Correll’s Rectangle Blow-Molded Activity Table is waterproof and resists food, crayon, permanent marker and glue stains – along with just about anything else your kids can throw at it. This durable activity table comes in two height ranges and a selection of playful colors, so it’s perfect for your growing elementary students. The surface is textured but smooth enough for writing, and the top color goes all the way through. Legs attach to the welded steel frame with three bolts each, so it’s sure to stay strong and sturdy. Tables adjust in one-inch increments; standard tables adjust from 21 to 30 inches; short models adjust from 16 to 25 inches.
