A footrest is designed to support your legs from the feet upwards, thereby relieving your thighs and allowing you to sit comfortably at your desk for long periods. It helps improve posture and circulation by keeping the feet and legs elevated. It reduces muscle tension and fatigue by supporting the legs at an optimal angle. You achieve an ergonomic working posture by creating a 90-degree angle in your knee. The upper legs are horizontal and the lower legs vertical, reducing muscle tension.* Solid footrest with non-slip rubber surface.* Made from high-quality materials.* Tray dimensions: 40 x 30 cm.* Tilt adjustment between 6 and 25°.* Height adjustable in 4 positions: 80-91-120-128mm
