A 10" thick California King mattress featuring an organic cotton damask fabric outer quilted to Ecowool batting and an Untreated Steel Innerspring Inner with a 3" Extra Soft Natural Latex Topper on top. 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 steel innersprings give this mattress a good support while the topper adds a nice level of comfort. This mattress is on the softer side, though due to the innerspring bottom it still has a noticeable firmness to it. It would work well for those who are back or side sleepers and like a good amount of cushioning. 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.
