2. DIY Pallet Couch Projects
Pallet couches are among the most popular outdoor DIY furniture options because they combine low cost, high style, and endless flexibility. Whether you’re furnishing a sprawling garden patio or a tiny city balcony, pallets can be easily customized to fit your space.
Start by sourcing clean, heat-treated pallets—look for the “HT” stamp to avoid chemicals. You’ll need about 2–3 pallets per seat section: one or two for the base, and one for the backrest. Sand thoroughly to avoid splinters, and consider staining or painting to protect the wood from the elements.
Stack pallets for your desired seat height (standard is 16–18 inches), then screw them together securely. Use angle brackets for attaching backs if you want a more upright design.
Finish the couch with outdoor cushions. For a rustic boho vibe, go for mis-matched textiles; for a polished look, use matching neutral-toned cushions with piping. Don’t forget to place it on a rug or over pea gravel for added coziness.

5. Adding Comfort: Cushions, Fabrics, and Waterproofing
Even the most structurally sound DIY couch won’t be inviting without the right cushions and soft layers. When choosing materials, prioritize comfort, durability, and weather resistance.
Start with high-density foam—2” to 4” thick depending on preference. You can buy pre-cut pieces or custom cut them to fit your couch dimensions. Wrap the foam in waterproof covers or sew your own using outdoor fabric brands like Sunbrella, known for its UV and mildew resistance.
Add a combination of square and lumbar pillows to support the back and encourage lounging. For texture and style, layer with a few patterned throws or a lightweight outdoor blanket.
Make sure to bring cushions inside during extended rain or use storage benches to keep them dry. And for the finishing touch? An outdoor rug and a side table will make your DIY patio couch feel like a true outdoor living room.
