My dad has been using a wheelchair for the past 2 years after he met with a car accident. He has been using a normal wheelchair. Last day he asked me if I could buy a motorized wheelchair for him, so that he could travel with more ease. So I have checked a few motorized wheelchairs online. I like Trident 20 inch front wheel powered wheelchair from online shop Agecomfort the most. Any Suggestions will be good about the particular model or any other,
If you know his measurements and weight, you can pick these chairs up second hand for about $200 locally.
With a prescription from an MD, you can rent a new one, and your insurance might even cover 80% of the rental.
