| 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 Green Tea Memory Foam Mattress begins with our proprietary green tea and charcoal infused memory foam, because we’re fanatics about finding the sleep-enhancing qualities of natural ingredients. And boy, do these ingredients work! |
| 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. | Precisely layered CertiPUR-US certified foams allow you to sink into this mattress just right, for a supportive feeling that cradles your achiest joints and aligns your spine. Open air pockets in the middle layer of comfort foam encourage airflow so you don’t overheat, and they also add extra comfort beneath areas that need it most, like the shoulders, hips and knees. |

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.
Zinus Green Tea
Why do you use Green Tea extract in your foam?
Green tea extract is utilized in our foam because it is a safe and natural ingredient that helps to keep the mattress fresh, enhancing your sleep experience.
What does pressure relief foam do?
Pressure-relieving Z:Base foam is designed to eliminate pressure points, allowing you to wake up with fewer aches and pains. The foam adapts to your body, allowing your bones and joints to sink into softness.
What's the best kind of base for this mattress?
Our mattresses are designed to be low maintenance. They can be used with a box spring, platform bed frame, slatted base, bunkie board, or adjustable bed frame. For additional support, we recommend using a flat surface.
