These adjustable legs offer an excellent solution to early childhood classrooms that require low-height worksurfaces. They attach easily to Lorell Rectangular, Round and Kidney-shaped Activity Tabletops (sold separately) and adjust from 17" to 25" in 1" increments. Each leg has a Silver Mist upper portion that is fixed onto the tabletop and a chrome lower insert that slides into the upper portion for easy height-adjustment.
