These beauties are stuffed to the brim with wool, alpaca, cotton, and tencel scraps from the mill which are sandwiched between 2 layers of felted bats made from wool and alpaca. They are sewn into an organic cotton sleeve and then tufted to prevent the cushions from becoming flattened out with use. The cushions come with a slipcover sewn from a heavyweight organic cotton canvas that can be removed for washing. You can also over dye the fabric.
