The Techni Mobili Deluxe Rolling Laptop Stand is made of heavy-duty engineered wood panels with a moisture resistant PVC laminate veneer and a scratch-resistant powder-coated steel frame. The main table panel tilts so you can adjust it to the most ergonomic, comfortable working angle. It also features a safety edge-stopper to prevent objects from sliding off when the panel is tilted. You can also easily adjust the height between 30 and 35 Inch with a knob system. The extended 4th leg provides increased stability. Two of the fours non-marking nylon casters include locking mechanisms. The main tilting table panel has a 30 lb weight capacity and the stationary table panel has a 45 lb weight capacity.
