Some pieces just seem to get marked for special scratching treatment because they feel just right to your cat. In this case, there are several options you can try:  Apply double-sided tape to the furniture.  Cats dislike the sticky feeling and won't continue to stick their claws wherever it's sticky, as the hairless skin of the cat's paws is extremely sensitive to touch.  For larger furniture, adhere masking tape over the arms, or on the back of the furniture where the cat will often enjoy playing (and hiding from water spritzing). For a larger area, such as a rug or carpet, leave contact sheets sticky side up over the surface you want to protect.  You can also buy a product called "Sticky Paws," which are medical grade adhesive sticky strips that can go on curtains, drapes, carpets, and anything else that might be a bit too tempting for your cat.  Use the “knobby” side of a plastic or vinyl floor runner along the back of the couch to deter scratching. The cat won’t like the feel of the pointy knobs on their feet.

You could also try placing blown-up balloons hidden underneath a sheet covering the furniture which will burst when clawed, causing the cat a fright that will be associated with that piece of furniture long after the balloon has popped.

Cats will not be interested in those types of fabrics as they won't be able to get their claws through. Cats will scratch any furniture made with a thin loose-weaved fabric. Also consider using a “Scat mat” to deter cats from certain surfaces and areas.
