I’m really impressed with this Queen Mattress. It arrived neatly packed and expanded quickly with no strong odor. The medium firmness is perfect, supportive enough to help relieve my back pain while still feeling comfortable and cushioning. I also sleep hot, and the gel foam actually makes a noticeable difference in keeping the mattress cool through the night. The removable, fiberglass-free cover is a big plus for peace of mind and easy cleaning. Great quality for the price, and being CertiPUR-US certified makes it even better. Highly recommend!

Honestly, I was pleasantly surprised by this mattress. It has a medium firmness that feels very comfortable—not too hard and not too soft. I’ve been sleeping better since using it, and my back definitely feels better in the mornings. It also stays cool during the night, which is a big plus for a memory foam mattress. I really like that it’s fiberglass-free and CertiPUR-US certified, which gives me peace of mind. It arrived neatly packed in a box, was easy to set up, and expanded quickly. The removable cover is convenient and easy to wash. Overall, it feels well made and is a great value for the price. I would definitely buy it again.

Oh my goodness yaaaaaas!!!! Bought a different bed bout a month ago and it was NOT it! So did some more searching, and aloooot of review reading. I went with this because reviews addressed it was actually FIRM. And boy, yes it is! It has a nice layer of memory foam on the top just enough to give you that ahhhh feeling when you lay down. But then, the firm foam beneath takes it from there with such lovley support. I am so picky about my bed and buying online was tricky, but this has been a great buy. I actually slept on the cooler side, finally! Just enough give to hug you, but enough support to not feel like you woke up in a crater. There was no sunk in spot when I woke up, and bitty indent that was there puffed right back up. All in all if you actually like a more firm bed, this is it! It has good edge support too, which was so nice. The motion part worked very well too, I didn't feel my dogs up and down all night get in different cozy spots. They actually snored pretty good on this bed. 5 stars all the way! No smell. Good edge support. Good sleep support. Very impressed, and that's hard to do with a online purchase. Very well made fathom. Thank you from my back.

It provides good support and has helped reduce back pain. There is no uncomfortable sinking, and the mattress maintains its shape well. Heat retention is minimal, so it stays comfortable throughout the night. Motion transfer is also very low, making it a great choice for restful sleep. Overall, excellent quality and value.

We found it to be very firm. Too firm for our tastes. We ended up adding a 1.5" memory foam topper and a quilted mattress pad. After those additions it was super comfortable.

I bought this for my son and have completely taken over his bed. The mattress arrived in a fairly small box compressed. It didn’t take long after opening for the mattress to expand. It was easy to set up. And for someone that is 9 months pregnant and even sleeping has been uncomfortable and painful.. The mattress itself is extremely comfortable and has helped me to sleep through the night! This is the perfect medium mattress that is supportive but not too hard and not too soft. It has been amazing and I’m not waking up from hip and back pain anymore. It also is very breathable and not like other memory foams that retain a lot of heat.
