They don't. Their legs are in proportion to their bodies - they don't need to be any bigger.
To fix chairs with loose legs, you can try tightening the screws or bolts connecting the legs to the chair. If that doesn't work, you may need to replace the screws or use wood glue to secure the legs in place. If the legs are severely damaged, you may need to replace them entirely.
The kangaroos back legs are stronger then the front legs because they need the strength of thier back legs to jump and to use them to fight.
