Gas springs do the lifting on a gas operated R82 High-low frame. The spring has to be matched to the combined weight of the seat and the child in it, otherwise raising the seat is either too heavy for a carer or the frame rises too quickly.
Three spring strengths are available, and this is the part to order when a client has grown, when a heavier seating system has been fitted, or when an existing spring has lost its assistance. Replacing it restores smooth, one person height adjustment from floor level up to table height.
