This mattress is made with the simplest of materials for those trying to avoid toxic chemicals. The GOLS certified organic latex cores are 3" of soft,  then 3" of Medium, and 3" of Firm. This comes with the 9" zippered certified organic cotton damask or organic sateen outer which you zip the cores into. You can add anything on top of the mattress or just put a sheet over the mattress. 
 
This makes a simple pure mattress. Choose the damask or sateen outer fabric.
