We have a quantity of these sit/stand desks made by Steelcase. They are rectangular in shape and have a hand crank where you can adjust the seating or standing height. They are in excellent working condition, sturdy, and the top is made with a quality laminate. These have only the most minor usage marks, small nicks in the formica, and small chipping in the paint on the bases. We are having a blowout sale. We also sell a matching desk as a corner desk depicted in the last picture. PLEASE NOTE: If you purchase multiple units, we will supply half of the amount of cranks as we have more desks than cranks. Cranks not sold separately.
