Purchased used TrekDesk. Reasonably priced. It did not come with necessary screws for assembly. Contacted manufacturer who was extremely helpful. Quickly shipped the parts I needed. Assembly was very easy. Was able to do it by myself in about 1/2 hour. Make sure you have plenty of room though, because this desk is huge! I try to work out 4 to 5 times a week. The problem, however, is that if we work out 1 hour a day 7 days a week and then sit for 8-10 hours a day five days a week, it nearly defeats the purpose. Sitting is bad for us. Trek Desk allows me to stay moving and be productive. The accessories are also great. I especially like the file tray. I would definitely recommend this product to anyone looking to enjoy the ability to get in some exercise while getting work done.
