This desk has CHANGED MY LIFE!!! I received it as a gift for my birthday and now cannot ever imagine going back to working exclusively at a seated desk. Three weeks ago I was sedentary every day. The day that I assembled the desk I walked almost 5 miles. I walk, on average, between 3 and 5 miles daily right now. My treadmill was set up downstairs behind the sofa, but close to the children's desks/homework area. I am now downstairs with them, walking, working, running my business while they are doing their homework, watching a movie, or playing Wii. My low back pain is GONE!!! I feel so great about the fact that each and every day that I am working on my business I am active and walking. Thank you so much for this fabulous product. It truly has changed my life.
