How thick should the seat cushion be on a drafting chair?

For comfort during extended sitting at a counter-height workstation, seat cushion thickness of 3"–4" of high-density foam is recommended. Thin cushions (under 2") compress quickly under body weight and cause discomfort within an hour. Memory foam and contoured foam seat pans distribute pressure more evenly than flat foam pads. Waterfall seat edges (rounded front edge) reduce pressure on the back of the thighs. OfficeFurniture2go.com can confirm cushion construction for any model in our catalog — call 1-800-460-0858.
