The elderly can be grouped depending on their mobility level. Each group has its own requirements to make their wheelchair seating experience safe and comfortable. Make sure to read every blog to thoroughly understand each category.
People who “can’t walk fast or far”, often encounter poor sitting posture because they are using the wrong wheelchair configuration. Therefore it is important to learn the correct seat depth, width, and height.
What is the correct wheelchair seat depth?
If the seat depth is too deep, then there is not enough space behind the user’s knees so it will be uncomfortable for the user to sit for long periods of time. The user will try to slide forwards to find a more comfortable position, compromising their spine positioning and dropping their head.
When the seat depth is too shallow, the lack of thigh and seat contact means the user leans forwards, drops their head, and put all of their weight on their feet to find some stability.

To measure the correct seat depth, the user’s hips should be as far back on the wheelchair as possible. Secondly, the position of the foot plates should be positioned correctly. Lastly, leave a space of two fingers (3 cm) between the edge of the cushion and the user’s calf.
What is the correct wheelchair seat width?
Sometimes user’s families may think that a wider seat width will be more comfortable for the wheelchair user however this is not true. If the seat width of a wheelchair is too wide, there is no proper trunk support for the user and they will lean to one side to find the support they originally lacked. This will cause problems in the long run such as scoliosis. If a better fitting wheelchair is unavailable, then the user can add lateral support or wedges on each side of the user’s thighs to make them more comfortable.
What is the correct wheelchair backrest height?
If the back height of a wheelchair is too low, the user will have no head support and have no choice but to slide forwards and drop their head. However, if the backrest is too high, self-propelling a wheelchair will be uncomfortable. Therefore, the correct back height for a self propel wheelchair therefore should reach the shoulder blades. For elderly users who have poor trunk control, the back height should be higher to provide more support.

If the elderly user needs to use the wheelchair for long periods of time, using a simple curved headrest will make resting in the wheelchair more comfortable. The curved headrest is height, depth, and angle adjustable. This headrest is able to be folded alongside the wheelchair.
We’re here to help
For this group of elderly users, choosing a wheelchair with the correct depth, width, and seat height will prevent the elderly user’s head from dropping. If necessary, the user can also add accessories such as a headrest to make the user more comfortable.
