How To Make Garden Benches From Pallets | Easy Diy Seat

You keep wood out of the waste stream, you gain extra seating, and you can size the bench to match your patio or vegetable beds. Later in this article you will see How To Make Garden Benches From Pallets using a simple, repeatable layout. With a little planning, even a first-time DIYer can turn rough pallets into a bench that looks deliberate rather than cobbled together.

This tutorial walks through pallet selection, basic safety checks, tools, cutting layouts, assembly, and finishing. By the end, you will know how to pick safe pallets, how to break them down with minimal waste, and how to assemble a bench that can handle real outdoor use.

Planning Your Pallet Garden Bench

Before you pick up a saw, decide where the bench will live and who will sit on it. A bench along a vegetable bed calls for a different size than a reading spot under a tree. You can scale the same basic bench layout up or down to suit children, narrow balconies, or wide patios too.

Bench Size	Recommended Length	Number Of Standard Pallets*
Compact (1 person)	80–90 cm	1–2
Small (2 person)	120–130 cm	2
Medium (2–3 person)	140–160 cm	2–3
Large (3 person)	170–180 cm	3
Extra Long	190–210 cm	3–4
Corner Bench	2 x 120–140 cm	4–5
Bench With Table Arm	140–160 cm	3

Choosing Safe Pallets For Benches

The pallets you choose matter more than any other part of this project. Some pallets are heat treated with no added chemicals, while others are fumigated or have carried unknown spills. For garden furniture, pick clean, dry pallets with an HT stamp, which means the wood was heat treated, not chemically treated, under the ISPM 15 rules for pallets.

Avoid pallets marked MB for methyl bromide treatment, as this pesticide is toxic and banned for new pallets in the European Union, and skip anything with heavy staining, oil, or unknown residue on the boards. The ISPM 15 pallet marking system makes these codes easy to read, so take a minute to scan each pallet before you bring it home.

How To Make Garden Benches From Pallets Step By Step

Once you have safe pallets on hand, you can move through the build in a steady sequence: break down the pallets, cut components to size, build the frame, add the seat and backrest, then sand and seal. Working in this order helps you stay organised and makes it easier to keep track of which boards become legs, rails, and slats.

Tools And Materials You Will Need

You do not need a workshop full of gear to build a pallet bench, but a few basic tools make the job quicker and safer.

• 2–4 safe pallets (heat treated, clean, dry)
• Handsaw or circular saw with sharp blade
• Pry bar or pallet breaker and a hammer
• Drill or driver with wood bits and screwdriver bits
• Outdoor wood screws (5–6 cm and 7–8 cm lengths)
• Measuring tape, pencil, and builder’s square
• Safety glasses, gloves, and hearing protection
• Sandpaper or sander (80, 120, and 180 grit)
• Outdoor wood stain, paint, or clear sealer

Breaking Down Pallets Without Splitting Boards

Start by cutting or prying apart your pallets so you can reuse as many full boards as possible. Sawing directly along the stringers, just outside the nails, is the fastest method. You lose a little length at each end, but you avoid the frustration of split boards and bent nails.

Cutting Bench Parts From Pallet Boards

With a stack of loose boards ready, lay them out and mark lengths for legs, front and back rails, seat slats, and backrest slats. For a typical two-person bench around 120–130 cm long, plan on four legs, two long front rails, two long back rails, and at least six to eight seat slats spaced with small gaps between.

Cut parts in batches so matching pieces stay the same length. When you cut the legs, you can double up boards and screw them together later to form stronger posts.

Assembling A Strong Bench Frame

Begin the frame by attaching front and back rails to the legs. Set the lower rails at the height you want for the seat front, then add upper rails to tie the frame together. Use long wood screws and pre-drill near board edges to avoid splits. Check that each side stands square before you join the two sides with short cross pieces near the seat front and back.

Once the rectangle of the seat frame is solid, add extra blocks across the middle as hidden support. These short blocks carry some of the weight and keep the seat from sagging when someone sits near the centre.

Adding Seat Slats And Backrest

Lay the seat slats across the frame with an even gap between each board. A scrap of pallet wood used as a spacer works well. Start with the front and back slats, then fill in the middle. Stand back and check that the gaps look even from a distance before you drive all the screws home.

For the backrest, fix back posts to the rear of the seat frame, leaning them slightly so the backrest tilts. Then attach horizontal slats at a comfortable height, leaving a small gap between them. You can run the slats all the way down, or stop them partway down the back for a lighter look.

Shaping And Sanding For Comfort

Freshly cut pallet boards are rough and full of splinters, so take time to soften every surface your legs and hands will touch. Round over seat front edges with a plane or coarse sandpaper, then smooth the top of each slat. Pay special attention to arm rests and the top edge of the backrest.

Work through sanding grits in stages: start with 80 for rough shaping, shift to 120 for overall smoothing, and finish with 180 on arm rests and seat boards. You do not need a perfect furniture finish for a garden bench, but you do want to remove sharp corners and loose fibres that snag clothing.

Protecting Pallet Wood For Outdoor Use

Even the strongest bench will not last long outside if the wood soaks up water and stays damp. A clear outdoor sealer keeps the pallet look, while stain or paint gives more colour and extra protection. Many pallet builders prefer a film-forming finish that resists moisture on the surface; others choose an oil that soaks into the grain for a softer feel.

Before you coat the bench, blow or brush off sanding dust, and let the wood dry fully under cover if the pallets were stored outdoors. Then apply finish to every surface you can reach, including the underside and the bottoms of the legs. Seal any cut ends carefully, since end grain drinks in water faster than the rest of the board.

Finish Type	Look And Feel	Care Tips
Clear Exterior Sealer	Natural wood colour, slight sheen	Recoat every 1–2 years; clean dust and algae first
Outdoor Wood Stain	Transparent or semi-opaque colour	Test colour on scrap; refresh when fading or drying out
Exterior Paint	Solid colour, most coverage	Use primer on bare pallet wood; touch up chips early
Oil Finish	Soft, low-sheen, shows grain	Apply thin coats; repeat more often in wet climates
Varnish Or Yacht Varnish	Glossy and smooth	Best under cover; sand lightly between coats

Customising Your Pallet Garden Bench

Once the basic bench stands solid, you can tweak it to suit your garden. Extra boards along the sides can turn into arm rests wide enough for a mug or small plant pot. A narrow shelf below the seat holds gardening gloves or hand tools. Corner benches built from two frames at right angles help frame a fire pit or outdoor table.

Safety Checks Before You Sit Down

Before you call the project finished, give the bench a slow, methodical safety check. Press on the backrest to see if anything flexes more than it should. Rock the bench gently side to side and front to back. Listen for creaks near joints or legs; extra screws or a diagonal brace may help stiffen a shaky frame.

Run your hands lightly along the seat and arm rests to check for splinters you might have missed while sanding. Look for any nails left in place from the original pallets and either remove them or punch them below the surface. If the bench will live on soil or grass, slip concrete pavers or bricks under the legs so they stay dry and last longer.

Once you have built one bench, repeating the same method for a second or third build feels faster and smoother. You can adjust the backrest angle, arm width, or overall length with each version. With practice, you will treat How To Make Garden Benches From Pallets as a flexible pattern rather than a single fixed design, and your garden will gain sturdy seating made almost entirely from reclaimed wood.
