The Nolah Mattress also sleeps cooler because Nolah is 100% temperature neutral and made entirely without the use of heat-trapping viscoelastic chemicals. Cooling Nolah AirFoam The top 2" of this cooling foam mattress is not temperature sensitive, unlike Memory Foam, so it sleeps cooler and contours better to your body.
Support	Some people love super soft mattresses. Some people love a rock hard one. Most people are somewhere in the middle. That’s why the Siena is a medium firm mattress, comfortable to sleep on, but also firm enough to correctly support your body.	The Nolah Mattress is scientifically proven to provide 4X times less peak pressure on the hips, shoulders and back area compared to high-end memory foams. With a supportive bounce and zero motion transfer, you're are guaranteed to enjoy a deep, restorative sleep every night. Supportive Avena® Foam 1" support layer that's stronger and more durable than Latex. It also provides a healthy and responsive bounce to keep you sound asleep all night.

FAQs

Siena Memory Foam

What are Siena mattresses made of?

The Siena Memory Foam Mattress is made with a tri-layer design that includes gel-infused memory foam and two different types of polyfoam. The foam used in the mattress is CertiPUR-US certified, meaning it's free from harmful chemicals and additives.

Can you flip the Siena mattress?

The Siena mattress is not designed to be flipped. It has a high-density base foam layer at the bottom, and flipping it would compromise its pressure-relieving properties.

How long will the Siena mattress last?

The Siena mattress, being a budget mattress, is not made with as many high-quality materials and is therefore expected to last about five years. This is approximately half the lifespan of a typical mattress.

Nolah Original

Can you flip the Nolah Original mattress?

No, the Nolah Original mattress is not designed to be flipped. It should be used with the base layer at the bottom and the AirFoam on top.

What if I don't like my Nolah Original mattress?

If you are not satisfied with your Nolah Original mattress, you can return it for a full refund. However, you should try the mattress for 30 days before contacting the company for a return.

Is Nolah a good mattress?

Yes, the Nolah Original is a highly-rated mattress. It is a soft, pressure-relieving mattress that is a great fit for side sleepers and those with pain issues.
