These Leg-X Chair Raisers, supplied as a pack of 4, have been specifically designed to enable chairs with ordinary straight legs, such as dining chairs, dressing table chairs or traditional armchairs to be raised quickly and safely but at the same time very discreetly.Made from very strong but lightweight injection moulded plastic the Leg X Chair Raisers have internal fins which grip the chair leg securely. The chairs height is adjusted by adding or removing the little plastic inserts (included) until the perfect height for the chair is achieved, alowing the user to sit down or stand up with the least possible effort.
