This Ultimate Support Systems keyboard stand is in good working order and is a light weight aluminum tube design. It can be broken down for storage or transport. I have only used this in my home and I have modified it with a Fellows computer keyboard sliding drawer so that I could locate my computer keyboard and mouse under, and in front of my music keyboard when recording keys to my computer. The stand is fully functional without the sliding drawer should you not want to attach it, but it is included in this listing (a $30 value). The drawer attaches with four small machine screws and nuts (included) and may need some adjustment depending on your preferred keyboard angle and setup.
This stand can accommodate keyboards up to 41 7/8 inches wide. The depth of the two keyboard support arms is 13 1/2 inches from the back of each arm to the front support bumpers. Your keyboard depth can be more than 13.5 inches within reason. It has four feat and is missing one of the four plastic tube caps on the two aluminum tubes that the feet are attached to (see photos). I positioned the aluminum tube with that missing cap toward the wall when I was using this stand so it couldn't be seen from my sitting position. The keyboard height is adjustable up or down using an allen wrench (not included) and the keyboard angle is adjustable using the hand knobs.
This Ultimate Support Systems keyboard stand has some scratches and nicks but is in overall good condition, and is fully functional.
