    • Quality mattress for the price
Color: Charcoal Slate Size: Queen (U.S. Standard) Set name: 14 In Medium Firm
Review Image by Sara holloman
Super comfortable. Is firm but soft enough that when I sleep on my side my hips don't hurt. Its very tall because my bed does not require a box springs so it's not too low to the ground. The edges aren't as firm as they appear in some of the pictures they definitely swoop down when you sit on the edge. Its quiet and you don't feel the movement on every side when you move and for the price you really can't beat it. It stays pretty cool. And it requested 48 hours to expand but I feel like after 24 it was well expanded. ... show more

    • Coma inducing comfort
Color: Cerulean Size: King (U.S. Standard) Set name: 12 In Medium Firm
This is by far the most comfortable bed I've ever owned. Not even joking. I got the best sleep I've had in years and my back didn't hurt and still doesn't hurt after sleeping on it. It's soft and I feel like I melted into a cloud. This over any name brand mattress ANY DAY! FANTASTIC QUALITY! It's big enough for me, dad and a kid or two (you know kids, sometimes they crawl in bed in the middle of the night) I could be dead asleep and don't feel dad getting into or out of bed. Literally no movement or disturbances. I'm lucky I didn't fall into a coma. Highly recommend and would buy again. Might even buy it for my mom<3 ... show more

    • Amazing product and price!!!
Color: Charcoal Slate Size: King (U.S. Standard) Set name: 12 In Medium Firm
I was happily surprised at the quality and feel of this mattress. It uncoiled out of its plastic tube into an excellent thick, king-size. Very comfortable and strong sides. Amazing product at an amazing price!

    • Good Value Mattress for the Price.
Color: Cerulean Size: Queen (U.S. Standard) Set name: 12 In Medium Firm
This is a great mattress for the price. We needed to replace my daughter's mattress and did not want to spend a fortune on it. This is very high quality mattress and love the 12 inch thickness. Its soft and quite comfortable. My daughter loves it but I personally think it should have been little on the firmer side. The initial setup was also fine as it expanded within 12 hours. ... show more

    • Pretty comfy!
Color: Charcoal Slate Size: Full Set name: 12 In Medium Firm
Review Image by Thomas
At first I didn't think that the box that came had the right mattress in it, because it wasn't really that large. It was really heavy though, so I dragged it inside and opened it up. It comes super tightly rolled up and vacuum sealed, and when I cut open the plastic, it started inflating and puffing up right away. (Make sure to only open this thing up in the room you want it in, and give it plenty of room!) Sure enough, yea, it was the full size i'd ordered. I have no idea how they roll these things up so tight. Anyway, first night sleeping on it, it was a bit more firm than I was expecting, and I was unsure of it. Second night though, it'd puffed up all the way, and felt quite a bit better. They aren't kidding when they say that these things need a couple days to fully expand. Best nights sleep i've had in quite a while. Good stuff. ... show more

    • Good quality for the price
Color: Charcoal Slate Size: Full Set name: 12 In Medium Firm
I got this for my six-year-old daughter who needed an upgrade with her mattress and this did exactly that very comfortable. We waited the full 24 hours as suggested for it to inflate and she loves it. It’s the perfect amount of medium plush. We also added a pillow topper for added softness
