A 7" thick Twin size mattress featuring an organic cotton damask fabric outer quilted to Ecowool batting and one 3" Extra Firm or Firm Natural Latex core on one side and one 3" Extra Firm, Firm, or Extra Soft Natural Latex core on the other side. 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. If choosing to use this mattress with one extra soft core, then this mattress would be optimal as a guest or child's bed, but is not recommended for a permenant adult bed due to it not being supportive enough for such a purpose. If not using an extra soft core, then this mattress would work for all ages including adults and allows for the option of two different firmnesses to be chosen and customize the feel. Overall, this is a very firm mattress.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.
