The Elbow Support and Armrest Side Support are adjustable supports that help prevent your arms from sliding off the side and back of the armrest, particularly during tilt and recline and while repositioning. By preventing the arms from sliding off the armrest, the Elbow Support and Armrest Side Support allow those with reduced arm function to reposition themselves independently, drive on bumpy terrain and maintain control of their wheelchair. These arm supports work well with all of our other armrest options. Adjustable hardware allows the supports to easily adapt to your positioning needs.
