I hate sitting all day. I built this little stand to allow my work laptop to be used in a standing position. Its not quite done as I still need to finish the keyboard tray (the keyboard sits on some books). I have no idea what material it really is as its all drops. I think its 1.5" square tubing, some 2" by 1.5" tubing, and some 3" by 1/8" flat bar.
