Down cushions
The caring of your cushions is important for how your furniture will last. Many of our cushions are turnable and it is important to turn them around often. Down cushions demand more caring because the down will be packed while using the furniture. It is important to pound in air to keep the cushions nice and elastic. 
Polyether cushions
Polyether cushions are the most sustainable cushions. If the are turnable, do so as often as you can.
