Rethink your desk posture with this kneeling chair that shifts your center of gravity forward for a more upright spinal alignment without the fatigue of a rigid sit-stand routine. Thick high-density foam pads the seat and knee rest for cushioned comfort throughout the workday, while a height range of 21 to 26.5 inches matches most standard desks. Locking casters let you roll into position and hold firm once you settle in, and a triangular reinforced metal base delivers reliable 220 lb support from a compact footprint.
