Four-legged wooden dining chairs use a 100% rubber wood frame to create a stable base for everyday meals, with each chair supporting up to 330 lbs. The 20 x 16 in upholstered seat is filled with high-resilient sponge so it stays comfortably plush through long conversations. A polyester fabric cover keeps the seating surface cool and comfortable as you sit. The 20-in high curved backrest follows the line of your spine to provide ergonomic support. A 19.5-in seat height works well with most dining tables for relaxed posture.
