Funaction f.Cushion is a seat cover designed by Tetsu Kataoka that you can pump up with air to make it as cushiony or supportive as you like. It’s designed to help improve your posture while seated.
The fabric is made from 100% recycled PET bottles. Each woven meter uses seventeen recycled PET bottles (0.5L). It is also waterproof.
