Just what I was looking for. The adjustable part is sturdy and works well. The instructions for putting it together are good and I leisurely took a couple of hours. The actual working space for the desktop is 23 1/4" x 47 1/4". For sitting, it is a bit high (30"), even with my chair at highest setting. So I am getting an under-desk keyboard and mouse tray to keep my arms at a good angle. However, there is a cross-bar under the desktop, which limits the options of a keyboard tray (if you already have one). The cross-bar is 11" from the front of the desktop.
