Demonstration Showroom

Finally, a place where you can experience not only what it’s like to work at a standing desk or a treadmill desk, but where you can actually compare different models. Check out all the equipment, from adjustable-height desks and walking treadmill bases to standing desk converters, monitor stands, keyboard trays, ergonomic keyboards and other vital accessories. Showroom visitors are more than welcome to bring their laptop computers, or use our computers to test drive a treadmill desk.
