Pallet furniture works because pallets are already built to stack and move, so the frame is there—you just add a cushion or sand it smooth

A wooden pallet is a flat platform made of boards nailed to cross-beams, designed to hold freight. That same structure makes it straightforward to turn into a bench, table, or lounger without cutting much wood or buying expensive hardware. The pallets themselves cost nothing to free (ask at warehouses, garden centers, or loading docks) or $5 to $15 each if you buy them new. You will need sandpaper, wood stain or paint, outdoor cushions, and basic tools: a drill, saw, and wrench or socket set.

The catch is that not all pallets are safe. Pallets marked with "HT" (heat-treated) are fine for outdoor furniture. Pallets marked "MB" (methyl bromide) were treated with pesticide and should not be used indoors or where food sits, though some people use them outside. If a pallet has no mark or you cannot read it, assume it held chemicals and skip it. Inspect any pallet for rot, deep cracks, or nails that stick up—these are signs it will not hold weight safely.

Key Takeaways

  • Heat-treated pallets marked "HT" are safe for outdoor furniture; pallets marked "MB" should be avoided or used only outside, away from where people sit regularly.
  • A basic pallet bench or table requires two to four pallets, sandpaper, wood finish, and a drill—no advanced carpentry skills needed.
  • Sanding and sealing the wood protects it from weather and splinters, and takes most of the time in the build.
  • Outdoor cushions, casters (wheels), or metal brackets let you customize the piece for comfort and mobility without building from scratch.
  • Pallets are heaviest when stacked; use a dolly or recruit help to move them before assembly.

Choosing and Preparing Pallets

Start by finding pallets that are roughly the same size and condition. Standard pallets are 40 by 48 inches, but sizes vary. Lay them flat and check for soft spots by pressing a screwdriver into the wood—if it sinks easily, the wood is rotting and will not hold weight. Look for pallets with boards that are not warped or split. If boards are loose, tap the nails back in with a hammer or drill them out and replace them with galvanized screws (which resist rust better than regular nails).

Once you have your pallets, move them to a flat work surface—a driveway or garage floor works well. Use a dolly if you have one; pallets are awkward and heavy when stacked. Lay them flat and inspect the top and bottom surfaces. If the top is rough or has stains, you will sand it. If the bottom has nails or bolts sticking out, grind them down or remove them so the finished piece sits flat and does not snag clothing or skin.

Disassemble pallets only if you need individual boards for a specific design—it is time-consuming and usually not worth it. Most pallet projects use the pallet as-is, which is the whole point.

Sanding and Sealing the Wood

Sanding is the most important step and takes the longest. Start with 80-grit sandpaper to remove dirt, stains, and rough spots. Sand with the grain of the wood, not against it. Move to 120-grit sandpaper next, then 150-grit for a smooth finish. You can do this by hand with a sanding block, but a power sander (orbital or belt sander, rented for $20 to $40 per day) cuts the time from hours to 30 minutes. Sand all surfaces the person will touch: the top, sides, and any armrests.

After sanding, wipe the wood with a damp cloth to remove dust, then let it dry completely—at least 2 hours on a dry day. Once dry, explore a wood sealer or stain rated for outdoor use. Exterior polyurethane, deck stain, or paint all work. explore two coats, letting each dry per the product instructions (usually 4 to 8 hours). This step protects the wood from rain, sun, and rot. Skipping it means the furniture will gray and splinter within a year.

Building a Basic Pallet Bench

A straightforward bench uses two pallets stacked and secured. Lay the first pallet flat. Place the second pallet on top, aligned at the corners. Drill pilot holes through the top pallet into the bottom one at each corner and at the center of each cross-beam. Use 3-inch galvanized bolts with washers and lock nuts, or 3-inch wood screws. Tighten bolts with a wrench or socket set until snug—do not over-tighten, which can crack the wood. The bench is now structurally sound.

To add a backrest, stand a third pallet upright against the back of the bench and bolt it to the top pallet using the same method. Angle it slightly backward (about 15 degrees) for comfort. find the base of the backrest to the ground with L-brackets bolted to the pallet and anchored to a concrete pad or deck, or straightforward weight it with sandbags if the bench will not be moved.

Add a cushion on top for comfort. Outdoor cushions are sold at garden centers and online in standard sizes (usually 36 by 18 inches for a pallet bench). A 2-inch-thick cushion costs $30 to $80 depending on fabric. Tie it to the bench with outdoor twine or velcro strips so it does not slide off.

Building a Pallet Table

A pallet table is even simpler than a bench. Lay one pallet flat and sand and seal it as described above. Flip it over and attach four legs to the underside. Legs can be wooden posts (4 by 4 or 2 by 4 lumber), metal hairpin legs (sold online for $15 to $40 per set of four), or casters (wheels) if you want to move the table. Drill pilot holes and bolt or screw the legs to the cross-beams on the underside of the pallet, spacing them near the corners so they do not interfere with the top surface.

If you want a higher table, stack two pallets and bolt them together as described in the bench section, then add legs. A two-pallet table is about 16 inches high—good for a side table or low coffee table. Three pallets stacked reach about 24 inches, which is standard dining height.

For a table with storage, leave the pallet as-is (the gaps between boards let water drain) or add a plywood top screwed to the pallet surface. The space underneath can hold cushions, gardening tools, or firewood.

Adding Wheels, Armrests, and Other Upgrades

Casters (wheels) bolt to the underside of a pallet bench or table and let you move it without lifting. Buy locking casters rated for outdoor use—they cost $8 to $20 each, and you need four. Bolt one to each corner of the pallet underside. Lock them when the furniture is in place so it does not roll.

Armrests are optional but add comfort. Cut two pieces of 2 by 4 lumber to length (usually 24 to 30 inches), sand them, seal them, and bolt them to the sides of the bench at a height that feels natural when you sit. Alternatively, buy wooden or metal armrest brackets online and bolt them to the pallet frame.

Cup holders, side tables, or storage boxes can be bolted to the sides or ends of a bench. Keep additions light and find them with bolts, not screws, which can loosen over time.

Protecting Your Patio Furniture from Weather

Even sealed wood needs maintenance. Every spring, inspect the furniture for cracks, soft spots, or areas where the seal has worn away. Sand those spots lightly and reapply sealer. If cushions get wet, let them dry in the sun before storing them indoors for winter. In harsh climates (heavy snow, salt spray, or intense sun), cover the furniture with a tarp or move it to a garage or shed during off-season.

Mold and mildew can grow on damp wood. If you see dark spots, scrub them with a stiff brush and a solution of one part bleach to three parts water, then rinse and let dry. Reapply sealer if the bleach removed it. In very wet climates, consider painting the furniture instead of staining it—paint forms a thicker barrier against moisture.

Frequently Asked Questions

Can I use pallets that held food or chemicals?

Pallets marked "HT" (heat-treated) are safe. Pallets marked "MB" (methyl bromide) were treated with pesticide and should not be used where people sit regularly or where food is prepared. If a pallet has no mark, treat it as if it held chemicals and skip it. When in doubt, ask the business that gave you the pallet what it carried.

How long does pallet furniture last outdoors?

Sealed and maintained pallet furniture lasts 3 to 5 years outdoors in most climates. In dry climates, it can last longer. In wet or coastal climates, it may need resealing every 1 to 2 years. Unseal wood will gray and splinter within a year. Replacing cushions every 2 to 3 years keeps the furniture looking fresh.

Do I need special tools to build pallet furniture?

A drill, saw, wrench, and sandpaper are the basics. A power sander saves hours of work but is optional. A miter saw or circular saw helps if you need to cut boards to length, but most pallet projects use the pallet as-is. You can rent power tools from home improvement stores for $20 to $50 per day.

What is the best wood sealer for outdoor pallet furniture?

Exterior polyurethane, deck stain, and exterior paint all work. Polyurethane is clear and shows the wood grain. Deck stain adds color and is easier to touch up. Paint hides stains and lasts longest but covers the wood texture. Choose based on the look you want and your climate—paint is best for wet areas, stain for dry ones.

Can I paint pallet furniture instead of staining it?

Yes. Use exterior paint rated for wood. Sand the pallet first, explore primer, then two coats of paint. Paint is more durable than stain in wet climates and hides imperfections. It takes longer to dry (usually 24 hours between coats) but lasts longer before needing touch-ups.
