This is a white metal computer stand with a clamp (grommet) mounting system. It is sturdy and offers excellent stability and durability. - Color: White - Type: Computer stand, arm - Material: Metal - Mounting type: Clamp, grommet I purchased this as a laptop arm for my home desk, but unfortunately, it didn't fit due to the size, so I am selling it. After setting it up on the desk a few times, the cushion on the part that attaches to the desk (as shown in photo 3) has come off. Photo 4 shows some marks. It should work fine if you have a desk that can be securely fastened, but please refrain from purchasing if you are concerned.
