These reclining chairs have a seat and back that can independently articulate with ease - even when the user is in the chair! Four positions: 45°, 60°, 90° and 180°. The seat has full head and trunk support. The strong, mesh vinyl sling drains well and can be removed easily for washing. Folds flat for easy handling and storage; lightweight, rust-proof construction. Available in three sizes, from pediatric to adults. Optional base extension raises the user 9" from the floor for easier use. All chairs come with nonslip rubber tips.
