If you want to learn more about how to build a large double chair bench, you have to take a close look over the free plans in the article. This project comes with 3D diagrams, full Cut and Shopping lists, so you can build this outdoor bench with backrest and a middle table.

If you want to get the job done in a professional manner, we recommend you to plan everything with attention, as to prevent costly mistakes and to build a professional garden bench.

Made from this plan

Step 1: Building the frame of the bench

Seat-frame

First of all we need to build the components for the seat frame. Use a miter saw to make the 15 degree angle cut. Smooth the edges flush with sandpaper.

Next, we need to assemble the seat frame as shown in the diagram. Drill pilot holes through the 68″ long boards and insert 3 1/2″ screws into the perpendicular components. Make sure the corners are square and leave no gaps between the components.

Build the legs and the supports for the side frames from 2×4 lumber. Use a miter saw to make 15 degree cuts, as shown in the diagram. Lay everything on a level surface.

Assembling-the-side-frames-for-the-garden-bench

Attach the support to the legs, drill plot holes and insert at least 2 screws for each joint.

Step 2: Assembling the frame

Assembling-the-frame-of-the-double-chair-bench

Attach the side frames to the seat frame of the large garden bench. Plumb the side frames and make sure the corners are square. Clamp the side frames to the seat frame, drill pilot holes through the seat frame and insert 2 1/2″ screws into the legs. Use at least 2 screws for each joint.

Step 3: Attaching the backrest

Attaching-the-backrest-supports

Use 2×4 lumber for the backrest. Round the exposed corner of the backrests with a jigsaw and smooth the edges. Fit the supports to the seat frame and clamp them into place tightly. Drill pilot holes through the supports and insert 2 1/2″ screws into the seat frame.

Attach the 1×4 boards to the backrest of the outdoor bench. Place 1/2″ plywood between the boards to create even gaps.

Fitting the seat slats

Attach the 1×4 boards to the seat frame. Place a piece of 1/2″ plywood between the slats to create even gaps. Drill pilot holes and insert 1 5/8″ screws to secure the boards into place. Use at least 2 screws for each joint.

Attaching-the-armrests

Use 1×4 lumber for the armrests. Use jigsaw to make the cuts to the armrests.

Step 4: Building the table of the double bench

Fitting-the-middle-legs-for-the-table

Use 2×4 lumber for the table legs. Attach the legs to the seat frame and clamp them into place tightly. Drill pilot holes and insert 2 1/2″ screws to lock them into place tightly. Plumb the legs vertically with a spirit level.

Table-frame

Fit the 2×4 supports to the top of the middle legs. Use a spirit level to check if the supports are perfectly horizontal. Drill pilot holes through the supports and insert 2 1/2″ screws to lock them into place tightly.

Fitting-the-table-slats

Attach the 1×6 slats to the supports, as shown in the plans. Place a piece of 1/4″ plywood between the slats to create even gaps. Drill pilot holes before inserting the 1 5/8″ screws into the slats.

Last but not least, you need to take care of the finishing touches. Double check all the joints and make sure the bench is sturdy. Fill the holes with wood putty. Next, used a sander to smooth the bench and the edges. Since you are here you should also take a look over these simple double chair bench plans.
