A 7" thick Twin XL mattress featuring an organic cotton damask fabric outer quilted to Ecowool batting and the option of one 3" Extra Firm or Firm Natural latex core and one 3" Extra Firm, Firm, or Extra Soft Natural latex 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 various firmness of the cores give a more customized feel than your average 6" rubber mattress without compromising support(unless you choose an extra soft as one of the options which is not recommend for adults on a permanent basis). This mattress can be medium firm to extra firm depending on what you choose, it would be good for back or stomach sleepers. Side sleepers should consider checking out the leo for an extra firm option or the sagittarius while choosing firmer core options for a medium firm option. The different layers inside this mattress can be taken and moved around due to the outer being a zip outer. 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.
