I work from home and before I had this desk I sat all day for 8-10 hours a day. I knew I needed to get my fat butt up while at work and these guys make a great desk. Having put many bookcases, desks etc together, this was one of the first pieces that had everything very well organized and mapped out. It was a breeze to put together. The desk is smooth and virtually silent when going up and down. I would recommend the preset button control option. It is easy to flip flop from standing to sitting in seconds.
I finally have enough space to have my Mac and PC running at the same time and on the same desk! Love this desk!
