Ideal for any physical therapy facility. Adjustable staircases are designed to help users gain strength and confidence for going up and down stairs after an injury or surgery. Constructed with a sturdy, hardwood plywood base, steel fasteners (no glued wood dowels), and 1.5" diameter stainless steel handrails with end bumpers for extra support and durability. A second knob removes any side-to-side play for a rigid upright. Height adjustments are quick and easy thanks to self-indexing spring action plungers and numbered height indicator strips—no holes to line up or count! Additionally, each step includes two, full-width treads for increased safety and to help reduce the risk of slips and falls.
