If you love the cozy comfort of restaurant booths but balk at the price tag, there’s a simple hack that turns IKEA shelving into a stylish, budget-friendly banquette. This project swaps expensive carpentry and complex upholstery for modular pieces, basic tools, and a few finishing touches. The result is a comfortable, storage-ready bench that fits corners and small dining nooks with ease.
Why an IKEA-based banquette makes sense for small homes

Banquettes do more than look inviting. They save floor space, boost seating capacity, and often add hidden storage. But factory-made units can cost hundreds. Converting IKEA KALLAX shelving into a bench gives you the same benefits at a fraction of the cost.
- Space efficiency: An L-shaped banquette maximizes corners and opens up tight rooms.
- Custom sizing: Combine different KALLAX widths to match your table and layout.
- Built-in storage: The shelf cubbies become accessible storage without extra furniture.
- Lower cost: Parts and materials usually add up far less than a ready-made banquette.
What to buy: KALLAX units, supplies, and tools
Planning ahead saves time and prevents mid-build trips to the store. Below is a practical shopping list for the KALLAX banquette approach.
- KALLAX shelf units (choose 2- or 4-cube options to fit your space)
- Plywood sheets for the seat top and lid
- Piano hinges to create lift-up lids for hidden storage
- Finishing caulk and paint in your chosen color
- Trim or baseboard to frame the bench and make it look built-in
- Long bench cushion or custom-made foam and fabric
Essential tools
- Table saw or circular saw for cutting plywood
- Miter saw for trim and precise angles
- Power drill and screws
- Brad nailer or finish nails for trim work
- Measuring tape, level, and pencil
Build steps: from KALLAX boxes to a finished corner bench
Follow these practical steps to transform KALLAX units into a corner banquette with storage lids.
- Measure the nook: Record wall lengths, table clearance, and desired bench depth.
- Choose KALLAX sizes: Pick 2-cube (about 30 in.) or 4-cube (about 58 in.) units, or mix them to hit your layout.
- Lay units on their sides: Turn the shelves so the cubbies form the front-facing storage pockets.
- Connect and stabilize: Align units in an L shape and anchor them to the wall with the included anti-tip kit.
- Create a hinged lid: Cut plywood to span the top. Attach piano hinges along the back edge so lids lift to reveal cubbies.
- Reinforce the seat: Add cleats or a supporting frame under the plywood for weight distribution.
- Finish edges and trim: Fill gaps with caulk, then apply baseboard or trim to make the bench read as built-in.
- Paint and cushion: Prime and paint the unit. Top with a long cushion or custom foam wrapped in fabric.
Design choices, cost savings, and pro tips
Small decisions change the finished look and function. Here are practical ideas to help the build feel intentional.
- Open vs. hidden cubbies: Leave cube fronts open for quick access, or add lids for concealed storage.
- Color and hardware: Paint the exterior to match your trim, and choose subtle hinges for a refined finish.
- Seat height: KALLAX turned on its side is about 16 in. high. Add a thick cushion to reach a comfortable dining height.
- Safety first: Always secure tall pieces to the wall with anti-tip hardware.
- Budget snapshot: Typical materials can run a few hundred dollars. That often beats comparable retail banquettes by a large margin.
- Customization: Mix unit sizes to craft a precise L-shape or straight bench that fits your space.
Finishing touches that elevate a DIY banquette
Small refinements make the project feel like custom carpentry. Use a smooth bead of caulk where the bench meets walls to hide gaps. Add painted baseboard trim for continuity with existing molding. Top the bench with a tailored cushion in a durable fabric to increase comfort and style. With these details, a simple IKEA hack becomes a polished, functional focal point for the room.
