The portions are formed of a solid, yielding support material, such as polyurethane foam. Preferably the support portions have a water proof outer surface.

An ergonomic work chair for activities requiring a bent-forward posture has the following features: a supporting cylinder which protrudes from a star base, a supporting column, which is mounted in the supporting cylinder such that it can be displaced in a vertical cylinder axis, for a base plate with a seat which is fixed on the base plate, a base arm which is fitted to the supporting column or to the base plate, and a pivoting arm, which is mounted on the base arm such that it can be rotated out of the seat region about a vertical axis, having a chest rest and side arm rests, and a support which has a star rest and is hinge-connected to the base plate via a lever mechanism which has fulcrums such that pressing down on the seat causes the star rest to move in the direction of the chest rest.

The present invention relates to a multi-posture body support device adapted for working proximate to the floor. The device comprises: a frame extending at floor level, the frame having a front section, a rear section, and an extendible post in the rear section, the post being in a substantially perpendicular orientation relatively to the floor; an upper support adjustably mounted to the post; and a knee support mounted to the frame in front of the post and below the upper support, the knee support having a proximate end positioned proximate to the post and a distal end opposite to the proximate end; the knee support being substantially flat longitudinally between the proximate and distal ends for supporting longitudinally the legs of a worker facing one of the rear section and the front section relatively to the frame.

A bicycle seat supported generally by a tubular V-shaped configuration with an offset seat post to allow for padded leg cradle supports, padded handles and adjusting handle grip bars. The bottom of the ergonomically designed offset walker frame has an adjustable rubber tip for height adjustment. The seat is on a fixed top post. The position can be adjusted up and down in height, forward and back and front to back. Using the handle grips the user can straddle the bicycle seat and rest the injured limb on the leg cradle supports without having to strap the injured limb to the walker frame. The walker frame has been ergonomically designed for balance. The tubular construction is comprised of a number of offsetting bends and spacers, which offset the leg cradle to the proper distance for comfort and balance. The padded handles are forward of the seat with rotating handle grip bars on the ends of the padded handles which gives the user more comfort and better control when using the walker frame making it possible to maintain better balance. The hands and wrists keep the frame in a vertical position and maintain control over the stabilization foot for better balance. The offset bends in the frame move the stabilization foot out of the way of the good leg and foot making for a less cumbersome and more comfortable natural stance. The stabilization foot is under the injured limb giving the injured user better balance, which improves comfort and makes for a simple easy to use walking device.
