Page 12: The Seat Cushion
3.8. The seat cushion There is a choice of various different seat cushions, governed by your individual needs. The velcro fasteners fitted to the surface of your seat should allow you to attach the majority of seat cushions securely. The velcro fasteners prevent the cushion from slipping out of place even when you are standing up. -
Page 13: Gradients
4.2. Gradients When turning on a gradient, bear in mind you will have to sit square on to the slope before finally swiveling around to face straight downhill. In this side-on position there is a risk of slipping sideways down the slope. Either you or your accompanying person should take this risk into account and steer accordingly to compensate. -

To descend down over an obstacle (e.g. driving down from the kerb into the street), first tilt the wheelchair up onto the rear wheels, then push on and let the wheelchair down over the edge of the obstacle on two wheels (see diagram, above right). Should you have to be carried over three steps or more, request the assistance of at least two able- bodied persons. -
Page 15: Picking Up Objects From The Wheelchair
