Certifications

Mattress contains a fire retardant barrier to comply with regulations. This material, otherwise known as an FR sock, is a fabric that encases our materials. It helps to smother and subdue a potential fire from spreading. Each of the four foams are CertiPUR-US certified. They meet program standards for content, emissions, and durability, and are analyzed by independent, accredited testing laboratories. CertiPUR-US approved foams are: made without ozone depleters, PBDE flame retardants, mercury, lead and other heavy materials; made without formaldehyde, phthalates regulated by the Consumer Product Safety Commission; have low VOC (volatile organic compound) emissions for indoor air quality (<0.5 parts per million).

It's a no brainer
Comfortable bed plus tech features! I mean, who wouldn't? I had just purchased another brand but then I saw this and said c'ommon! I gotta have it. It was a great deal too. so far I'm quite pleased. Highly recommend it.

Comfortable + amazing tech
This mattress really has it all. They are knocking it out of the park compared to every other mattress you can buy online. It's affordable, comfortable, has technology that is super cool to see how you sleep. I'm enjoying it every night and can't wait to see how it progresses with more software features.

Finally a sleep innovation
This product is really innovative, finally someone doing interesting things in sleep and not just boxing a bed. I recommend it to all my friends because it's not only a great bed but it also lets you know how you sleep and why you sleep that way. Enjoying it so far.

Awesome technology
I checked a lot of reviews before buying and this was the only mattress with technology. It is so cool to have the same comfort of other mattresses (I tried Casper and Leesa) and sleep tracking and warming.

I tried other 4 foam mattress before this but this one has the same comfort, a cheaper price and all the technology. No brainer
