Comfort	Siena means comfort. Comfort that helps you forget about the worries of the day. Comfort that tells your body, “relax, it’s time to recharge”. Comfort that helps you enjoy a long, deep, and soul nourishing sleep.	Our unique blend of foam and innerspring core make for a mattress that allows airflow and sleeps cool all night long. Unlike all-foam mattresses, the Aviya hybrid mattress provides core support using an innerspring system where each individual steel coil is wrapped in its own fabric pocket. Springs provide "active support" versus the passive support of foam, literally pushing back to support your body. The result is a more responsive sleep surface with greater comfort no matter what position your body may move to throughout the night. With 800 coils (in queen size) and a full 8" spring depth, our innerspring system provides deeper and more substantial support than the lower quality linked spring systems or 2-3" tall "micro" coils found in other innerspring mattresses.
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.	3" of foam surrounds all edges of the mattress so you can sleep edge-to-edge on the aviya, making our mattress feel bigger than the competitors. We use a perfect blend of high-density foams to provide both comfort and support. This type of high-quality foam is unheard of in almost any mattress, let alone at our prices.

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.

Can I use a heating pad with the Aviya Mattress?

Yes, it is safe to use a heating pad with the Aviya Mattress.

Do I need to flip my mattress from Aviya?

Does the Aviya Mattress have a break-in period?
