Gas springs have a number of advantages over coil springs.

1. They can offer a much higher force in a smaller package than coil springs.
2. On compression they do not bounce back, and the extension rate can be controlled, giving a smooth return.
3. Typically gas springs have a low compression rate, but if required this can be increased.
4. With a wider range of end fittings available, gas springs can be easier to fit.
5. A wide range of additional features can also be offered.
