We firmly believe that creating a new business isn’t just about turning a profit, it’s also about bettering the world around us. With this philosophy in mind, every aspect of our design and manufacturing process was meticulously chosen to minimize the environmental impact of introducing a new product into the market.
Our flexible polyurethane foams meet CertiPUR-US® program standards for content, emissions and durability and are analyzed by independent, accredited testing laboratories. Moreover, they are produced without ozone depleters, PBDEs, TDCPP, or TCEP flame retardants, and have Low VOC (Volatile Organic Compound) emissions for indoor air quality.

The latex used in our mattress constructions is certified to the Global Organic Latex Standard (GOLS), a new certification available to mattress manufacturers. Control Union Certifications (CU), a globally recognized organic certifier, developed GOLS based on years of experience certifying organic products in other industries, including foods and textiles. This certification ensures that all materials and manufacturing processes adhere to strict and specific global organic standards.
We build products in the United States to decrease transportation fuel and subsequent greenhouse gas emissions, and aim to deliver innovative solutions that evolve with you as your needs change. And, of course, our delivery boxes are made from recycled materials.

This is exactly what I hoped it would be. I needed an affordable not too soft not too firm mattress and this is perfect. I like that it is a combination mattress, because I find coils more supportive than just a foam mattress.

I just got the mattress earlier this week. The mattress is supportive and have a good feel. The only negative I can see is that it does sleep a little hot.

Awesome…I ❤ this mattress! I’ve had some of the most refreshing cool nights on my new bed. I think 4 of my friends have purchased this bed/mattress presently! Its truly Amazing!!??

I tried another online mattress brand before this and did not like it at all. It was an all foam mattress and slept very hot. I’m a bit of a bigger guy so I tend to sleep warm but I was extremely uncomfortable before. The Yaasa ONE has the hybrid springs which feels better for support and I don’t sink in. The top quilted Gel cover keeps me feeling great. Highly recommend this mattress.

This is the first time I bought a mattress online. I wanted a great quality mattress without being overcharged. The feel is amazing. The top has a familiar pillowtop feel but sleeps cooler.

I was not in the market for a mattress. I visited a friend in Los Angeles this past weekend and she had received this mattress in the mail. I didn’t realize how bad my mattress was until I spent on this and woke up feeling so much better. Already ordered mine!
