OSO Mattress

OSO Mattress


Not all foams are created equal


Latex Layer

1.5’’ of premium Talalay latex goes through a careful washing process so it won’t irritate sensitive skin. Plus, it’s naturally hypoallergenic, dust-mite resistant, and free of harmful chemical emissions.

Float Layer

1.5’’ of RevTechTM foam sets you up to float into dreamland. This layer is designed in tandem with the top latex layer to be breathable, cool, and promote air flow.

DreamCell™ Foam Springs

More durable than spring coils and the secret sauce to the comfort of OSO mattresses, our dream cells are crafted from pillowy latex for high durability and comfort.

RevTech™ Foam

Many foams are unfortunately a source of harmful chemicals, but our 6’’ RevTech™ support layer is free of heavy metals, formaldehydes, VOCs, and without dangerous off-gassing.

Top Knit

This impossibly soft gray waterfall cover zips off and can be dry cleaned.


Change your mind as often as you want

The OSO mattress stands out from the crowd because we give you both a soft and firm option in the same bed. Since your pressure points are concentrated in between your shoulders and hips, we zero in on the support in those areas. Simply rotate the bed 180 degrees to find your preference.

Extremely Versatile!
I've had my OSO now for over 7 months and couldn't be happier!

At first I was a little nervous purchasing a bed online. However, the 101 Night Promise helped me make the plunge! I loved being able to try out the bed in my own home to make sure it was right for me. I currently use the soft side, but knowing I can change over to the firm side if my preference ever changes is very comforting.

In addition, as a (somewhat) recent college graduate who is prone to moving every few years, the flexibility of the foam mattress and portability (being able to fold it and transport in my compact car) is also a huge plus.

Great bed
I usually wake up 1-2 times during the night. With this mattress, slept completely through the night. Materials look super high quality, love that I could fold it up to get it through doorways.

The best mattress I have own
I love the Oso mattress. There are some nights when I need to lay on the soft side and other nights when I need more support. I don't have to worry about needing a new mattress for different needs. The Oso mattress has also been very kind to my back after major surgery. I love it!

Amazing comfort and quality service
I've had a king size mattress for a few weeks now and this thing is amazing. I have never owned a foam mattress before and this is a great introduction. I love that you can choose what side to sleep on depending on how your body is feeling that day. Top notch!

Cheers to OSO!
I’ve never really had a comfortable mattress before so this has been one of the best decisions we've ever made! I’ve struggled with back pain for a few years and my pain has significantly been improved and I feel a million and one times better during the day!
