Dispite the negative reviews I've been in a wheelchair since 2002 always had a Permobil thought it was the best until this year when it was time for a new chair my rep from National Seating recommended I try the new Edge 3.0 was not to sure they let me try a demo I was sold this is by far the best riding most comforyable chair I've been in the cushion is so comfortable I LOVE my Quantum and National Seating in Evansville,Indiana and my ATP Shelby Bass
