Rucs is not a word in English. Did you mean 'rugs'?
Rugs are things you put on the floor to make it soft and warm.
Examples:
I have a nice rug in my room.
The cat likes to sleep on the rug.
We bought a new rug for the living room.
The rug is soft and cozy.
The rug is big and fluffy.
I like to sit on the rug and read a book.
