20-06 is a sleek new chair featuring an ultra-slim, all-aluminum frame, tempered for strength and hand made at the historic Hanover Pennsylvania factory using Emeco's proprietary "77 step process". The ergonomically shaped aluminum seat and back are hand welded, resulting in a minimal, seamless appearance. The 20-06 chair is super strong, yet uses 15% less aluminum than the original Navy chair. Of that metal, 80% is recycled aluminum, qualifying it as an environmentally sound product. 20-06 armchair does not stack. Seat & back pads are offered in black vinyl. Suitable for outdoor use.
