Bentwood chairs are sturdy and comfortable seats, contoured to encourage healthy posture. Good posture improves circulation, helping one maintain focus and support productivity. These stackable chairs feature a vented back for air circulation and built-in handles to easily arrange. The one-piece design is crafted from birch plywood that is molded into a shape creating a durable natural hardwood, sealed with a UV lacquer to protect the wood surface and reduce scratching. Chairs feature smooth rounded edges, angled anti-tip rear legs, and non-scuff boots to protect floors and reduce noise. Easily clean by wiping down with a mild soap and warm water solution, and dry thoroughly. Designed for everyday use in daycares, preschools, and classrooms, and perfect for the home; maintenance-free chairs are fully assembled with no hardware to check or tighten. Bentwood chairs are green guard [gold] certified for low VOCs, CPSIA compliant, and meet or exceed the minimum applicable requirements of ANSI/bitmap x6.1, evaluating the safety, durability, and structural adequacy for educational seating. We are committed to safety, testing, and regulatory compliance to ensure our products meet or exceed industry standards. You and your kids deserve the absolute best for a brighter way to play, share, learn, and grow.
