It may be a good idea to purchase more than one wheelchair. Having a backup is always a good idea because sooner or later your main power or manual wheelchair may need maintenance. Also, if you are very active you may want to purchase a chair designed for a specific sport or activity.
Individuals that are full time power wheelchair users may need to have multiple chairs for indoor and outdoor use. It is also a good idea to have another wheelchair charged up and ready to go just in case an electrical failure occurs in your main power chair. This will eventually occur.
Transport wheelchairs can also be used as a convenient and inexpensive option for your short term transportation needs.
