Correll Height Adjustable Activity Table is made of Thermal Fused Laminate (TFL), which is a resin-infused laminate, not glued on like high-pressure laminate. It is fused to the board using a heat treatment process. Height adjustable from 19" to 29" in 1" increments. Top resists scratches, dents, paint, markers, crayons, and food and juice stains far better than melamine. 1.25" thick high-density top is sealed on both sides preventing moisture from entering the table and causing warping. Heavy-duty legs include oversize hairpin brace and shouldered set screws for maximum safety. Shoulder on leg set screw provides an extra measure of security even if the legs are not properly tightened. Leg mounting brackets are pre-attached with seven screws plus three additional screws in the leg plate. Top Color: Gray Granite; Color Family: Gray; Base Color: Gray Granite; Top Shape: Rectangular.
