| 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. | Engineered to reduce pressure on your circulatory system the Plank provides for better blood flow - and better lower back support, compelling you to inhale more oxygen while you snooze. |
| 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 Plank offers a firmer, flatter, flippable surface for a neutral spine position that's better for your back and posture overall. A 2" layer of our firmest transitional TitanFlex foam adds deep compression support. A 7" high density base foam ensures durability and stability for the life of your bed. |

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.
