VIVO’s desk riser

Space Efficient 31.5" Surface - The top surface measures 31.5” x 15.7”, which maximizes space while still providing room for dual monitors. The 31.3" x 11.8" (10.5" in center) keyboard tray raises in sync with the top surface. I mis-judged the height, which is why I need to sell it. I haven't used it and its available in the original box. I am too short for this riser which I intended to use for standing sometimes when working.
