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.

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!

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.

The media could not be loaded. Only been sleeping on this for a few nights but I can already tell it was a good buy. It has a comfortable medium-firm feel that gives you support without feeling too hard. The top layer has a nice cushion to it, and I’ve actually been sleeping through the night without tossing around as much. Setup was quick and easy. Once it was fully expanded, it looked and felt like a premium mattress. The edges are also sturdier than I expected, which is great when sitting on the side. Overall, definitely happy with it so far.

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. This queen mattress is incredibly comfortable — not too soft, not too firm, just the perfect balance. I’ve been waking up without back pain, and my sleep feels so much deeper and more restful. It expanded quickly after opening, with no strong odor, and fits perfectly on my bed frame. Excellent quality for the price, and I couldn’t be happier with my purchase!

Absolutely terrible. I may be a month or two in and I’m already feeling springs. The pictures completely are totally disingenuous. It’s maybe an inch and a half of foam and then springs. I’m extraordinarily disappointed. Do not buy this mattress.
