If you can afford a variety of cat scratching furniture, you can place cat climbing frames on the carpet and attach scratching boards to make these areas a resting area for cats.

These cat scratching furniture can become the exclusive chair for cats, especially when there is only one person in your home and the cat is very dependent on you. Placing a scratching board or cat climbing frame near their favorite sofa or chair is more tempting for cats.
A plank with bark can be an ideal scratching board. However, such scratching boards also have disadvantages, as other small animals may live in them. So, if you can't make sure the board is clean as cat scratching furniture, you should probably place it somewhere else, such as near the cat litter. In fact, this is also a temptation for cats.
Find the furniture the cat has scratched, and find out where the cat hangs out. If the cat spends the most time on your chair, place a cat scratching furniture, such as a scratching board, near the chair.
You can also put clean clothes or personal items on the surface of those places (like your favorite chair), and don't put cat scratching furniture so that the cat will think these places are your "territory".
Through the above introduction and analysis of Choise of cat scratching furniture, hope it helps you.
