Quick answer: Before buying anything for a DIY couch protector table, watch where and how your cat scratches for a week, measure the sofa arm height and depth, check how much hallway clearance you have, ask carpet shops for free remnants, list the tools you already own, and price plywood. Then compare that total, plus a weekend, against buying.
The most expensive DIY project is the one the cat ignores. Plywood, glue, carpet and a weekend of work add up, and a table that is the wrong height, wrong place or wrong texture will sit unused while the sofa keeps getting shredded. A little planning before you buy anything prevents almost all of that.
This guide is the 'measure twice, cut once' step for a carpet-remnant couch protector table in a hallway or entry. It pairs with our build guides but stops before the build: what to observe, measure, source and budget. The advice reflects what Humane World for Animals and Cornell's Feline Health Center say cats need from a scratcher.
Check 1: Watch your cat for a week
Do not guess. Spend a week noticing exactly where the cat scratches, which surface it uses and how it stands. Write it down, or take a photo of each spot.
| Question | Why it matters |
|---|---|
| Which arm? | Decides placement and whether you need two tables |
| Front, side or top of the arm? | Decides which face gets carpet |
| Standing tall or reaching sideways? | Decides height and face size |
| When? | Helps with training timing |
| Other spots too? | May need a second scratcher |
If the cat also scratches rugs or the base of the sofa, it may prefer horizontal surfaces. Read vertical vs horizontal scratchers before you design a tall table.
Check 2: Measure the sofa arm
Measure the arm height from floor to top, the arm depth from front to back, and the arm width. Note whether the arm is square, rounded or sloping. These numbers decide your table size. The table should be level with the arm or slightly below, and its scratch face should be as tall as possible. Our sofa measuring guide and height matching guide explain each measurement.
Check 3: Measure the hallway
Hallway sofas need extra checks. Measure the walkway width with the sofa in place, check the swing of nearby doors, and look for radiators, sockets and skirting that may get in the way. Aim to leave at least 80–90 cm of clear walkway after adding the table.
- Walkway width after the table: at least 80 cm.
- Door swing: the door must not hit the table.
- Radiators: keep cardboard and carpet away from heat.
- Sockets: do not block outlets you need.
- Floor type: tiles and wood need a non-slip base.
Check 4: Source carpet remnants for free
Carpet shops and fitters often have offcuts they will give away or sell cheaply. Ask for short cut-pile carpet in a size of at least 50 × 70 cm. Avoid looped carpet (it snags claws), carpet with crumbling foam backing, and anything with a strong chemical smell. You may also find leftover carpet from your own home or neighbours.
Remember that you can use the woven back of a remnant as the scratch face. It is rough and durable, and less likely to teach the cat that floor carpet is for scratching.
Check 5: List the tools you already have
| Tool | Needed? | Alternative |
|---|---|---|
| Saw (circular or jigsaw) | Yes | Ask the timber yard to cut panels |
| Drill/driver | Yes | Borrow from a neighbour or tool library |
| Utility knife | Yes | - |
| Clamps | Helpful | Heavy books while glue sets |
| Sander | Helpful | Sandpaper and a block |
Many timber yards and DIY stores cut plywood to size for a small fee or free. If you lack a saw, give them a cut list and you only need to drill and glue at home.
Check 6: Price the real cost
Add up plywood, glue, screws, tacks, finish and any weights for the base. Include tools you need to buy or rent. Then add the value of your time: most first builds take a weekend once you count trips to the shop and drying time.
| Item | Typical share of cost |
|---|---|
| 18 mm plywood | Largest |
| Carpet remnant | Often free |
| Glue, screws, tacks | Small |
| Finish | Small |
| Base weight | Small |
| Tools (if buying) | Can exceed materials |

Price it against a ready-made table Before you buy plywood, compare your total with the CozeCat Side Table. It ships with Next-day shipping on in-stock units and 30-day returns (return shipping is the buyer's cost).
Check 7: Decide whether DIY is right for you
DIY suits people who enjoy building, have tools or can borrow them, need an unusual size, or have free materials. Buying suits people short on time, without tools, who want a finished look or a replaceable surface. Neither is wrong.
- DIY if: you like making things, the sofa arm is an unusual size, and you have a free weekend.
- Buy if: you want it this week, have no tools, or want a sisal face you can swap rather than re-glue.
Questions to ask about any ready-made table
If you decide to buy, check a few things first. Is it stable enough for a cat to lean into? Does its height match your sofa arm? Is the scratch surface replaceable? What are the shipping times and return terms? Our trust checklist for buying cat furniture online and sofa scratcher buying guide go through each question.
Height, stability and a replaceable face The CozeCat Side Table was built around those three checks, with a sisal face that slides out for replacement.
Your one-page plan
- Notes on where, how and when the cat scratches.
- Sofa arm height, depth and shape.
- Hallway clearance and door swing.
- Carpet remnant sourced, aired and checked.
- Tool list and cutting plan.
- Total cost and time estimate.
- Decision: DIY or buy.
With this plan in hand, the build itself is straightforward, and the table is much more likely to be used. When you are ready, follow our step-by-step build guide and our list of common mistakes.

Protecting the sofa while you plan
Planning takes a week or two. In the meantime, protect the sofa arm with a throw or a temporary cover, and put any scratcher you already have right next to it. A cardboard scratch pad leaned against the arm can buy time. Our guides to what to put on your couch to stop scratching and cat deterrents for couches list short-term options.
Common planning mistakes to avoid
Buying the carpet first
It is tempting to grab a nice remnant and design around it. Measure first. A remnant that is 10 cm too short for the scratch face is wasted, and you may have to piece two together, which leaves a seam the cat will pick at.
Measuring only one arm
Sofa arms are not always identical, especially on older or sectional sofas. Measure both, and note which one the cat uses most. If it uses both, plan for two tables from the start so you buy materials once.
Forgetting the floor
Tiles and wooden floors in hallways are slippery. Plan a rubber or felt base pad, or a small rug, so the table does not slide when the cat pushes against it.
Underestimating drying time
Glue and finish need time to cure, and new carpet needs airing. Build this into your plan so you are not tempted to put a smelly table next to the sofa too soon.
A sample shopping list
Once your checks are done, a typical shopping list for one hallway table looks like this. Adjust quantities to your measurements.
- 18 mm plywood cut to your cut list (top, sides, back, base).
- One carpet remnant, at least 50 × 70 cm, aired for 48 hours.
- Non-toxic PVA wood glue and a water-based carpet adhesive.
- Wood screws, 40 mm, and a handful of carpet tacks for hidden edges.
- Water-based clear finish for the top only.
- A rubber mat or felt pads for the base, plus a paving slab for weight.
If your list includes a saw and drill you do not own, price them now. That single line often decides whether DIY still makes sense.
Before you buy: couch protector table FAQ
What should I measure before building a scratcher table?
Sofa arm height, depth and shape, plus hallway width and door swing if the sofa is in a hallway.
Where can I get free carpet remnants?
Carpet shops, fitters and neighbours often have offcuts. Ask for short cut-pile pieces without crumbling backing.
Is it cheaper to build or buy?
If you already have tools and free carpet, DIY can be cheaper. If you need to buy tools, buying a table is often similar in cost and saves time.
How long should I watch my cat before building?
About a week, so you see the full pattern of where and when it scratches.
