The ZÜCA frame is as rugged as it is stylish.  Constructed of aircraft aluminum, it can support up to 300 pounds, which means that you don't have to waste time looking for a place to sit!  Not only that, but it has two sets of wheels to help you get up those annoying obstacles like curbs and stairs. Just choose a stylish insert (more than 30 to choose from), add one of our optional accessories (like seat cushions), and you're ready to roll!
