Welnax OrthoSoothe Seat Cushion

A contoured memory-foam seat that stops your tailbone taking the drop. Two raised pads carry your sit bones and an open channel runs between them, so your weight lands where bone can take it — not on the one bone that can't. Low front edge so you don't ride up off your desk, a grippy base that stays put, and a detachable cover you can put in the wash.
