Pattern Name: Medium Plush
If you’re a hot sleeper who struggles with back pain, this mattress is an absolute dream. I was a bit skeptical about a "mattress in a box," but it arrived in a really manageable package and was incredibly easy to set up. Once it fully expanded, the first thing I noticed was the cloud-like comfort. The memory foam layers do a fantastic job of cradling your body, which has been a lifesaver for my pressure points. It has that perfect medium-plush feel—soft enough to feel luxurious but supportive enough that I don't feel like I'm sinking into a hole. One of my favorite features is the cooling gel and green tea infusion. I usually wake up sweating, but the airflow design really does help move heat away from your body. I’ve stayed much cooler throughout the night since switching. It’s also a total win for couples; the motion isolation is top-notch. My partner moves around a lot in their sleep, and I honestly don't feel a thing on my side of the bed anymore. Finally, it’s a huge relief to know this is a fiberglass-free and certified safe product. You can tell the materials are high-quality, and there was no harsh chemical smell when I first opened it. It fits perfectly on my queen frame and has turned my bedroom into a little sanctuary. If you want a premium sleep experience without the massive price tag of a traditional furniture store, I can’t recommend this enough!

This 10" queen mattress is great if you require medium plush support, a cooling design and motion isolation for undisturbed sleep. The top layer contours and cradles your body. The supportive base provides pressure point relief and proper spinal alignment whether you sleep on your side or your back. I'm not sure of the efficacy of the green tea extract infusion, but the cooling gel beads and egg crate airflow layer keep me from getting overheated at night. This is especially helpful for my hot flashes and hot summer nights when I like to sleep with the window open. The motion isolation helps a lot too. I am a very light sleeper, and the slightest movement causes me to wake easily. On this mattress I am no longer awoken by my husband getting out of bed at night, or the dogs jumping on and off. This mattress is CERTI-PUR U.S. certified. This means the mattress is free of harmful chemicals and fiberglass. I will not buy a mattress that does not have this certification. This mattress also comes with a removable cover, which is amazing. I can wash this every few months and not have to worry about dust mites. So far, it's been a very restful, relaxing, comfortable mattress.

We are very pleased with this mattress. It comes rolled and vacuum packed in thick plastic. It does take almost 24 hours for full expansion of all the foam to take place, which is expected. And I would reconsider the quality and density if it didn't. The mattress cover looks and feels quality. I made sure I already had a good cover of hand before even beginning to unbox this mattress. We really feel that they improve the overall life of a mattress. This mattress is quite comfortable for us. My husband has some increasing back problems and our mattress was getting older and not giving the support he needed at night. This offers much better overall support and sleeps well. Coupled with our cooling mattress pad we find that this mattress sleeps cool. We have slept on memory foam mattresses in our house for more than 12 years now, and this one holds its own with the expensive name branded one we purchased as our initial memory foam investment. We did not find any noxious odors associated with this mattress at all. This mattress is OEKO-TEX and CertiPur-US certified, and has a 10 year warranty. All of these qualities and it doesn't break the bank. This mattress is a great value. Recommended!

We bought this mattress for my daughter as she moved into a twin bed and it has worked well so far. I was a little unsure about the thickness at first since we chose the 10 inch option but it fits the bed nicely and feels substantial enough for daily use. We went with the medium plush feel but to me it leans more toward medium firm. It is not as soft as I expected yet it still feels comfortable and supportive. That firmness actually seems to work well for her and she has been sleeping through the night without any complaints. One thing I really appreciate is the removable cover. Being able to take it off and wash it feels essential for a kids bed. The cover itself has a nice texture and adds some softness when you lie down. It makes the surface feel more inviting. The cooling aspect has been good so far. My daughter tends to sleep warm and she has not mentioned feeling overheated. Another pleasant surprise was the lack of smell. Most memory foam mattresses come with a strong scent at first but this one did not have that issue at all even right out of the packaging. It did take a bit of time for the corners to fully expand. After a few days everything evened out and the shape settled properly. Overall it looks great on her bed and has been a comfortable and practical choice for her transition to a bigger bed.
