Ganglbauer (1892) divides the whole order into two sub-orders only, the Caraboidea (the Adephaga of Sharp and the older writers) and the Cantharidoidea (including all other beetles), since the larvae of Caraboidea have five-segmented, two-clawed legs, while those of all other beetles have legs with four segments and a single claw.
They may have legs with wheels so that the chairs swivel and roll.
A platform bed typically sits on a wooden frame and may have legs or a smaller box frame attached to the underside.
These have legs that fold so that they take up less room when traveling.
Some companies make rebounder home-models, which have legs that can be folded for storage.
