Spencer has for years, concentrated its research and subsequent production on trying to resolve every possible problem that can make the transition from one floor to another impossible, difficult or uncomfortable. The result is a chair that descends the stairs safely and also reduces the effort on behalf of the operators. It can also be used for the transport on flat surfaces due to the presence of four wheels, two of which swivel, and a braking system which enables total stability during loading. The Skid-E chair is supplied with two polypropylene 50 mm [1.96 in] straps Weight: 12.5 kg [27.55 lbs] Skid-E - ZS30001E
