I'm a C5/6 Quad and have the above decked out model as a back-up chair. I prefer a lightweight rigid. If anyone wants to trade or donate an older but CLEAN rigid chair, I would be most thankful. I am seeking to build strength to propel myself and transfer unaided. Keep me in mind when you are due a new chair. I gave my last powerchair to a 16 yr old boy with a new injury and I received more than I gave. mark
