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.
Casters typically come in sizes from 3"" to 8"". The smaller the caster the better the maneuverability of the chair and the less likely it is to shimmy. But smaller casters on unpaved surfaces, riding in and out of elevators, or passing over street grates can be more problematic. Smaller casters are typical of chairs used for sports like basketball, which is played on an even, hard surface, yet their maneuverability makes them popular for everyday use. 3"" casters require the most riding skill and may not be the best choice for a first time wheelchair user.
The large 8", pneumatic (air-filled) caster provides the softest ride and easily rolls over bumps and raised surface, yet makes propelling the chair more difficult. Because of their size, 8"" casters can be an obstruction coming into contact with furniture or the rider's foot. Pneumatic tires need to be kept inflated with the correct pressure, and are capable of going flat.
4" to 6" casters offer a good combination of maneuverability, performance and ease of riding over surface obstructions. Composite (airless) casters offer better durability and quicker ride, while pneumatic casters provide a softer, slower experience.
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.
A chair's rear seat-to-floor height is most commonly set at a height 1" lower than the front seat height.
The rear of the seat is generally set at lower height than the front of the seat to prevent sliding forward.
1. Pneumatic (air-filled) tires provide a softer ride, but need to be kept inflated. Because pneumatic tires are softer than urethane tires, they are harder to push, with more resistance to the shoulders.
2. Pneumatic Flat Free (foam-filled) tires provide a stiffer ride compared to air-filled tires, and will never go flat.
3. Urethane (solid, flat-free) tires provide the quickest and stiffest ride. And they will not go flat.
Tire Tread also affects the wheelchair ride. Tires with very little tread offer a quicker ride and turn more easily because there is less rubber in contact with the ground, causing less friction. "Knobby" tires with deep treads are helpful on unpaved and rougher surfaces, yet offer less maneuverability. A 1 3/8" treaded tire is a good basic tread for everyday use.
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.
Using wheel locks as a braking device can cause injury and excessive tire wear and should never be used in this manner.
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.
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.
The QRi comes standard with 0" or 1" of frame inset, a highly adjustable axle plate for perfecting your Center-of-Gravity setting, and multiple front frame angle options. The right fit gives you the ability to perform at your maximum level of function and efficiency.

Comfort and ease-of-use are two of the most important features in a "general use" backrest. The JAY GO Backrest fulfills both these needs and more. Comprised of super soft 1 1/4" thick foam and a tension-adjustable contour strap system, the JAY GO Backrest is one of the most comfortable, supportive surfaces available. Add in a stretchable water-resistant cover and you have an ideal combination.
Made with 1 1/4" of extra soft foam, the JAY GO Backrest is incredibly comfortable. The big advantage of a tension-adjustable strap system is the ability to customize the shape of the backrest. This provides clinicians the opportunity to create custom contour shapes that optimize user support and comfort. The Dartex® coated cover repels and beads fluids, which makes cleaning a breeze. This cover also protects the inner foam from odor- causing moisture The other big advantage to the JAY GO Back's tension adjustable-system is its ease-of- installation. Wrap-around Velcro sleeves conform to almost any back-tube diameter, and they are extremely easy to attach to the back posts
This Jay Ion Cushion features super soft foam on the top, structural foam imbedded on the bottom sides. Together they balance comfort with support. Add in a layer of reticulated foam in the cover, and the Ion takes on the additional benefit of being able to absorb both heat and moisture.
The Ion's thin fabric weave makes washing and drying the outer cover a snap. The inner water-resistant cover can be easily wiped off in seconds. When moisture strikes, cleanup is quick and easy.
To maximize immersion, reduce shear and help properly redistribute body weight, the Ion cover is designed with a stretchable low-shear cover material. This is important because reducing shear is a key factor in maintaining user tissue integrity
