A creeper is a low-profile tool used to help a person more easily slide in and out of confined spaces, such as the underside of a car, for performing inspection or maintenance.
They are built with a low profile to reduce the amount of added height above the ground, thereby providing as much clearance as possible for the person lying on it.
[2] Some also have ergonomic shapes or cutouts for the arms and shoulders providing extra room to make it easier to work in the confined space.
Other types of creepers include specially designed mats (creeper mats), and there are also various improvised solutions such as lying on cardboard.
Some creepers have dual-uses, such as being able to be folded to make a chair or a stool, or for compact storage.
