Each hand-sewn cover is made of 100% organic cotton that has been quilted to Eco Wool. The 360° zipper makes assembly a breeze and allows you to replace and rearrange layers as needed, as well as remove completely for spot cleaning and airing out. Replacement covers are available.

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.	The wool in our organic cotton cover is premium Eco Wool, sourced from the Woolgatherer Carding Mill. Woolgatherer follows wool through every stage from the pastures to the finished product. Woolgatherer staff is meticulous about ensuring their wool supplier flocks are managed in a humane, chemical-free, and environmentally safe manner. Latex is naturally hypo-allergenic. Its anti-microbial properties inhibit dust mites, mold, and mildew from thriving. Because latex is a product of pin core construction with thousands of tiny air channels that provide natural ventilation. Mildew, staphylococcus and other bacteria can't live in latex foam, making it the perfect choice for allergy sufferers and anyone wanting to breathe, fresh clean air while they sleep. It keeps you warm in the winter and cooler in the Labor Day.
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.	Our Select Sleep latex mattress conforms perfectly to your body's contours and evenly supports the spine to provide optimal orthopedic support. We offer a variety of latex types including the world's finest latex process - Talalay. Latex instantly reacts and adjusts to changes in position giving the body maximum comfort and back support. Its unique ability to conform to your body alleviates areas of high pressure that causes you to toss and turn at night. Pressure Equalization Latex relieves pressure that causes you to toss and turn at night. The ability of latex to gently support and conform to your body alleviates pressure points and dramatically reduces tossing and turning. The latex mattress itself reduces pressure areas by as much as 90%, thus ensuring a sound and comfortable sleep.

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.

Sleep EZ Organic Latex

Do we carry any blended or man-made latex?

No, all of the latex we carry is made from 100% natural rubber from a rubber tree. The final product is 98% pure rubber, with the remaining 2% consisting of natural fatty acids, natural soaps, and natural reinforcing agents needed for manufacturing.

Can I wash the cover?

The cover is removable but not washable. It is recommended to spot-clean the cover with a mild detergent and a brush, then place the cover in the sun for disinfection. The cover cannot be machine washed, dry-cleaned, or hand-cleaned in the bathtub as it will shrink.

What type of fire barrier is in the mattress?

No chemical flame retardants are added or used in the mattress. The cotton and wool cover contains 1" of wool that acts as the natural fire barrier. This wool is also excellent at temperature regulation and wicking away moisture.
