Prep First: Cut, Sand, and Stain

Before we build, we prep—because nothing’s worse than realizing halfway through that you forgot to sand your armrests.

Steps

1. Cut all boards according to the cutting list above.
2. Sand everything with 80-grit sandpaper. Smooth edges are happy edges—especially for armrests!
3. Gently round off the front edge of your 22.5″ armrest pieces.
4. Stain all sides, including the end grains. Go for two coats, letting each dry completely between applications.

Boards laid out in neat stacks on a sunny patio, a soft brush dragging stain across the grain while a light breeze carries the scent of fresh wood and summer dreams.

Build the Seat Frame

This is the backbone of your bench—and you’ll feel pretty empowered watching it come together.

Steps

1. Drill pocket holes into both ends of the 16.5″ boards.
2. Join them between the 52″ side pieces using clamps for alignment.
3. Screw everything together tightly to form a sturdy rectangle.

That first moment of structure—your rectangular frame resting proudly on the work table, looking like it’s already halfway to being a bench.

Add the Seat Boards

Time to give this bench its cozy landing spot.

Steps

1. Pre-drill and countersink holes in each 51″ seat board to avoid splitting.
2. Use a jig or scrap wood to guide consistent hole placement.
3. Install each board across the top of the frame with a 0.5″ gap between them.
4. Use spacers between the boards to keep everything even.

The top of your bench starting to look real—plank by plank, those gorgeous wood tones glowing in the light, gaps perfectly spaced like a dream.

Add Front Legs and Armrests

Let’s give this beauty some legs to stand on (literally).

Steps

1. Drill pocket holes on one side of each 24″ front leg.
2. Attach the 22.5″ armrests with a 1.5″ overhang in front and the rounded edge facing forward.
3. Screw the front legs and armrests together, pocket holes facing the back.
4. Attach each front leg to the seat frame, measuring 13″ from the bottom of the leg to the bottom of the frame. Check for square before tightening.

Picture This

Two solid front legs standing tall, arms outstretched, looking like the beginnings of a bench that’s ready to welcome you home.

Install the Back Legs

This is where comfort really starts to happen—your back will thank you later.

Steps

1. Position each 32″ back leg so that the seat frame sits 13″ up from the ground.
2. Screw through the back of each leg into the seat frame.
3. Measure 6.5″ from the top of the back leg to the top of the armrest.
4. Drive two screws through the back leg into the side of the armrest.

Picture This

The frame’s taking shape like a real bench now, back legs propped perfectly, strong and graceful—like it’s always been there waiting for you.

Create the Backrest Boards

Now it’s time to design the cozy support for those leisurely afternoons.

Steps

1. Drill two pocket holes in one side of each 19″ backrest board.
2. On your 2×6 top cap (52″), mark 3.5″ from each end to leave space for the legs.
3. Then mark 2-7/16″ gaps between each board placement.
4. Clamp each board in place following the marked spacing.
5. Screw each board into the 2×6 top cap with pocket hole screws.

Picture This

The top rail coming together like a puzzle, each slat placed just so—clean lines and precision that feel as lovely as they look.

Attach the Backrest

Almost there—this is the part that makes your bench super inviting.

Steps

1. Drill two pocket holes into the top back of each back leg.
2. Position the top cap with attached backrest boards on top of the back legs, flush with the sides.
3. Clamp and screw the top cap into the legs.
4. Add two screws through the bottoms of the backrest boards into the seat frame for added support.

Picture This

That final satisfying clunk of the drill, the backrest snug in place, and the whole bench standing proud like it’s been waiting to star in your next garden party.

The Finishing Touches

You made it. Now let’s wrap up this beauty with care.

Steps

1. Touch up any exposed screw holes or raw edges with stain.
2. Optional: insert and stain pocket hole plugs for a clean finish.
3. Let the stain cure completely before using.
4. Add cushions, a throw, or even a little side table if you want to go all out.

Picture This

A finished bench gleaming under the soft light of golden hour, a patterned cushion tossed on top, ready for its first cup of coffee or heartfelt conversation.

Build It, Love It, Lounge On It
