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.

Great bed
This bed is amazing!!! When it first arrived I unpacked it and laid down a few hours later (after passing out immediately on it) I moved it to my bedroom. I would and have highly recommend it to anyone!

Superior Sleep
My husband and I purchased our king sized OSO mattress about 2 months ago. We have been thrilled. The set up was simple and getting it into our condo (up stairs and around corners) was no big deal with the creative packaging concept. It also had no chemical odor when we unpackaged (which I was concerned/skeptical about).

We sleep on the firm side and both love it. It is as cool as it claims (no waking up with a sweaty neck and back). I also struggle with poor circulation and arthritis and used to wake up every night with limbs that had fallen asleep/very achy from the bends and pressure points of our traditional mattress.

I have had significantly less issues with the OS0 and feel comfortable highly recommending it for arthritis/back pain. When it's time to purchase again, we will stick with OSO and never go back to a traditional box spring.

Sweet Sleep finally
We are happy to finally have a mattress that is quiet, and comfy to sleep on. For years our classic mattress would bounce and make noise with every turn.
The OSO is like lying on a soft raft, supporting the parts that need it most. We like the "firmer' end now but anticipate switching to the soft end as we want- I enjoy options.
If you buy an OSO, buy sheets with regular pockets (not deep) for a smoother, unwrinkled look.

Great Mattress and good value!
Love the versatility of soft and firm. Moving it in was so great compared to moving out our old king (traditional mattress).
Overall we like the mattress a lot.

Incredible better than SleepNumber
Ive had a Sleep Number for years me and my wife like it. But... even with 20 levels you still particular for no reason feel like you are sleeping on an air bed at your moms house lol. We got a California King OSO, to replace the Sleep Number California King. This was a great decision, my wife was so in love she sleep through her work alarms. Its a great bed, id recommend it to anyone.
