Abstract

A multi-position body support, commonly known as a stander, supports a user in either a prone or supine orientation at any position from a substantially horizontal position to a substantially standing or vertical position. The multi-position body support comprises a tubular base having dual lock caster wheels for easy moving and positioning of the stander. A vertical support assembly, pivotally mounted to the tubular base, comprises a foot cylinder, knee support frame and a height adjustment frame. A foot support is mounted to the foot cylinder, a knee support is mounted to the knee support frame and a hip support, a trunk support and a head support can be mounted to the height adjustment frame. A padded strapping system secures the user within the pads and to the vertical support assembly. The foot supports can be rotated to aid in orienting the user in the prone or supine position. A pneumatic shock assembly connects the vertical support assembly to the tubular base frame and comprise a lockable pneumatic shock provides for urging the vertical support assembly from a horizontal position to a vertical position. A pedal is provided for unlocking the shock to adjust the angular orientation of the vertical support assembly in relation to the tubular base frame at any desired position between the horizontal and the vertical. A separate moveable tray is supported on dual lock caster wheels for use with the stander.
