  • Great Comfort and Solid Support
Size: Queen Style: 10 Inch Pattern Name: Medium
I’ve been sleeping on this Queen Size 10-Inch Gel Memory Foam Mattress for a few weeks now, and I’m genuinely impressed with the quality and comfort for the price. It provides excellent support for my back and hips, and I’ve noticed much less stiffness in the mornings. The gel memory foam really works. This mattress stays noticeably cooler throughout the night. It gives peace of mind knowing the foam is made in the USA and doesn’t have harsh chemicals or odors. There was only a very slight smell when first unboxed, and it disappeared within a day. It arrived well-packaged, expanded quickly, and was ready to sleep on within 24 hours. For anyone looking for a comfortable, cooling memory foam mattress with good back support and safe materials, this is a fantastic choice. Great value and quality, I would definitely recommend it. ... show more

  • The medium firmness of this mattress is great
Size: Queen Style: 10 Inch Pattern Name: Medium
I highly recommend this mattress. The fabric feels very soft and comfortable to the touch. What I like most is its medium firmness—it’s neither too hard nor too soft, and it feels extremely comfortable to lie on. This feature really stands out to me and makes the mattress feel like an excellent value for the price. When it arrived, the mattress was folded and packed in a box. After unfolding it and letting it sit flat for about a day, it fully expanded to its original shape. It became very smooth and even, with no unpleasant odor at all. Overall, this is one of the best value-for-money purchases I’ve made. I’m very happy with my decision to buy this mattress! ... show more

  • Get it!
Size: King Style: 12 Inch Pattern Name: Medium
LOVE IT!! Very comfortable only on my first night sleeping on it but so far it’s great I got the medium firm BUT ITS VERY VERY FIRM if you have a partner like I do I didn’t feel the movement from him and very very soft!! I do wish it wasn’t as firm and had a bit of bounce to it but that probably because I’m not use to this kind of mattress no noise when moving very very heavy easy to put together great great quality mattress not sinking very very thick I WOULD DEFINITELY RECOMMEND THIS MATTRESS! ... show more

  • Love this mattress.
Size: California King Style: 14 Inch Pattern Name: Medium
It's been 2 weeks now and I absolutely love my mattress. No more hip pain and the mattress is so soft and comfy. After reading prior reviews, I was worried it would be hard, but it was not! Hubby seems to like it is well. He is a big man, 6'3" and a bit over 200lbs and at some point I'm sure there will be a sink hole, but I'm hoping it will be a while down the road. It inflated quickly and we did walk on it a bit as one corner was being stubborn. We left it in the box for a couple weeks waiting on the platform I ordered separately. Came out fine ... show more

  • Great value, squishy yet supportive.
Size: Queen Style: 12 Inch Pattern Name: Medium
I originally ordered a Zinus mattress on sale from prime day, but after it was shipped they refunded the order. So I shopped around again and found this mattress that was still within my price range. They also claim to be an American company which is preferred. The order came in within 3 days, being shipped out of Texas. My first impression when the box arrived was impressed, its smaller and not as heavy as expected. I’m 5foot lady and was able to wrangle it into the back of my car(it was sent to my work) and able to roll/lift it into my apartment. After setting up the frame I unboxed the mattress and figured out its folded in half! I unfolded and put it in place on the frame and started to rip the bag open and it started inflating immediately. There was no strong off putting smell, and the plastic was perforated in a way that made it really easy to get out from under it. The mattress looks great, the quality seems really nice and the cover fabric is luxurious to the touch. So the website says it’s “ready” in two hours but the mattress itself comes with a paper suggesting 24 hours. After about 3 hours of opening the bed I took a tape measure and almost all sides were within a quarter inch of the full 12 inches. So I put a mattress protector & sheets on and spent my first night on it. At first when the mattress was inflating it was very soft and squishy, but as it inflated it became more supportive. I am a stomach sleeper with a larger chest and this mattress is the perfect amount of give for pressure points while still being overall very supportive. I wasn’t hot at all and am very happy I made this choice! ... show more
