I'm looking for a standing wheelchair, or possibly two, for two users. The first user is approx. 5'10", roughly 18 x 18 seat. I would prefer power for him. The second user is small ... seat no bigger than 17 x 17, but 15-16 wide by 16 deep would be better, and a relatively short distance from seat to footrests. Manual or power would work for him. Let me know what you have ... model, size, features, price, etc. Price is definitely a consideration. Thanks.
