An office chair is a piece of equipment most office workers use for hours at a time every single day. Sitting for this long puts strain on the muscles that keep the spine in the correct posture, overworking some while neglecting others. In time, this can cause degenerative changes. The circulatory system also suffers from excessive sitting. All this makes having a chair that promotes better posture and helps keep aches and pains at bay a worthwhile investment for most desk-bound professionals. Massage office chairs should be a requirement, not a perk!
