One control knob allows users to raise and lower the arms effortlessly.

• Optional flip-up arm can be adjusted to varying angles with a single knob
• Arms can be raised and lowered in infinite positions, and can be rotated left or right
• Adjustable levelers on all four legs allow the chair to sit solidly on an uneven floor
• Vinyl seats/arms are mildew resistant, sulfide stain resistant, and static dissipative

The optional Tray and Drawer assembly attaches directly to any chair's straight arm. The straight arm is pre-drilled for easy installation.
