both commented how great they slept and they are now buying the same mattress for their home. I don’t agree with a few comments about edge support being poor. The edge support is as good or better than mattresses I have used from top manufacturers at 3 times the cost. The issue from these customers may be that they either received their mattress beyond the 3 month manufacturing date or they let it sit a while before opening. Make sure the created on date or manufacturing date label on the outside of the box is less than 3 months from when you receive it. If not, return it before opening. If it was manufactured less than 3 months from receiving it make sure you open it within two days and then allow it to sit and expand over a full 3 days (72 hours) before using it. A vacuumed packed hybrid mattress (memory foam and independent coils) can suffer from permanent deformations in the foam and coils if not opened within that 3 month period from manufacturing. All I can say is this is a great mattress for a great price. I seriously doubt you can find anything better at a price point of around $200 for a 12-inch thick queen mattress. Firm yet soft at the same time. Sweet dreams!.

I bought this Queen size hybrid mattress a few weeks ago and it has been one of the best decisions. The combination of memory foam with interior springs is perfect: it provides the ideal support while still feeling soft and comfortable. The cooling top layer really works, I no longer wake up sweating at night like before. In addition, I have noticed great relief in the pressure of the back and hips. I wake up much more rested and without pain. Another plus point is the 365-night trial. It gave me a lot of confidence to know that I could try it calmly. But honestly, from the first night I knew I wouldn't return it. I totally recommend it if you are looking for quality, freshness and comfort in a single mattress!

I bought this 12-inch Queen hybrid mattress just three days ago and I can already say that it was an excellent choice. The combination of memory foam and interior springs offers a perfect balance between softness and support. The cooling layer is a wonder, as it keeps the temperature cool all night. From the first night I felt a deep and comfortable rest. I wake up without the tension in my back that I used to have, and it's only been a few days. The edge has good support, so it feels firm even when sitting. It arrived well protected, it was easy to open and expanded quickly.

The media could not be loaded. I got this mattress and by far it’s been great! I been having a great sleep, very comfortable and the firm is good on the back. The set up is easy, just take it out of the bag and let it sit for a day to fully rise. The price is great and it gets delivered to front door which in my opinion I love! I recommend this mattress if your looking for one.

This mattress is everything I was hoping for and more. The medium firmness is perfect — supportive yet comfortable. I’ve been sleeping on it for a few nights now and I already notice a big improvement in my back. The top layer feels soft and breathable, and the cooling effect really makes a difference during warm nights. It expanded fully within a few hours and had no unpleasant smell. Great quality for the price — highly recommend!

After weeks of research, I decided to try this hybrid mattress — and I have no regrets! It has the perfect balance between firmness and softness. The foam adapts to your body without sinking too much, and the inner springs provide excellent support, especially for the back. Since I started using it, I wake up without pain and feeling much more rested. Also, you don’t feel your partner’s movements during the night. I highly recommend it.

I bought this 12" mattress without knowing its quality and I can tell you that it is super comfortable, I really like its comfort. The memory foam is the perfect firmness, neither too soft nor too hard and immediately resumes its shape after moving or getting up. It is incredible, firm and comfortable which makes it perfect for the body.
