Dunno if this is any help, Lottie, but my friend's cat Tigger doesn't much like vertical scratching surfaces (might be something to do with him being a very big cat) and at first he didn't even scratch the carpet! (he was four when my friend got him). We found tho, that he absolutely LOVES scratching on sample squares of carpet! Weird huh? He adopts them as his own (he has several around the house) and never even sits on the floor - only on his 'mats'!! He also 'fights' them when he gets the skits, so they're an all-round benefit! Cheap too!
