Design and construction of a human powered vehicle seating simulator for diagnostic testing
A seating simulator was built to test the influence of various seating positions on human cycling power output. The simulator measures a rider's physical stress required to produce a certain power output. A heart rate monitor is used to find the rider's physical stress level. The theory is that the …

The impact of specialist seating on a person's quality of live and functional abilities
A good posture is required in seating to provide a stable and balanced position from which activities can be completed independently, ensuring that the body is at the least risk of damage. When sitting with a poor posture, an imbalance of weight distribution can lead to the development of pressure …
