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.

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!

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!

Amazing mattress. So comfortable and easy to unwrap from packing. No smell at all. Very durable and support is amazing. Needed a good mattress for backaches. This mattress helps make it easier to sleep now. Love the color.

I purchased two of these total. This is a three part review since I purchased two of these. One is for my little, one is for me, and the last section is experience with unboxing and setting these up. I live with chronic pain, so my experience won't be the same if you don't have chronic pain (lucky you!), so please keep that in mind. The first one was for my little one for the 8" thickness. I specifically looked for proper certifications and fiberglass free memory foam while using naturally fire resistant materials without the additional chemicals. I was hesitant on the cooling gel, but decided for it since they'd need to be kept cool at night. The little says they are warm for a while, but then can feel the cooling gel. They gave it a thumbs up when I asked how they were sleeping on the new mattress. More on this later, since there is a combined section. Trusting my little, I got one for myself too. Being bigger than they are and needing the additional support, I got myself a queen for plenty of space for all of us to cuddle up and watch movies on at a 12" thickness. The jury is still out with me on comfort and sleep quality due to me living with chronic pain and scoliosis. However, considering the old mattress used, I'll give it a bit more time for my body to adjust to it. The bed isn't uncomfortable and the cooling gel works OK for me. I don't feel as warm going to bed and wake up in the morning cooled down. The memory foam does seem so slightly sink your body up to align it better as well, which is most likely the reason I wake up in pain, and why the jury is still out on comfort as my body is still adjusting to the new to it support. It is worth serious consideration if you are looking for a mattress, chronic pain or not. I feel more restful when I wake up in the morning and don't feel as sluggish when I get out of bed. Also, considering that I actually want to go to bed at night is a massive game changer! Now, onto unboxing, setting up, and other parts for the combined section. My thoughts are about the same for either one, which is why it's in one section. Both mattresses came in relative size boxes with minimal extra box material. The twin came in a smaller box because it's a smaller mattress and the queen came in a larger box because it's a bigger mattress. Both of these have different unrolling patterns to set them up before opening the vacuum sealed plastic around them. The twin was just unrolling it, but the roll has the top of the mattress slightly raised up as it was rolled from top into the bottom. The queen had to be unrolled and unfolded to lay it flat, which can be done with one person - but I'd recommend a helper if you have one to make it easier. It states to let it rise for 24 hours, but can speed up the process by walking on it. I let the twin mattress sit, but walked on the queen three times back and forth and was able to sleep on it seemingly fully risen a few hours later. The twin, I had both windows open in the room while it aired out for a few days as recommended per unpacking instructions for the "slight smell". The queen, I had my door open and a fan blowing out (mainly to keep my room cool). Curious as to what this smell was the instructions stated, I smelled the mattress with a deep breath in about 1/8" away from the mattress. Either I have defective smell sensors, or there's a very tiny amount of "new mattress" smell, similar to the new car smell in an actual new car. The very faint odor isn't unpleasant to me and didn't bother me at all. I woildnt recommend doing the same thing if you are sensitive to smells. Both of these are firm and acts like memory foam typically does when you are on it. I measured both mattresses after the 24 hour mark per instructions, and the thickness is 8" and 12" respective to the sizes. I do not remember the cost for each of these specifically, but I also don't skimp out on anything I would do for about 8 hours a day, every day of my life, that can have severe consequences if not at a good quality. I've had pretty bad sleep for more time that I'd like to admit, and finding a good mattress that fits your specific needs beats any price point out there. I'd put a lot more money (thousands) into a bed if that means I get perfect sleep and have a better quality of my waking hours to do all the things I'd want to.

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
