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.

My arms are no longer numb when I wake up!
I have had major numbing in both of my arms while I sleep since 11 years ago. I awaken numerous times a night and have to reposition my arms so they will wake up. My husband and I received our OSO mattress a few months ago. The first morning after sleeping on this mattress, I woke up and realized my arms were not numb. Every night since then has given me the same results. I am so happy to finally sleep and not have the numbing issues I was having. I just can’t believe how much of a difference a mattress would make. Thank you!!!

OSO many Z's
My husband and I have been sleeping on our new OSO for a couple months now. The setup was super simple. The mattress is supportive yet soft. Our favorite part is that we don't disturb the other person when moving/shifting! So glad we invested in quality sleep.

Very Comfortable
I really appreciate the option of using the soft or firm side of this mattress. I prefer the soft, and find it very comfortable to sleep on. My wife and I are able to move on our side of the bed without causing much noticeable disruption to each other. We are very impressed with our new OSO mattress, and are very glad we made the purchase..

Take a chance
We love our OSO Mattress. We bought it after reading a friends review and thought we would take a chance. We are so happy we purchased it. No other mattress has been this great, it offers support while still being soft and comfortable. Thanks OSO!

Love it!
This is the first mattress that I've ordered that was delivered in a box and I'm never going back. It was quick, free shipping, and I was able to open it and lay it out easily. I love how soft it is and how well I sleep every night! I will never go to another mattress.
