Siena - "Best sleep ever!"

“I did a lot of research before buying a new mattress, and I believe this mattress was definitely the best for the price. No more shoulder, back or back pain. And setup was easy!”
Dawn B.Verified Buyer

Oki Oki - "Not what we expected"

Too firm even though it is called soft. The only thing soft about it is the borders which collapse whenever you get close to the mattress edge. Will be looking to return.”
Tyler B.Verified Buyer

The problems with Oki Oki

More Money, Less Mattress?

That doesn’t sound like a good deal to us! OkiOki’s lowest price model costs more than Siena, but it has less comfort layers. So the question is…

Why settle for fewer layers and less support?

Siena is made of 5 different components, including three different kinds of foam. OkiSoft only has three components with two different foams. It’s only rated a 5 on the firmness scale, so don’t be surprised if you sink in and feel less supported.

The Siena Mattress

Siena Layer

Soft, Durable Cover

Our cover is soft to the touch and breathable to keep you cool and comfortable.

Responsive Gel Memory Foam

This 2” layer of pressure relieving gel-infused memory foam adapts to your unique body shape and size, while contouring to your curves.

Support Foam

Four inches of convoluted foam further cushions your body, giving you just the right level of comfort and support. Ripples in the foam allow for enhanced airflow.

Foundational Foam

This sturdy 4” stability foam layer is strong, durable, and allows the comfort and support layers above to work their magic.

Shift-Resistant Lower Cover

The durable lower cover keeps all of the mattress layers perfectly in place and prevents shifting.

OkiOki Mattress

Ice yarn cover

Their cover is hypoallergenic, but wouldn’t you rather one that keeps your bed bacteria-free and fresh?

Cushioning memory foam

3 inches of foam may sound good, but the OkiSoft lacks the comfort foam layer Siena has.

Transition layer

7 inches of PU foam makes up the bottom part of the OkiSoft.

It’s time to sleep on a Siena…

“This Is Quite Simply A Stunning Mattress At An Impressively Low Price.”

Not our words. That’s the conclusion of “Slumber Search” after a rigorous test of the Siena mattress. You see, instead of trying to take more of your money, we focus on giving you a great night’s sleep at a fair price. The experts and everyday folk agree, the Siena is one seriously comfy mattress.

Top mattress. Low price.

Instead of wasting money trying to reinvent the wheel. Or come up with marketing gimmicks to get you to spend more money. We focus all our time on the things that really matter.  That is, designing a really comfortable mattress that correctly supports your body. Manufacturing it to really high standards. Making sure the ordering and delivery process is smooth. And keeping the cost as low as possible for you.

Great sleep. Made easier.

Getting a new mattress shouldn’t be hard work. It should be easy to buy, test and return a mattress. And it should be risk-free and stress-free for you. That’s why you get a generous 180-night home trial, so you have time to really test it out. That’s why you get free shipping and returns, because you shouldn’t have to pay while you make that decision. And it’s why you get a 10-year warranty, without the annoying small print.

Real service. Not just a lip service.

Good customer service doesn’t happen by accident. That’s why we work hard to give you a great experience. But we also know a happy person on the phone doesn’t make up for problems with your order. So we invest in technology, logistics and people to make sure everything runs smoothly. Because while a smile is nice, we know a great product delivered on time is a better way to make you happy
