This handcrafted Organic Cotton Extra Firm Mattress is 6" thick and made with the finest natural, chemical-free ingredients available. Made in the USA with Organic Cotton batting fill and covered with Organic Cotton Twill.

This mattress is FIRM and offers firm hip and spine support. It's made without springs, so it won’t transfer motion between sleepers. You can place it on a box spring set or platform bed, or even use it as a floor bed.

Cotton is pure and natural, is hypoallergenic and will not off-gas like petroleum-based synthetics, so it is perfect for people with chemical sensitivities.

Prescription Requirements

You will need the following to have an all-cotton mattress made without chemical flame retardants:

A note on a formal prescription block or official doctor's letterhead with DEA number and should read to the effect of: "My patient requires a chemical-free mattress". It is very important that the DEA number is included. For legal reasons, we cannot accept notes from practitioners who cannot dispense medication, which includes a number of chiropractors, acupuncturists, and naturopaths.

All mattresses must pass flammability standards. Having a doctor's prescription allows us to make an all cotton mattress without chemical flame retardants. Mattresses wrapped in wool meet the flammability standards since the wool naturally retards the flames, so this is an excellent alterative to an all cotton mattress.
