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.

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.

To determine a chair's back height, measure from the seat upholstery at the seat rail to the top of the back upholstery.

• Offset Axle Plate: This style combines the standard rectangle and curved shapes. Other than this stylistic difference, this option functions just like the standard axle plate.
• Amputee axle: This offsets the axle behind the backrest for enhanced rearward stability. This changed center of gravity corrects any imbalance resulting from the amputee’s lack of forward body weight. Note that with this option the overall length of the chair is extended.
• Curved Axle: Unlike the rectangle axle plate, the curved axle plate is curved. This allows the chair to be configured to more seat-to-floor heights. In most cases, the customer will just specify their required seat-to-floor height. The manufacture, while building your chair on the factory floor, will appropriately choose between the curved and standard axle plates in order to accommodate your preferred seat-to-floor height.

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.
