Four-legged bentwood frames with a metal bracket give these chenille fabric upholstered dining chairs stable support for everyday meals or study sessions. The enlarged ergonomic backrest has a curved design that follows the line of your spine so you can lean back comfortably. A 17.5 x 16 in seat filled with high-density sponge distributes your weight across a larger area to reduce pressure during long sitting. An X-shaped frame under the seat reinforces the structure to support up to 330 lbs without feeling flimsy. Adjustable foot pads at the base let you fine-tune each leg so the chair stays level and steady on slightly uneven floors.
