Covered Mattress Cores

Our natural rubber covered cores can be used to soften a mattress, XSoft or Soft, to create a trundle or guest sleeping surface Firm, XFirm, or Super Firm, or can be combined to create an inexpensive mattress setup. Just combine 2 or 3 cores to make your bed just like you want it. We recommend a soft top and a firmer base. Each core is covered in our organic cotton muslin fabric. You can buy a separate organic cotton cover to put your cores together or you can just buy these cores and put a sheet on top.
