CA King OMI Organicpedic customizable duo mattress. 100%-Natural Rubber Latex Mattress. Like new.

　　The OrganicPedic Duo mattress provides dual sleep zones and has three individually sleeved layers of premium 100% natural rubber surrounded by certified organic cotton, available in many different comfort options. The sculpted surface of the top layer provides the ultimate in comfort and pressure-point relief. This mattress has a removable cover and dual-zone internal layers that can be customized to accommodate each sleeper's preference.

　　We have 3 firm layers, 1 medium, 1 soft, and 1 extra-soft in addition to the sculpted top layer to allow for many customizable options. Only 4 layers are needed, but you can have all six layers to figure out the comfort level that you want. The mattress has only been used since April.
