How to Build a Bench Seat for a Dining Table: A Step-by-Step DIY Guide
A bench seat for a dining table is a fantastic way to add extra seating, optimize a small space, and create a cozy dining area. Whether you’re looking for a built-in dining bench, a storage bench, or a freestanding bench, this DIY guide will walk you through the process.
Using wood screws, pocket holes, MDF boards, and other materials, you can create a sturdy and stylish bench seat that complements your dining table.
1. Planning Your DIY Bench Seat Build
Before you start cutting wood, it’s essential to plan your bench frame, bench seat top, and dimensions to ensure a perfect fit for your dining table. Consider whether you want a banquette bench, a corner bench, or a built-in bench to best suit your space.
Choosing similar materials to your dining table will create a seamless look. For instance, if your farmhouse dining table is made of walnut wood, using wood glue and trim pieces can help achieve a cohesive style.

3. Cutting the Bench Frame & Top Pieces
Begin by cutting the bench frame, bench seat top, and side of the bench to your desired dimensions. Use a circular saw for straight cuts and a miter saw for angled cuts if needed.
If using MDF boards or walnut wood, ensure the material is properly measured to avoid unnecessary waste.
When cutting the top piece, ensure that the bench top aligns properly with your dining table to create a comfortable seating height.
The standard seat height for a dining bench is between 17-19 inches, so adjust accordingly if using cushions or padding.
If your dining area has an existing farmhouse dining table, matching the bench seat height will create a seamless and cohesive look.
Double-check all measurements before making cuts, as precision is key to a sturdy and balanced build. If you’re building a corner bench, consider how the side of the bench will meet at a right angle and adjust the top end apron accordingly.
4. Assembling the Bench Frame
The bench frame is the most critical part of the build, as it supports the entire structure. Secure the frame pieces using pocket hole screws and wood glue for added durability. If working with MDF boards or similar materials, apply wood glue generously to ensure strong adhesion before screwing pieces together.
Using a parallel clamp will help keep the frame square while assembling. This prevents shifting and ensures that the bench seat bottom and top of the bench remain level.
If you’re building a storage bench, consider reinforcing the bottom runners to handle additional weight from stored items.
Reinforce the long apron and top end apron to prevent wobbling. Adding connector blocks at the side of the bench helps distribute weight evenly and prevents long-term structural issues.
If your bench will be against a wall, securing the back of the bench with screws into studs can provide extra stability.

5. Attaching the Bench Legs
For added strength, attach the bench legs using wood screws and mm screws. Ensure the tops of the legs are flush with the bench seat bottom to prevent rocking or uneven seating. Properly secured bench legs will help prevent movement when weight is applied.
A countersink bit is useful for preventing the screws from sticking out, creating a smoother finish that’s easier to paint or stain. If using trim pieces, make sure they align with the bench legs to give a polished look.
If you’re making a built-in bench, secure the legs to the wall using connector blocks for extra stability. If placing the bench seat in a small space, make sure the legs don’t obstruct legroom or dining chairs.
6. Reinforcing with Half-Lap Wood Joinery
For a more durable structure, consider using half-lap wood joinery. This method involves interlocking the wood by cutting notches at connection points, making the bench frame stronger without relying solely on wood screws.
If you’re unfamiliar with half-lap joints, many free plans online can guide you through the process. A half-lap joint is a great way to add strength while maintaining a sleek design, preventing bulky connections.
For best results, use clamps and wood glue when assembling half-lap joints. Once dry, reinforce the joints with pocket hole screws for added security. This technique is especially useful if your bench frame is supporting heavy weight, such as in a banquette bench setup.
7. Installing the Bench Seat & Storage Option
Once the frame and legs are secure, it’s time to attach the seat of the bench. Use wood glue along the edges and secure with trim pieces to enhance durability. If you want a softer feel, consider adding a foam piece before upholstering the seat.
If creating a storage bench, use hinges to make the top of the bench openable. This is a good idea for small dining area needing additional storage for table linens, extra seating cushions, or small kitchen items.
For added stability, reinforce the back of the bench and side of the bench with wood screws. If your bench seat top extends beyond the bench frame, ensure it is properly supported with bottom runners or additional bracing.
8. Sanding & Smoothing the Bench
For a professional finish, sand the whole thing using grit sandpaper. This will help smooth out rough edges and create a satin finish when painting or staining.
A clean rag can be used to remove dust before applying a paint brush or stain. If you plan to paint the bench, using MDF boards will provide a smooth surface that absorbs paint evenly. If staining, consider walnut wood for a rich, classic look.
If you prefer a modern aesthetic, a satin finish can give the bench top a sleek appearance. Sealing the bench with a clear coat will protect the wood and keep the finish looking new.

9. Installing the Bench in Your Dining Area
For a built-in kitchen bench, secure it to the wall using connector blocks. If it’s a freestanding dining bench, ensure that the seat heights align with your dining room table. Standard bench seat height is between 17-19 inches, so adjust based on the farmhouse dining table or kitchen table height.
Positioning the bench seat at the side of the table is a great way to create extra seating without cluttering the space. If your dining area is a small space, placing the bench against a wall can free up room for additional chairs.
For an eat-in kitchen, a built-in bench provides a cozy and functional alternative to traditional seating. Consider adding IKEA kitchen cabinets underneath for extra storage.
10. Adding the Final Details
Before calling the project complete, check all screws and pocket holes for tightness. Use wood filler to cover any exposed holes for a clean look. This is especially important if you’re staining the bench frame, as gaps can become visible.
The last step is applying a satin finish or stain to match your farmhouse dining table. If you used MDF boards, painting may be a better option than staining. If using walnut wood, a clear protective coat will enhance its natural beauty.
Adding a foam piece to the bench seat top will increase comfort and create a more inviting look. A built-in piece can also be customized with trim pieces to match existing decor.
