Our cushions are so comfortable for an all natural organic option for your futon, couch, chair, RV...
We make these with layers of organic latex and cover with a zip on removeable, washable organic cotton outer. 
You can supply us organic cotton from organic cotton plus if you don't like our available options. 
 
1", 2", 3", 4", 5", 6"
 
We can make these with more than 1 layer so you can have firm with a softer top for more comfort. We can also add a breathable layer of wool insulator if you like. That option is on another listing. 
 
Our 4" and 5" will be 2 layers (they can be 2 different firmnesses). Others have optional 2 layers ability (ie the 6" king can be 4" of firm and 2" soft top). 
 
We have Dandelion, Khaki, and Natural Twill (all organic cotton)
 
We use a tight teeth nylon zipper with natural metal head. This is our 1 zipper on the long side of the cushion. If you want it 3 sided, let us know. Most seem to prefer 1 sided zip on the back side so it does not show. 
 
We also make these for window seat cushions, baby cushions, pet beds and more.
