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 top layer, the ThermaPhase comfort layer, is the culmination of years of development. Our comfort layer combines two different phase-change materials that target temperatures on both ends of the optimal sleep zone. Upon reaching an ideal sleeping temperature, the phase change material undergoes a molecular transformation that works to maintain the temperature at the optimal level. This results in a mattress that will keep you cool when its warm, and will help keep you warm when its cold. There is not a more technologically advanced, or more comfortable mattress available, period. Our ThermaPhase comfort layer, is the culmination of years of development. We combined two different phase-change materials that react to temperature fluctuation. The result is a "Smart" mattress that will react to heat and actively cool the sleeping surface. OR if sleeping conditions become too cold, the Thermaphase molecules will redistribute absorbed heat to help keep you warm.
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.	Each layer was engineered with varying levels of density and weight capacity to provide dynamic support. Our top 3 layers are a patent pending hybrid-foam package that we call Z3. The Z3 package utilizes various pressure ratings that only engage when necessary, providing the right amount of support and comfort for any size user, and optimal pressure point relief for back and joint pain.

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.

Zotto

Do I need to keep the box in case I decide to return the mattress?

No, you do not need to keep the packaging to take advantage of our 100-night guarantee. If you decide to return the mattress, we will arrange for it to be picked up from your home at a convenient time for you.

Should I use a mattress protector on my Zotto?

While not necessary, a mattress protector can be used on the Zotto for extra protection. It can make the mattress feel slightly firmer, which some people prefer. The Zotto cover is also removable and machine washable.

How thick is a Zotto mattress?

The Zotto mattress has a thickness of 10 inches.
