The folding wheelchair, so called because it is collapsible, is a type of manual wheelchair.
Its main advantage is that it is easier to transport and store than other types of wheelchairs.
It is available in both heavy-duty and lightweight models but its folding and locking mechanisms and reinforcing elements make it generally heavier than another type of chair which is the rigid wheelchair.
The usual folding wheelchair has an x-frame that allows it to be collapsed sideways so that it can be conveniently stored in without taking up too much space when it is not in use.
In its collapsed state, it can be placed in the trunk of a car, instead of having to arrange for a larger vehicle or more complicated means to transport it.
In contrast with the rigid type, the frame of the folding type of wheelchair is flexible.
A folding wheelchair is more stable on uneven surfaces than a rigid one.
This is because all of its four wheels remain on the ground as the frame yields to accommodate the contours of the uneven surface.
However, it is less stable on a hard floor surface.
The movable and adjustable parts of the folding chair may make it easy to stow and easy to transport but at the same time, these parts make it more prone to breakdowns.
There would be need for more frequent repair and replacement of these parts.
Thus, the expense involved in maintaining it in good working condition is greater than that for a rigid-framed chair.
The folding wheelchair is harder to propel than that which has a rigid frame.
It is also harder to maneuver.
Much of the force exerted in pushing and controlling it is absorbed by its flexible frame and so greater strength and dexterity is needed in propelling and maneuvering it.
The chair's relatively heavier weight also contributes to this issue with propulsion and control.
There are certain activities that it is best not to engage in while using a wheelchair that can be folded.
These include athletic activities.
The convenience of being able to fold it means that certain concessions have to be made in terms of the chair's strength and stability.
The same features that make the folding chair desirable also render it less stable and less durable.
By and large, folding wheelchairs are not optimized for self-propulsion and are appropriate for individuals who have little or no upper body strength.
These include very young patients (those who are 0 to 4 years old) or those who are 60 to 90 years old.
Stronger, more active individuals who are able to propel their own wheelchairs will do better in a chair with a rigid frame.
Portability and ease of storage is the focus of the folding wheelchair.
It is more convenient for the invalid's care giver to port, stow, and transport it even if it is heavier than a rigid-framed chair.
When folded, it takes up less room and is suitable for smaller living quarters that have limited storage space as well as for smaller vehicles that have less capacity.
