About The Smirthwaite Hardrock Chair Accessories
Stabilizers stop sideways rocking and need the chair to be on a mobile base. The molded pelvic support gives snug, contoured support, and the pommel encourages hip abduction. For the tray there is a full-width handrail that helps stabilize the arms, front, rear and side retaining straps that hold the tray in position, and padded inserts fitted under or on top for comfort and protection.
Sizes vary by item, so call us if you want help matching parts to your chair.

My Service Technician is truly the best! He responded within a day and he fixed the chairlift in less than an hour! It’s reassuring to know that we can depend upon Custom Mobility!
