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 am so happy with this Hybrid Mattress! The 12-inch queen size is the perfect balance of comfort and support. The contouring memory foam hugs the body just right, while the innerspring coils add that extra bounce and stability so it never feels too soft or too firm. The cooling top layer has been a game changer, I no longer wake up hot in the middle of the night. The medium-firm feel is spot on for pressure relief, especially for my back and shoulders, and I’ve been sleeping deeper and waking up with less stiffness. It honestly feels like a luxury mattress but at a much better price.

The media could not be loaded. This mattress is extremely comfortable and supportive. It provides a perfect balance between softness and firmness, cradling the body while keeping the spine properly aligned. Pressure points, especially on shoulders and hips, are noticeably reduced.The materials feel durable and high-quality, giving the impression that it will last a long time. Overall, it’s a reliable and comfortable mattress that delivers a restful night’s sleep. Highly recommended.

The packaging was great. Easy to let out of it. Slight smell so it’s good to let it sit for a day or so. Sides are very soft but very comfortable to lay on. I liked it so much I bought another one. Great buy for extra rooms.

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!

Very comfortable and expanded to full size with in a day . It has good lumbar support and holding its firmness . Fabric quality is so good and felt very smooth in texture. For the price paid, it is very worth and considering 12 inch in thickness, will not get a better deal than this.

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.
