OSO Mattress

OSO Mattress

* Required Fields


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.

Woah, Best sleeps ever
I've had probabaly 7 different mattresses in my life and this has been the greatest! I wake up feeling refreshed and not sore like I'm used to. It's quite an upgrade! Thanks Oso!

Amazing Comfort and Value
The OSO mattress is extremely comfortable - it is nice and soft yet still supportive. I like the removable/washable cover, which will make it much easier to clean when needed. I would highly recommend trying one and would not hesitate to buy another the next time I need to replace or upgrade a mattress!

Two Thumbs Up
This is a great mattress. This is my second foam concept mattress. I will never go back to the traditional box-spring style. It really provides support where it is needed most. I would highly recommend.

Happy Guests!
The mattress arrived ahead of schedule in a box that was smaller than I expected. The sales person I spoke to when buying the mattress told me that we should move the box into the room before opening it. We put the mattress in our frame on top of the box spring and as soon as we cut into the plastic the mattress started expanding. The vacuum seal is unreal on these things! Within two minutes we had a regular size mattress. This mattress is absolutely perfect for our guest room! When I called my mom to ask if she preferred a hard or soft mattress for her visit she was grateful to have a choice (she picked soft!). Thanks OSO!
