If you have an older HÅG office chair H04 4200, you can order new foam here.
Please note that the foam only fits chairs produced after 11/7-2006. Chairs made before this date have a different design on the seat.
The foam may look nice, but especially the seat may have flattened over time.
It may be better to order a complete set of seat and back, including fabric. You'll find that further down the page.
Production date on the chair and model.
