All Terrain Powerchair Recommendations wanted

Can anyone comment on pros and cons for All Terrain powerchairs for someone with Duchenne? Looking for best comfort possible.

Hi Angela, Is this as their primary wheelchair? The cons for me when looking at these is their bulkiness and ability to get under ordinary tables etc and how much room they need to be transported. I'm a suburban wheelchair user who doesn't go off paved surfaces all that often and who has to transport my chair regularly. If those were not considerations though a all terrain would be very attractive to me. As you can swap out backrests and cushions with most of them comfort really comes down to trying a variety of set ups like any other chair. Sarah
