A cat that scratches a sofa arm may need a tall vertical cat scratching post; a cat that works at a rug or low sofa edge may prefer a horizontal cat scratcher. The best comparison starts with your cat’s posture and the location of the target.
Quick take: Offer two stable options near the problem area, watch what the cat chooses, and keep the preferred option accessible.
Observe the angle your cat already uses

Watch without interrupting: does your cat reach upward against a sofa side, or stretch forward and scratch at a lower surface? Note whether the cat uses claws to rake a vertical area or works along a flat mat. The ASPCA says some cats prefer horizontal, vertical, or slanted surfaces, and individual preferences differ.
Use this observation to select the first option. A tall post near a sofa arm may suit an upward stretch; a horizontal cardboard cat scratcher (paid link to Amazon) or sisal mat may be a better trial for a cat that scratches low surfaces.
Offer both orientations without forcing a choice

Place a vertical cat scratching post and a horizontal scratcher near the sofa target. Keep both stable: a post should not rock, and a mat should not slide or curl. Try different surfaces such as sisal and corrugated cardboard if the first material gets little interest.
Do not pick up the cat and press its paws onto a scratcher. Let the cat investigate and use it voluntarily. If one option is ignored, change its position or texture before deciding that your cat does not like scratching surfaces.
These generic product phrases—vertical cat scratching post, horizontal cat scratcher, and sisal scratching mat—can help you compare category choices later; they are not endorsements of a particular listing.
Use placement to prevent repeat sofa scratches

Start with the scratcher beside the exact arm, corner, or low panel the cat targets. Once the cat is using it, you can test moving it a small distance while keeping it easy to find. The ASPCA advises placing suitable alternatives near objects a cat is inclined to scratch and providing a variety of attractive options.
Protect the sofa with a furniture-compatible cover during the transition, and keep a clear path to the scratcher. For help deciding where to set up a post, read where to place a scratching post beside a sofa and the cat furniture protection guide.

How to decide in your home
Let observed behavior guide the first choice: If the cat stretches upward on a sofa arm, put a stable vertical scratcher near that spot. If the cat scratches the floor or rugs, offer a horizontal surface in the travel path. Some cats use both, so providing both orientations can be more practical than forcing a single answer. Choose a surface long or tall enough for a comfortable stretch and stable enough not to tip or slide.
Evaluate over several days: Keep the current safe scratching option available while introducing the new one. Notice whether the cat approaches, scratches, avoids, or walks around it; move or change the surface if needed. Do not hold the cat's paws against it. Inspect cardboard, sisal, and fabric for loose pieces, and replace a damaged surface. If scratching suddenly changes along with other behavior or health signs, ask a veterinarian. The goal is a usable alternative near the problem location, not merely a product that looks right in the room.

Horizontal cardboard scratcher to compare
If your cat already uses a horizontal cardboard surface and you have room for the listed size, compare the PetFusion Jumbo Cat Scratcher Lounge on Amazon (paid link). Check the dimensions and care instructions, keep it on a level surface near the current scratch target, and inspect it for loose or damaged material. Leave a familiar safe option available while your cat tries a new scratcher.
