Siena vs OkiOki: Mattress Construction

Siena comprises five layers with three different types of foam, and OkiOki gives you three layers with two different kinds of foam. OkiOki is only 5 on the firmness scale. So, you may find it too soft. Whereas with Siena, you get a 6.5 firmness level, which is medium-firm. It hits all the right spots for a comfortable shuteye. Both mattresses are 10 inches thick.

Material and Construction:

The topmost layer of the Siena mattress comes with an anti-microbial and breathable cover. It is soft, keeps you cool, and ensures the mattress remains bacteria-free! With OkiOki, you get a hypoallergenic top ice yarn cover. While it may help you combat your allergies, it doesn’t keep the mattress fresh or bacteria-free.

Layer two of Siena is made of plush body-hugging memory foam. It evenly cushions your weight, helps your whole body relax, and offers optimal pressure relief. OkiOki brings you a cushioning memory foam layer too. But it is a little too soft, and some may find that it lacks the comfort and support of Siena. Next, Siena brings you supportive comfort foam and this layer of denser polyfoam cushions your body for better comfort and support. With OkiOki, it’s the last layer and here you get transition PU foam.

With layer four, Siena moves towards support and this sturdy layer helps support your whole body, even if you’re a little heavier. Finally, you get a shift-resistant lower cover, preventing slips or skids, even if you jump on it. So, you can rest assured.


OkiOki is rated a 5 on the firmness scale, which means there are chances that you may find it a little too soft. In fact, you may also feel like it is unable to offer enough support leading to the feeling of sinking in. Siena, however, brings you a mattress rated 6.5 on the firmness scale. It is medium-firm and gives you excellent comfort and support.


Both mattresses come with 10-inch thicknesses.

Siena Vs OkiOki: Warranty and Returns

Both Siena and OkiOki give you a 10 years warranty. While Siena also offers free returns, OkiOki gives you simple returns. Cryptic much? Well, if you are planning to buy an OkiOki mattress, maybe, first contact customer service to check their return policies.

Siena Vs OkiOki: Size & Pricing

OkiOki claims to be the most affordable option, but Siena takes the cake. OkiOki has fewer layers and a higher price, whereas Siena gives you more at a highly affordable price. OkiOki’s lowest price model costs more than Siena. An OkiOki Twin mattress costs $400 and a Twin mattress by Siena costs you just $199.

Arrived a day after ordered, on a saturday.  Great packaging, easy to put out, fully extended after 2 days, very comfortable. But more for people who prefer firm beds. Doesnt sink in almost little to nothing which is my preference if you order the bottom piece from somewhere else you will need a box spring. And the thing that goes on the mattress comes off and is washable i did not know that a whole new plus!!!! If i ever need a bed this is where im coming too!

I love the capacity to take a quiz and order the mattress, the delivery and overall purchase was very easy and pleasant. I am noticing more back, knee and shoulder pain than before. I’ve had the OKISoft for about 2 months, so I am guessing I have the wrong mattress. I was really hopeful.

The bed never fully expanded. They sent a replacement and the replacement never fully expanded either. Some sections higher than others.

We bought an Oki easy and found it to be too firm for us and decided to put it in our guest room. We then bought the Okisoft thinking it would be better. It wasn’t softer. It seems as firm or firmer than the other and it feels confining. I have suffered shoulder pain that was not relieved, in fact made worse by this mattress. We recently spent a few nights with friends and slept on an old Serta. The pain disappeared. After the first night back on the Okisoft, the pain came back. The Oki easy has a nice appearance while the Okisoft has an irregular, even saggy appearance.

It looks like we have a clear winner: Siena. This mattress provides luxurious medium-firm comfort without burning a hole in your pocket. It is super affordable and incredibly comfortable. With OkiOki, you pay more for fewer layers and lesser comfort. Aside from this, it is nice that you get free shipping and returns with Siena. Both mattresses give you a decent trial window. That’s about it from our end. We hope you found this comparison guide helpful!
