If something is suited to something else, it means it is right or good for that thing.
The word 'suited' makes people think of things that go well together or fit perfectly.
Examples:
The warm coat is suited for cold weather.
This job is suited to me.
The big shoes are not suited for the little feet.
The cat is suited to the house, but the dog is not.
The superhero is suited to fight the bad guys.
The big bed is suited for the giant.
