Why are cushions important?

There are two main purposes of wheelchair cushions: 1) to help improve function and achieve a balanced posture, and 2) to redistribute the pressure applied by the sit bones when seated. Taken together, the cushion can impact the amount of support provided, which in turn determines how long someone can sit for, how easily transfers can be done, and posture of the hips. There are many types of cushions available on the market, as no one cushion is suitable for all individuals with SCI. To determine which is best suited for your needs, various factors are considered, including:

• The amount of pressure reduction/redistribution required
• Temperature effects (warm temperatures may lead to sweating, which may make the skin more vulnerable to injury and infections)
• Your level of injury
• Your ability to relieve pressure off your sit bones
• Your transfer techniques
• Your lifestyle

Although new cushions may be able to provide support and redistribute pressure applied by the sit bones, the effectiveness of a cushion decreases over time. Some research studies have looked into factors that impact deterioration of a cushion. Weak evidence suggests that how a cushion is used is a bigger indicator of deterioration compared to age of the cushion. For example, factors such as how you transfer in and out of your wheelchair, frequency of curb jumps or high vibration activities, exposure to the elements (rain, snow, etc.), moisture, and exposure to extreme temperatures can negatively impact the quality of your cushion.
