We receive a lot of requests for us to make cushions from our fabulous medical sheepskins, so we made one!
We paired it with our unbleached cotton canvas with hidden zipper on the back, with the intention that if absolutely necessary this cushion cover could be washed following the same procedure as washing our medical sheepskins.
It's currently stuffed with loose polyfill but you could also stuff it with washed sheeps wool or actual inner cushions 16" x 16". But we like the idea of loose filler so that the cushion can be adjusted to the comfort and height level required.
You should be able to fit a cotton cushion cover over this to keep it cleaner for longer and still get the benefits of the medical sheepskin.
