Making sure you have quality materials and proper tools will save you time and help create a bench that lasts for years to come.

How to Build a Deck Bench with Backrest: Easy Steps

Now that we have our materials ready, let us have a look at the actual construction process. The steps for how to build a deck bench with a backrest are straightforward when broken down into manageable tasks:

Step 1: Prepare Your Materials and Plan the Design

Before you start, it’s essential to have a clear plan. Measure the dimensions of your deck to ensure the bench fits perfectly. Sketch out the design, taking note of where you will place each piece, including the backrest and support structures.

Once you have the design, make a materials list. You will need 2X4’s, 2X6’s, and 4X4’s for the frame and slats. Additionally, gather necessary tools such as screws, brackets, and clamps to aid in the assembly.

Step 2: Attach the 4X4 Posts to the Deck

Now, it’s time to secure the 4X4 posts to your deck. Begin by attaching deck tie brackets to each post.

• Place one bracket at the bottom of the post, and another a few inches higher to match your deck’s structure.
• Use deck screws to attach each bracket securely to the deck.
• Check that each post is level before proceeding to ensure the bench is stable.

Step 3: Install the Horizontal Supports

With the posts in place, the next step is to add the horizontal support pieces. Start by positioning the pieces on top of each post. Make sure they are aligned with the posts, and use deck screws to secure them firmly.

• Double-check the alignment to ensure the supports are square.
• Drill screws through the posts into the horizontal pieces.

Once this is done, the structure will have a solid foundation, providing support for the backrest and seat.

Step 4: Attach the Diagonal Supports

For additional support and stability, it’s important to install the 45-degree diagonal supports. Begin by positioning the L-brackets on the deck. Attach each bracket to the horizontal supports, ensuring the angles are correct.

After securing the brackets, proceed to fasten the diagonal supports.

Use deck screws to attach them to the brackets and horizontal supports. Be sure to pre-drill your holes to avoid damaging the wood. These angled pieces will add strength and reinforce the bench structure.

Step 5: Install the Back and Front Skirts

Next, it’s time to install the back and front skirts. These are essential for the visual appeal and structural integrity of the bench.

• Attach the back skirt to the horizontal supports using screws.
• Drill screws through the supports into the back skirt, ensuring the structure is level.
• Repeat this for the front skirt.

Take extra care to align everything, ensuring there are no gaps or misalignments that could affect the bench’s functionality.

Step 6: Mount the Back Supports

To give the bench added comfort, mount the back supports next. Clamp the pieces of the back support into place on the bench frame.

Once the pieces are securely clamped, use deck screws to attach the supports to the horizontal pieces. Ensure that the bottom of each support is flush with the horizontal support.

After securing them, add screws to the outside skirt to further reinforce the backrest.

Step 7: Install the Slats

Start by installing the seat slats on the deck bench. Begin by evenly spacing each slat, leaving a small gap between them for ventilation and drainage.

Secure each slat to the horizontal supports with deck screws, ensuring they are aligned properly for a clean and uniform look. Take care to drill the screws straight to prevent any misalignment.

Step 8: Attach the Tables and Seal

Now, focus on building the side tables.

Use scrap wood pieces to create the table structure, cutting them to fit the desired size. Secure each piece with deck screws to ensure stability. After attaching the tables, finish by sanding the entire bench and side tables.

Apply a stain or sealant to protect the wood from the elements and to improve its appearance.

With these steps completed, you’ll have a beautiful, custom bench that makes your deck more functional and comfortable for everyone!
