Have you tried a scooter? scooters are great to put plants on when you need them to be mobile. I use a wheelchair too because of my muscular dystrophy, I have several aerogards on scooters. I do have one rotating stand though, it doesnt have any identification on it though so I wouldn't know where to look to buy one, maybe at walmart or at a plant store? Possibly ebay? really though, my scooters work just fine, and I can't walk into tight spaces, lift potted plants or any of that fancy stuff a lot of people tend to take for granted so I'd say a scooter's wheelchair friendly, cheep enough too since theyre mostly sold as children's toys.
