With this set of two elastic bands you can do a number of things, although they are primarily made for the AIRHAWK air cushions.
The AIRHAWK is an inflatable seat cushions to provide more comfort on hard seats or bumpy roads. An AIRHAWK air cushion will last quite a while, but the elastic straps tend to be lost, get stretched , eating by your dog, or someone uses them and doesn't bring them back. Anyway, they may be untraceable just when you need them, for whatever reason. Fact is, with this set your AIRHAWK air cushion can be fastened again for many pleasant miles.
One set is a pair, which means two elastic straps. That should be enough to fix any AIRHAWK cushion.
