It's important for the wheelchair to be fitted properly and be as narrow as possible while maintaining comfort and safety. This will insure the best performance for navigating tight areas both inside the home as well out in public spaces.

A wheelchair that is too narrow or too wide can cause discomfort. When too narrow, a wheelchair can become restrictive and increase the likelihood of pressure sores, while when it's too wide, becomes more difficult to push due to the angle of the arms from the shoulders to the wheels.

To determine the necessary seat width, measure the rider's widest area of the body and add one inch. This will allow for optimum seat width while maintaining ideal usability, comfort and safety.

To determine the appropriate seat height, measure from the bend of the knee to the bottom of the foot. Subtract the height of the seat cushion if one is being used. If the wheelchair is not being self propelled by the feet, also add about 2 inches to allow for foot clearance.

The rear of the seat is generally set at lower height than the front of the seat to prevent sliding forward.

80° is the industry standard and most popular configuration. Keep in mind, for every 5° you add/subtract you are adding/subtracting 3/4" to the wheelchair's overall frame length. The longer the frame length, the more stability and the shorter the frame length, the less stable your wheelchair will feel.

Armrests are mostly a matter of personal choice, but most often users without much mobility appreciate armrests to help alleviate shoulder and back stress. Armrests also provide additional stability for users with limited upper body balance and are helpful when navigating in and out of the wheelchair. Additionally, armrests allow users the ability to do pushups, helping relieve pressure as well as protecting clothing from the wheels.

When armrests are not fitted properly the wheelchair can become more difficult to push. Not all armrests are adjustable. Height should be fitted to allow the forearm to rest fully on the armrest without pushing up on the shoulders. For users who sit at a table or desk, swing-away armrest can beneficial.

There are four basic types of armrests:
1. Full length, fixed height (entire armrest is padded with a non-adjustable height)

2. Full length, adjustable height (entire armrest is padded with various height seetings)

3. Desk length, fixed height (partial armrest is padded for easier access with tables, non-adjustable height)

4. Desk length, adjustable height (partial armrest is padded for easier access with tables, various height seetings)

Armrest that can be easily removed or flip up and down gives users the choice of when to use the armrests.

1. Swingaway, Removable Foot Rests swing aside to allow easy access in and out of the chair as well as unobstructed use with tables and desks. Removable footrests also help to make the wheelchair more manageable when traveling.

2. Elevating Leg Rests are used when better circulation is needed or there is limited mobility in the leg. They raise the foot, straightening the leg. A calf pad is usually included.

3. Fixed Riggings are attached to the wheelchair frame and are not collapsible or removable, but the height of the footplate can be adjusted to the proper fitting.

For optimum comfort and safety, leg rests should provide a proper foundation for the legs and feet. The bottom thigh area should be fully supported by the seat while the soles of the feet are supported by the foot rests.

Discomfort, stress and poor posture can be caused when the legs and feet are left hanging without the support they need or when the foot rests are too high. Poorly fitted leg rests can have a destablizing effect on the chair, making it more difficult to push and navigate due to improper weight distribution.

Removable and fixed footrests are available at different angles depending on the users needs. A lesser angle allows the feet to extend further in front of the wheelchair for people who do not bend well at the knees. It also allows the heels of the feet to avoid the wheels when using larger diameter casters. A higher angle will bring the feet closer to your body and the wheelchair, shortening the overall wheelbase, allowing the wheelchair to turn in tighter spaces.

The greater the camber angle, the further the distance between the bottom of the rear wheels and the closer the distance between the top of the wheels. Increasing the camber angle provides the rider with increased maneuverability and stability, but also increases the overall width of the wheelchair.

Typically 0-3 degrees of camber is considered standard for everyday use to accommodate narrow doorways and aisles. A higher camber angle is useful for sporting activities such as basketball where added stability and maneuverability is desired.

There are various types of wheel locks available:

1. Push-to-lock wheel locks are the most common. The break is engaged by the rider pushing forward and applying pressure with the palm of their hand until the lever snaps into position.

2. Pull-to-lock wheel locks work in the same manner as the push-to-pock except the lever is pulled forward. For some riders, it may be easier because it does not require as much upper body mobility needed to push the lever away from the body.

3. Swing-away, low-mount and under-mount wheel locks work in different ways depending on the style. These wheel locks help you avoid hitting your thumbs when pushing directly on the tires by mounting the wheel locks away from this range of motion. Due to its location, some riders with limited mobility may not be able to engage these wheel locks.

Wheel lock extensions provide a greater lever arm to apply and remove the locking mechanism, making the wheel locks easier to engage for a rider with decreased upper strength.
