Quick answer: A beginner multi-level cat tower for a bedroom needs a 50 x 50 cm plywood base, one sturdy central post and three platforms at about 40, 80 and 120 cm. Put felt pads under the base to protect cork tiles, add a wall strap at the top, and the tower will stay quiet and stable through night-time jumps.
Bedrooms are where many cats spend the night, and a tower beside the bed or window gives them their own high spot instead of your pillow. A bedroom build has its own rules, though: it should be quiet, compact, and gentle on the floor, especially soft flooring like cork.
This is a first-project version. For taller designs, condos and space-saving towers, see our DIY cat tree hub.
Why a Bedroom Tower Is Different
In a living room, a tower can be large and a little noisy. In a bedroom, a creak or thump at 3 a.m. matters. Every joint has to be tight, every platform has to sit flat, and the base has to grip the floor without scratching it.
Space is also tighter. Most bedrooms have one good spot, often beside a window or in the corner between the bed and the wall, and the tower has to fit there without blocking a wardrobe door.
Sizing the Footprint
A 50 x 50 cm base suits a tower of about 120 cm for an average adult cat. As a rough rule, keep the base width at no less than about 40 per cent of the tower height. At 120 cm, that is 48 cm, so 50 cm gives a small margin.
Measure your chosen corner before cutting anything, and leave at least 10 cm from the wall so the cat can jump onto the top platform without hitting its head on a shelf or window frame.
Protecting Cork Tiles
Cork is soft and dents under point loads. A plywood base spreads the weight evenly, which is much kinder than four narrow feet. Stick wide felt pads under each corner and one in the middle, and check them every few months, since grit trapped under a pad can scratch the cork.
Avoid rubber feet on cork; some rubber compounds can leave marks over time. Felt is the safer choice.
Cut List for a 120 cm Tower
| Part | Material | Size | Quantity |
|---|---|---|---|
| Base | 18 mm plywood | 50 x 50 cm | 1 |
| Central post | Pine, 9 x 9 cm | 115 cm | 1 |
| Lower platform | 18 mm plywood | 40 x 35 cm | 1 |
| Middle platform | 18 mm plywood | 40 x 35 cm | 1 |
| Top platform | 18 mm plywood | 45 x 40 cm | 1 |
| Platform supports | Pine, 4.5 x 4.5 cm | 30 cm | 3 |
The base plus the 115 cm post plus the 18 mm top platform comes to about 120 cm in total. Ask the timber yard to cut the plywood if you do not own a saw; most will do straight cuts for a small fee.
Platform Heights That Suit a First Build
Set the lower platform at about 40 cm, the middle at 80 cm and the top at 120 cm. Steps of 40 cm are easy for adult cats and allow a kitten or older cat to use the lower levels. Alternate the platforms around the post, so the cat jumps in a spiral rather than straight up.
Our senior-friendly cat tree guide reduces the steps to 25 to 30 cm for older cats with stiff joints.
Assembly Order
Fix the post to the base first, using two long wood screws driven up through the base into the post end, plus a pair of steel angle brackets. Then fit the platform supports to the post, check each is level, and screw the platforms on from above.
Pre-drill every hole. Pine splits easily near the ends, and a split joint is the most common source of creaking later.
Wrapping the Post
Wrap the post in 8 or 10 mm sisal rope from the base up to the lower platform, where most scratching happens. Staple the start and end under a platform, where the cat cannot reach them. Wind the rope tightly and push each turn down against the last to avoid gaps.
San Francisco SPCA on scratching posts recommends sisal and a solid, stable post for this reason.
Covering the Platforms
Cover the platforms in offcuts of low-pile carpet or felt, glued and stapled from underneath. A soft surface muffles landing noise, which matters in a bedroom. Leave the edges slightly overhanging to soften the corners.
Choose a water-based adhesive and let it air out for a few days before the cat uses the tower. EPA on VOCs and indoor air explains why low-VOC products are a better choice for bedrooms.
Keeping Night-Time Jumps Quiet
Tighten every screw after the first week, when the timber has settled. Put a thin layer of felt between each platform and its support to stop wood-on-wood clicks. If the tower knocks against the wall when the cat lands on top, add a rubber bumper where it touches.
Adding a Wall Strap
Even a well-built tower can sway when a cat launches off the top platform. A furniture strap from the back of the top platform to a wall stud stops that movement. The fixing is small and easy to fill if you move out.
Our anchoring safety checklist shows how to fix a strap correctly, and our stud-safe tree build explains how to find a stud behind plasterboard.
Testing Before the First Night
Push firmly on the top platform from each side. There should be no rocking and no creaking. Then leave the tower for a day with a few treats on each level, so the cat can explore it while you are around.
Our stability test guide gives a quick routine to repeat every month.
Matching the Tower to the Bedroom
Pale pine and plywood suit most bedroom styles, especially with a clear water-based finish on exposed edges. A neutral sisal and carpet in grey or oatmeal keeps it calm. Our guide to cat furniture that does not look like cat furniture has more ideas for making a tower blend in.
Tools You Need for This Tower
A drill-driver, a set of wood drill bits, a tape measure, a square, a staple gun and a utility knife are enough. If the timber yard cuts the plywood and the post to length, you will not need a saw at all. A spirit level helps when fitting the platform supports, because a platform that slopes even slightly feels unsteady to a cat landing on it.
Work on a dust sheet rather than straight on the cork, and keep screws in a dish so none end up on the floor where a cat could find them.
Choosing the Plywood and Pine
Buy 18 mm plywood with at least one smooth face and no large voids along the edges, since voids weaken screw fixings. For the post, choose straight pine with few knots, especially near the ends where the screws go. Sight along the length before buying; a bowed post makes every platform sit at a slight angle.
A Note on Windows and Blinds
If the tower sits beside a window, tie blind cords out of reach and check that any opening window has a secure screen. Cats on high platforms often press against glass and screens to watch birds outside.
Bedroom Tower Build Questions
How big should the base of a 120 cm cat tower be?
About 50 x 50 cm. A useful rule is to keep the base width at no less than about 40 per cent of the tower's height, which is 48 cm for a 120 cm tower. A plywood base of that size also spreads the load, which protects soft floors like cork.
Will a cat tower damage cork flooring?
It can if the weight sits on small feet. A solid plywood base spreads the load, and wide felt pads under each corner and in the middle protect the surface. Check the pads every few months, because grit trapped underneath can scratch cork.
What platform heights are best for a beginner tower?
Around 40, 80 and 120 cm suit most adult cats, giving even 40 cm steps. Arrange the platforms in a spiral around the post. For older cats or kittens, reduce the steps to about 25 to 30 cm and add an extra platform.
How do I stop a cat tower creaking at night?
Pre-drill every screw hole so the pine does not split, tighten all screws after the first week, and put a thin felt layer between each platform and its support. If the tower knocks the wall, add a rubber bumper at the contact point.
Do I need to strap a 120 cm cat tower to the wall?
It is strongly recommended. A cat jumping off the top platform pushes the tower sideways, and a strap fixed to a wall stud stops that movement. The fixing is small, and the hole is easy to fill if you move later.
