I've been using the Invisible Rack™ for close to 7 years. I built the proto type unit in my garage out of the frustration that came with trying tripping over other types of Music Stands. I built the Invisible Rack™ proto type without thinking anyone else would want one, it was just something that worked for me.
After years of having countless musicians and others comment on it and wondering where they could get one, I finally broke down and started producing them in limited quantities (at least for now).
There really is nothing else quite like it. I'd be lost without mine!
