Designed to ensure comfort through all 18 hours of Wagner’s Ring Cycle or simply eight hours at a desk, this adjustable chair’s cushioned seat is wider and deeper than that of a standard folding chair, and its tubular 16-ga. steel construction provides stability on any type of flooring. Whether perched on the front edge of the seat to play the French horn or leaning back while on the phone at work, this ergonomic chair helps prevent slouching thanks to a padded backrest that supports the thoracic spine and a gap above the seat that allows the lower back to curve and protrude naturally. The backrest and legs also adjust in length so users 5' to 6'5" tall can keep their feet flat on the ground. Folds flat for storage. Unfolded: 40" H x 21" W x 20" D. (24 lbs.)
