Stand-up Wheelchair

I am a wheelchair user who was recently diagnosed with a pressure sore and I am looking to get back to regular activity and prevent this from happening again! This standing wheelchair would be a huge asset to recovery as well as long-term better health! There is a backorder date for new orders but I'm looking to purchase this asap. The full power chairs are more expensive, but this one is manual, and should work fine. Any extra funds would be used for medical bills.  Thanks for your support!
