A seat cushion turns any chair into a comfortable one — the right one supports your tailbone, improves posture, and makes 8-hour desk days bearable. Here are 10 worth buying.
My top pick: A memory-foam seat cushion with a coccyx cutout, a non-slip base, and a machine-washable cover, is the one to own — memory foam contours to your body, the coccyx cutout relieves tailbone pressure, and a washable cover keeps it fresh.
