Use Sammons Preston Wheelchair Side Supports to position individuals in wheelchairs and create a more comfortable, safe, sitting experience. Made of closed-cell foam, the supports can be modified with an electric knife for customized fit. They are designed to fit either the left or right side of most standard wheelchairs, and can be used on both sides or individually. Optional torso support of open-cell foam fastens to side support with hook-and-loop material.
