Sturdy rolling table with lockable wheels and adjustable height.
Tabletop is 30x24 inches.
Tabletop height adjusts easily from 31 1/8 to 43 inches. If you remove the wheels (with a crescent wrench), you can get the lowest height down to about 28 5/8 inches.
The wheels' height can be adjusted individually with a crescent wrench to balance the table for when it's sitting in one spot.
