Materials Overview
The Organic Latex Mattress is a mattress that has 4 layers of construction:
  • 100% Organic Cotton Knit Cover Quilted to Eco Wool

The Casper Original is good for sleepers of all kinds who want both support and cooling. Three layers of construction:
  • Breathable Polyurethane Foam
  • Zoned Memory Foam
  • Durable Polyurethane Support Foam.
Comfort Info
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.
A layer of Airscape™ perforated breathable foam increases airflow and circulates air so you don't get too hot at night.
Support Info
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.
Premium foam conforms to your body to relieve pressure.
Zoned Support™ provides a layer of memory foam with 3 ergonomic zones to help align your spine and provide more relief.
The durable base is engineered to prevent sinking and sagging while supporting your whole body.
Comfort Specs
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.
Stay cool all night with the innovative cooling system. AirScape™:
  • A top layer of perforated breathable foam helps reduce heat.
  • Tiny holes move hot air and body heat away.
Support Specs
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.
Get all-night comfort with the innovative support system. Zoned Support™:
  • 3 zones of targeted support for proper spinal alignment.
  • Softer foam around the shoulders provides more relief to the upper body.
  • Firmer foam under the hips, waist, and lower back helps align your spine.
Fabric Specs
The Select Sleep Organic has an organic cotton cover to provide a soft, breathable surface for your comfort. Cotton also provides just enough stretch so that your mattress is easy to assemble and that the cover stays taught. Polyester is never used in our covers. 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.
