A 7" thick Queen mattress featuring an organic cotton damask fabric outer quilted to Ecowool batting, some Organic Cotton Padding, and an Untreated Steel Innerspring Inner. Wool is used in the quilted outer for a variety of reasons including its natural temperature regulating properties, natural fire retardant properties, and its bacterial resistance. The innersprings are the support of the mattress and have a very firm feel. This mattress will work well on any slatted frame base or one of our organic foundations. Spot clean only. Spot clean using 1 part natural cleaner or vinegar to 2 parts water. This item is made to order and ships out within 1- 2 weeks from when the order is placed. Made here at our San Diego, CA Facility.
