A 5" thick twin xl size mattress featuring an organic cotton damask fabric outer quilted to Ecowool batting and a 4.5" Extra Firm or Firm Natural Latex Support core. 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 4.5" Extra Firm or Firm rubber core gives this mattress an incredibly firm feel. This mattress would be optimal as a guest bed, but is not recommended for a permenant adult bed due to it not being supportive enough for such a purpose. 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.
