There are not enough good things to say about this - I'm a graphic designer/business owner who sits in front of her computer for an ungodly amount of time, so needing to get up and move around from time to time - the goal is every hour for at least 5-10 minutes - will continue to help me get more endurance and help keep my arthritis at bay.  It took a while to put together, but ultimately is probably the best desk I've ever had, and it's ability to help me start to feel better, is amazing!  Thank you!
