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).

This mattress is the best ever

I am so in love with my eight mattress. It's super comfortable and I sleep so soundly every night on it. I look forward to getting into bed every night. No other mattress can compare. My other mattress was very expensive and it's sitting to the side right now because this one is the best!

Medium firm as promised

had doubts before pruchasing because I couldn't tell if I would enjoy the firmness. But it is truly a medium firm as promised. very comfortable...

Really comfortable, and so easy to setup. Was impressed because usually smart devices are a bit cumbersome but this bed was a breeze to setup and it's a very nice addition to my techy apartment.

Wouldn't trade it for any other bed!

I tried a couple other brands before settling for the Eight mattress and I wouldn't change it for anything. I'm a side sleeper and other mattresses gave me a hard time on my hips. This has been the best so far. I'm sticking with it!

Deserves an award

what a surprise to see finally real technology for sleep. No more of that bullshit that promises innovation and its just pieces of the same ol' foam. Eight is making the future of sleep and I was impressed to see how many new features they have released in the past months. Keep 'em coming

Supportive and cool

This mattress is the best I've tried so far. It looks very simple so I was scared that it would be low quality but actually in its simplicity it stands out because it is all about the comfort not the looks. And the tech is a great innovation. I had never tracked my sleep before and I have discovered that my room temp is higher than suggested and have been adapting it so I can sleep better. Interesting little fact..

Best sleep ever

I was suffering from back Problems and needed a bed to support my back, and after sleeping in the Saturn+ I felt great every morning, no more pain and I'm happier than ever. Will definitely recommend it to anyone.

Product satisfaction

"One of my goals it to sleep better. I love that without any wearable, I can track my sleep habits and run experiments to help me get a better night sleep. The smart alarm, relaxation sounds and mediation series are pretty cool too. I also love the warming feature for my wife's side that doesn't have to happen on my side. It sleeps right down the middle, not too firm and not too soft. Would definitely purchase again. Thanks!"
