Dynamic seating components are often used with wheelchair users who generate strong, repeated, or sustained forces and may already have a history of damaging equipment. These components must absorb those forces while moving and returning to their starting position. For this reason, dynamic seating hardware needs to be designed to withstand significant repeated stress.

Three primary factors affect dynamic seating durability: the amount of travel available, the level of resistance provided, and the overall design of the component. These factors work together to ensure forces are absorbed effectively without being transferred unnecessarily to the wheelchair frame.

If a dynamic seating component reaches its full available travel, client-generated forces may begin to transfer through the dynamic hardware and into the wheelchair frame. This can increase stress on the seating system and may contribute to equipment damage. Proper resistance helps keep the component functioning within its intended movement range.

Resistance must be appropriate for the individual wheelchair user. If resistance is too low, the client may push the component through its full travel and transfer force to the wheelchair frame. If resistance is too high, the component may not move enough to absorb forces effectively. The goal is to achieve enough movement to absorb forces while avoiding the end range of travel.

Durable materials and a simplified design can help reduce wear and potential points of failure. Components with fewer individual parts, screws, bolts, and connection points may experience less movement between parts and therefore less wear over time. A robust, streamlined design is especially important for clients who generate significant forces.
