I bought this desk recently, and Uno furniture shipped it to my remote location in the South Island. I then followed the instructions easily to assemble the desk, and I have found it really good. It has up to 4 set heights, but I only use 2: standing up, and sitting down. All I do to go from one to the other is hit the button and it glides smoothly up to the set position I want. I have found it wonderful. with both an injured back and injured foot, I need to go from sitting to standing several times a day, and it does this with ease. Great desk thanks.
