A pallet garden bench can be built from two clean pallets, exterior screws, and straight cuts for a steady seat you’ll use all season.
A pallet bench is one of those builds that feels doable, even if you don’t own a full shop. The wood is thick, the parts are forgiving, and the finished bench has real weight behind it.
Here’s how to make a pallet garden bench?: pick pallets, cut square, screw a stiff frame, brace the back, then seal the wood rain-ready.
Project Snapshot And Cut Plan Table
Pick your bench size first. It keeps the cuts clean and stops mid-build second guessing.
| Build Item | Target Spec | Notes That Save Time |
|---|---|---|
| Bench width | 100–120 cm | Choose a width that fits between planters or along a wall. |
| Seat height | 42–45 cm | Close to a dining chair; add a pad if you want more height. |
| Seat depth | 45–50 cm | Keep enough depth for thighs, plus room for a backrest lean. |
| Backrest height | 35–45 cm | Measured from seat surface; taller suits upright sitting. |
| Backrest lean | 10–15° | Use a scrap spacer while fastening so both sides match. |
| Fasteners | 60–75 mm exterior screws | Coated or stainless handles rain better; pre-drill near ends. |
| Leg style | 4×4 blocks or laminated stringers | Wider feet sit better on gravel or soil. |
| Build time | 3–6 hours | Nail removal and sanding can take longer than the assembly. |
Choosing Pallets That Are Clean And Worth Using
Start with good wood. It decides how the bench feels in your hands and how it holds up in rain.
Read The Stamp And Skip Questionable Pallets
Look for pallets stamped “HT” (heat treated). That stamp is part of the trade marking system used for wood packaging. If you want to verify what the stamp means, the EU page on ISPM15 marking requirements explains the mark and the treatments listed.
Pass on pallets with oily stains, sharp odors, or unknown spills. Skip boards that are split through the grain, soft, or badly warped.
Pick Pallets With Straight Stringers
The “stringers” are the thick runners under the slats. Straight stringers give you a square seat frame and better screw bite. Two pallets with similar board thickness keep your build calm.
Tools And Materials You’ll Use On This Build
You don’t need fancy gear. If you can measure, cut, drill, and sand, you can build this bench.
Tools
- Measuring tape, pencil, and a square
- Pry bar or cat’s paw, plus pliers
- Circular saw or jigsaw
- Drill/driver with bits and a countersink
- Sander or sanding block (80, 120, 180 grit)
- Two clamps (nice to have)
Tip: Mark both sides before cutting. When slats vary in thickness, keep thicker pieces for legs and braces, thinner ones for back slats only.
Materials
- Two heat-treated pallets
- Exterior screws: 60–75 mm and 35–45 mm
- Exterior wood glue (optional)
- Outdoor finish: deck oil, exterior stain, or paint
- Felt pads or flat pavers for the feet
How To Make A Pallet Garden Bench? Step By Step Build
Read this once, then build in order. The bench gets its strength from a square seat frame and a braced backrest.
Step 1: Break Down Pallets Without Cracking Slats
Lay the pallet flat. Slide a pry bar under a slat near a nail line and lift a little. Move a few centimeters and lift again. Small lifts reduce splitting. When a slat loosens, pull nails with pliers or drive them back through with a punch.
If a slat starts to crack, stop and work that nail point from the other side. It’s slower, but you’ll save the board.
Step 2: Choose A Seat Base Style
- One-piece seat deck: Keep one pallet mostly intact, trim to width, and use it as the seat platform.
- Framed seat deck: Build a rectangle from stringers, then screw slats on top with even gaps.
The one-piece seat deck is fast. The framed seat deck lets you dial the seat depth and replace slats with cleaner boards.
Step 3: Cut The Seat To Size
Mark width and depth on the seat deck. Use a square so your lines stay true. Cut slowly and hold both sides of the piece so the offcut doesn’t tear a slat at the end.
Dry-fit the seat where it will live. A bench that looks fine on the driveway can feel too wide once it’s tucked between pots.
Step 4: Build Legs That Sit Flat
Two common leg builds work well with pallet lumber:
- Block legs: Cut four equal blocks from thick stringer wood and screw them under the corners.
- Laminated legs: Stack two or three stringer pieces per leg, glue and screw them into a single post.
Flip the seat upside down and clamp the legs in place. Drill pilot holes. Drive long screws through the seat frame into each leg. Add a second screw line so the leg can’t twist.
Step 5: Add A Backrest With Side Braces
Cut a backrest panel from the second pallet. A slat section works, or a framed panel if you want cleaner edges. Hold it behind the seat and set the lean with a spacer block.
Screw the backrest into the rear edge of the seat frame. Then add two side braces that run from the seat frame up to the backrest. Use long screws and pre-drill to reduce splitting.
Step 6: Add Armrests (Optional)
Armrests make the bench feel finished. Cut two boards and mount each one on a front bracket and a rear brace. Measure from the seat surface so both sides sit level.
Step 7: Tighten And Test
Set the bench on a flat surface and sit down gently. If it rocks, loosen one leg, slip a thin shim under the low corner, then retighten. If the backrest flexes, add another brace or a cross rail across the backrest.
Making A Pallet Garden Bench With Backrest And Storage
Storage is a clean add-on that keeps the bench looking tidy. Build a framed seat deck, then leave the rear slats unattached on one side so they lift like a lid. Add a stop block inside the box so the lid sits flush when closed.
Use this space for light items like cushions. Heavy loads can rack the frame unless you thicken the corner blocks.
Sanding, Edges, And Comfort Tweaks
Pallet wood can be rough. A short sanding routine changes the whole feel.
Sand In Three Passes
Start with 80 grit to remove splinters and grime. Move to 120 grit to smooth the touch points: the seat front edge, armrests, and the top slats. Finish with 180 grit where skin will rest.
Soften The Front Edge
Round the seat front edge with a sander. That small curve stops the sharp-board feeling behind your knees.
Leave Drainage Gaps
Leave small gaps between slats so rain can drain. If your slats sit tight, trim a few millimeters off each and reinstall with a spacer.
Finish Choices And Upkeep Table
Pick a finish based on sun, rain, and how much touch-up you’re willing to do.
| Finish Type | Best Spot | Upkeep Rhythm |
|---|---|---|
| Penetrating deck oil | Open air, easy refresh | Wipe on yearly; spot-fix scuffs when they show. |
| Exterior stain | Sun-heavy patios | Recoat after a light sand on a 2–3 year cycle. |
| Exterior paint | Roofed spots, bold color | Touch up chips; repaint when edges wear. |
| Marine spar varnish | Rain splash zones | Multiple coats; refresh when the sheen thins. |
| Clear water sealer | Bench under a roof | Fast coat yearly; keeps a raw-wood look. |
| None (bare wood) | Short-term seating | Wood grays and roughens; sand before use. |
| Wax or indoor oil | Indoor-only benches | Skip outdoors; it washes out and grabs dirt. |
Shop Habits For Cleaner Cuts
Wear eye protection when cutting or drilling. OSHA’s eye and face protection standard lists when protection is required in work settings, and it’s a solid baseline for DIY work too.
Scan boards for hidden nails before cutting. A small magnet can find nail heads under dirt. Clamp parts before drilling so the bit doesn’t skate across the grain.
If a pallet has old paint and you plan to sand it, test the coating first when the source is unknown. Fine dust spreads fast and lingers on nearby surfaces.
Common Bench Problems And Quick Fixes
Seat Feels Soft In The Middle
Add a center leg or a lead stretcher under the seat. A single board running front-to-back under the middle stiffens the deck fast.
Backrest Shakes When You Lean
Add a second pair of braces, or add a horizontal rail across the backrest and screw it into several slats. Spread the screws across more wood.
Bench Rocks On Stone
Use wide feet and add felt pads. Set the bench in place and shim the low corner, then trim the shim flush.
Screw Heads Strip
Switch to a fresh bit and keep firm pressure in line with the screw. If a hole is blown out, fill it with glued-in toothpicks, let it set, then re-drive the screw.
Final Fit And Outdoor Placement
Put the bench where you’ll sit most. Check the feel. If the back feels too upright, loosen the backrest screws, add a thicker spacer at the bottom, and retighten. If the seat feels low, place the bench on flat pavers to gain height without rebuilding legs.
Once you’ve built one, you’ll spot ways to tweak the next one: a wider armrest, a deeper seat, or a cleaner finish. When a friend asks how to make a pallet garden bench?, you’ll have a clear plan to share.
