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 materials come from nature - whether it be wool sustainably sheared from New Zealand sheep or latex tapped from trees. These premium materials are comfortable on your body and conscience. 100% all natural & organic Birch Wool provides unparalleled comfort and temperature regulation. Birch Wool is designed to retain shape with a natural elasticity of each fiber. Talalay latex is up to 7 times more breathable than other types of latex. Natural latex is also hypoallergenic and anti-microbial.
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.
We spent countless hours finding the right density of latex, quantity of wool, and type of steel springs to provide unprecedented comfort and pressure relief. Each mattress features a reinforced perimeter for best in class edge support. The coils that run along the outside of your mattress are actually firmer, so no more feeling of falling off the bed when lying down or sitting on the edge. Natural Talalay latex provides response to cushion your pressure points while giving support. Our latex is carefully managed to ensure consistency. Hundreds of individual steel coils help to cradle your body and provide support, while also limiting motion transfer. Additionally, the reinforced perimeter coils provide best in class edge support.
