Part lectern, part sit-stand cart: the column lifts the 20 by 16 inch top from 28.5 inches for seated work to 44 inches for standing presentations. The tabletop tilts through 0 to 180 degrees and locks with a knob, with a non-slip lip that stops laptops and papers from sliding off. Below the top, a 12 by 14 inch middle shelf, a 7 by 8.5 by 8 inch compartment and a 7 by 12 by 11 inch bottom compartment store books, a projector remote or a tablet. Four universal casters carry it between classroom, conference room and church hall. The 20 by 16 by 2.5 inch base and metal frame support a total of 200 lbs, and the rustic brown engineered wood panels resist scratches. Net weight is 25 lbs. Assembly required.
