Four-legged wooden dining chairs use a rubber wood frame to create a warp-resistant, splinter-free structure for everyday meals, with each chair supporting up to 330 lbs. The 20 x 16 in upholstered seat is filled with high-resilient sponge that compresses gently, so you stay comfortable through long dinners without bottoming out. A polyester fabric cover stays cool against clothing, while the 20-in high curved back cradles your spine and helps you sit upright.
