There are a few common fillings for cushions:
- Feathers and downs. They puff up well. You might be allergic.
- Wool. I have a nice British supplier for wool cushions – they are stuffed more tightly than foam or feathers.
- Foam, obviously. This is for seat and back cushion, usually wrapped in ‘wadding’ or ‘stockinette’ that stops the foam from pilling.
- Polyester. It’s the cheapest, can become a little lumpy after a while.
