Quick answer: Start with a sturdy IKEA cube shelf, clad its sides and top in sanded, sealed HT-stamped pallet boards, turn two or three cubes into cushioned cat cubbies, add a sisal panel on one side and a perch on top, then anchor it to a wall stud. It looks like a bookcase and gives cats climbing, scratching and resting space.
Many pallet cat towers look exactly like what they are: stacked pallets. An IKEA hack solves that. A ready-made cube shelf provides a square, strong frame, and pallet wood adds warmth and texture on the outside. The result is closer to a rustic bookcase than a cat tree.
This guide builds on the IKEA hack DIY cat tree that looks like real furniture and uses salvaged wood for the finish. For other tower styles, see the DIY cat tree hub.
Choosing the base shelf
Cube shelving units, such as IKEA's KALLAX range, are popular for this hack because the cubes are close to the size of a cat bed and the frame is heavy. A two-by-four or four-by-four unit laid upright gives several levels; a horizontal two-by-four makes a long, low cat lounge.
Check the weight rating for shelves and the top before you start, and confirm the unit includes a wall restraint. Particleboard frames are strong in compression but weak at screw holes, so plan to fix cladding with glue and short screws into the thicker panels, not the edges.
Why this hack works better than stacking pallets
Stacked or upright pallet towers rely on the pallet's own joints, which were designed to carry boxes on a forklift, not to stay rigid when a cat leaps onto a top corner. They also have gaps between deck boards that can catch paws and tails. A cube shelf gives you square, flush surfaces and a frame designed to carry weight on every shelf.
Using pallet wood only as cladding also means you need far fewer good boards. You are covering the outside, not building structure, so split or short pieces can still be used, and the shelf does the structural work.
Finally, the hack is reversible. If you move or your cat loses interest, you can remove the cushions and sisal and keep a rustic bookcase.
Sourcing safe pallet wood
Only use pallets stamped HT, meaning heat-treated, under the IPPC international standards (ISPMs). Avoid MB stamps, unstamped pallets and boards with stains or smells. Look for boards with straight grain and few knots for cladding; save knotty pieces for hidden areas.
De-nail carefully, cut boards to length and sand all faces, then wipe them down with a damp cloth to remove dust. Let them dry fully before cladding.
Tools and materials
- One cube shelving unit with its wall restraint.
- Two to three HT-stamped pallets, depending on the unit size.
- Pry bar, hammer, hand or reciprocating saw for de-nailing and cutting.
- Random orbital sander and 80, 120 and 180 grit discs.
- Construction adhesive and short wood screws (shorter than the panel thickness).
- Drill-driver, countersink bit, measuring tape and pencil.
- Sisal mat or rope, staple gun and non-toxic glue.
- Water-based polyurethane or hard wax oil and a brush.
- Cushions or foam cut to cube size, plus fabric for covers or curtains.
Check screw length carefully. A screw that pokes through the inside of a panel creates a sharp point in a cubby where a cat sleeps.
Planning the layout
| Cube | Use | Treatment |
|---|---|---|
| Top surface | Perch and lookout | Pallet-board top with a cushion or sisal mat |
| Upper cubes | Cat cubbies | Cushion, optional curtain or fabric front |
| Middle cubes | Books, baskets | Leave as storage |
| Bottom side | Scratching | Sisal panel on the outside face |
Mix storage and cat space so it reads as furniture. A shelf with every cube full of cushions looks like a cat tree; one with books and baskets alongside looks like a bookcase.
Cutting and fitting the boards neatly
Measure each side of the shelf and cut boards about an eighth of an inch long, then sand the ends down to a snug fit. Dry-fit a full side before gluing, swapping boards around until the colours and widths look balanced. Start at the bottom and work up, so the last trimmed board sits at the top where a perch cushion will hide its edge.
Round the front edge of the top boards with sandpaper. That is where cats land and push off, and a sharp edge is uncomfortable for paws.
Cladding the shelf
Lay pallet boards horizontally across the sides and top, trimming the last board to fit. Use construction adhesive in thin lines and a few short screws through the board into the panel. Keep screw heads countersunk and away from where cats will stand. Leave the front edges of the shelf visible, or face them with thin strips of pallet wood.
Vary board widths and tones for a natural look. Some owners stain a few boards a shade darker; if you do, use a water-based product and let it cure fully.
Adding cat features
Turn upper cubes into cubbies with cushions cut to size. For a hiding effect, staple a fabric curtain inside the top edge. Fix a sisal mat or rope-wrapped board to the outside of one side panel, at the height your cat likes to scratch; for most cats, the bottom two cubes' height is enough.
For an extra perch, screw a pallet-board shelf with a sturdy bracket to the wall above the unit, so cats step from the top to the shelf. The cat wall shelves and window perches hub covers bracket choice.
Making the cubbies comfortable and safe
Cut foam or cushions slightly larger than the cube so they stay put without glue. Washable covers are worth the extra effort; cats shed and the occasional hairball happens. Line the back of each cubby with a scrap of felt if the shelf has thin back panels, which keeps it warmer and quieter.
If you add curtains, use a lightweight fabric hung from a slim rod or stapled tape, with no strings or long cords. Leave a gap at the bottom so a cat can see out. Many cats prefer cubbies on the higher levels, so start with the upper cubes and move cushions lower if your cat chooses differently.
Keep the cubbies away from radiators and direct sun. Shelf finishes and fabrics fade or warm up quickly in a south-facing window.
Anchoring
An upright cube shelf with cats jumping on top must be anchored to the wall. Use the restraint supplied with the shelf, fixed into a stud or with suitable wall anchors for your wall. The CPSC Anchor It campaign explains why tall furniture should be secured. The stud-safe cat tree build shows how to find studs and fix brackets.
Check the anchor every few months. Cat landings put repeated force on the top, which can loosen fixings over time.
Maintenance over the years
Check screws and the wall restraint every few months. Re-sand and touch up the finish where claws have roughened the top surface. Replace the sisal panel when it is worn; because it is fixed to the outside face with staples and glue, a new mat goes on in under an hour.
Pallet cladding is easy to repair. If one board cracks or stains, unscrew it and replace it with a spare board from the same pallets. Keep a couple of finished spares aside for this.
Wash cushion covers regularly. A clean, comfortable cubby is the part of the hack cats use most.
Finishing
Seal pallet cladding with a water-based polyurethane or hard wax oil. That stops splinters, makes the wood easier to clean and protects it from scratches. Let the finish cure for the time on the label, usually several days, before cats use the shelf.
Add felt pads under the unit to protect the floor. If the shelf stands on carpet, put a thin board underneath so it stays level.
Styling it like furniture
Treat the unit like a living room bookcase: books, plants (only cat-safe ones), and a basket or two. Cushions in neutral tones blend better than bright cat beds. Mid-century modern cat furniture ideas and modern cat living rooms have more styling tips, and cat furniture that doesn't look like cat furniture gathers more disguised designs.
IKEA hack pallet cat tower: FAQs
Which IKEA shelf works best for a cat tower?
A sturdy cube shelving unit is the usual choice: the square openings suit cat beds and baskets, and the frame is heavy and rigid enough to clad with pallet boards. A four or eight cube unit gives a good mix of cubbies and climbing levels. Always fit the wall restraint that comes with it, since cats will jump onto the top.
Is pallet wood safe for indoor cat furniture?
Yes, as long as the pallet is stamped HT for heat treatment, and the boards are cleaned, de-nailed and sanded smooth. Seal them with a water-based finish and wait until it has fully cured, usually several days, before your cats use the shelf. Reject boards that smell, show stains or mould, or come from unmarked or MB-stamped pallets.
How do I attach pallet boards to particleboard?
Use construction adhesive on the back of each board, then add short screws into the thicker panels of the shelf, such as the top and sides, not the thin back. Pre-drill and countersink the screws so the heads sit below the surface away from paws. Clamp or weight the boards while the adhesive cures to get a tight, flat fit.
Does the shelf need to be anchored?
Yes. Cats jumping onto the top create a repeated sideways force that can tip an upright shelf, especially once pallet cladding adds weight up high. Screw the restraint or a steel bracket into a wall stud, or use the right wall anchor if there is no stud. Pull-test it before letting the cats climb, then check it monthly.
How long does the pallet tower build take?
Most people finish in a weekend: one day to take apart, clean and sand the pallets, and one day to cut and fix the cladding, add the sisal and cubby cushions, and apply the finish. Allow several more days for the finish to cure before the cats use it. Extra time spent sanding makes the furniture look much more refined.
