Unique in design and versatility, this modular raiser has been carefully developed using feedback received from Occupational Therapists. Designed to raise chairs, settees and beds equally well. Discreet when used under furniture, but has maximum support giving security and reassurance. Each support pivots on the link bars to ensure a snug fit to the side of the furniture either at the corner or as a central support along the side of the bed supported. The whole unit is height adjustable with simple to use clip on sections, each 20mm (3/4"), giving a wide range of heights. Height without adjusters is 80mm (31/4"). Supplied as individual sections to ensure you have the parts you need to customise the raiser for the job required. For example, to raise an armchair by 115mm (43/4"), you would require two raiser packs, one pack of spreader bars and one pack of height adjusters, leaving you with five spreader bars and four height adjusters for the next chair or bed.
