ABSTRACT:
A foot rest is provided with a platform that can be vertically adjusted and tilted by the user using only their feet. The foot rest includes a base with a support, a tilt column that cooperates with a locking assembly, and a platform. The locking assembly can be actuated by the user's foot to vary the vertical height of the platform. The platform is slidably engaged to the tilt column to allow the user to vary the inclination of the platform from the horizontal independently of the vertical adjustment.
