This mattress has the perfect balance of plush comfort and firm support. Whether you sleep on your back, side, or stomach, it adapts beautifully to your body. I used to wake up with lower back pain, but since switching to this mattress, I feel rested and pain-free every morning. If you’re on the fence, don’t hesitate. this is high-quality memory foam at a great price. Highly recommend for anyone looking to upgrade their sleep without breaking the bank! Unboxing was super easy, it expanded quickly and didn’t have that strong chemical smell you usually get with foam mattresses. I let it sit for 24 hours just to be safe, and by the next day, it was fully fluffed and ready to go.

This Mattress is better than the “novaform” from Costco. Its medium firmness is spot on. It didn’t take forever to inflate. I got no smell upon first opening it. There’s no sagging in the corners. I was laying comfortably on it within 2 hours. Now for the wear & cooling sleep test. I’ll be back in 6 months with an update.

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!

I needed a good mattress that is supportive yet soft enough to not cause pain in my aging hips. I am absolutely mystified at how nice this mattress is for the price. It "fluffed" up rather quickly, which was surprising. It is very comfortable, and truly a medium firmness as described. There is no motion transfer from my husband moving around. It was delivered on time. I highly recommend this mattress! I went with a 10" mattress because it is not as heavy, making it much easier to change the sheets.

Amazing mattress! Highly recommend to anyone who is skeptical buying a mattress online. Mine arrived a day early and inflated full size within a few hours. It is a perfect medium firmness and you sleep like a baby. I didn’t notice any smell when unwrapping, and it is very easy to set up.

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.
