Building a DIY wooden slatted chaise lounge is the perfect weekend project to create a stylish and comfortable spot for relaxing in your garden or on your patio. This classic design, with its sleek, curved lines and ergonomic slatted surface, offers exceptional comfort and a modern look. By using marine-grade plywood for the sides and solid spruce lamella for the slats, you’ll ensure your chaise lounge withstands the elements for years to come. Below, we walk you through the key steps to craft this beautiful piece of outdoor patio furniture.
Design and Planning Your DIY Chaise Lounge

Before cutting any wood, it’s essential to study the design. The chaise lounge features two long side pieces that curve downward at the front and middle to form legs, while the back section rises at a gentle angle. The slats follow the top contour of these sides, creating a single, ergonomic surface from head to toe. The position and shape of the rear legs are critical to prevent the lounge from tipping backward when you sit up. For inspiration, browse outdoor patio furniture designs or even garden supplies to see similar styles.
Materials You’ll Need
- Marine-grade plywood panels for the side frames
- Spruce lamella (or similar hardwood) for the slats – choose a thickness that offers durability
- Stainless steel or coated screws for outdoor use
- Wood preservative or outdoor sealant (three coats recommended)
- Cardboard for creating a template
Step 1: Create a Cardboard Template for the Sides
Start by drawing the side profile on a large piece of cardboard. This template is crucial for achieving the perfect curves and ensuring both sides are identical. Test the template by sitting on it to check comfort and balance. Once satisfied, trace the shape onto your marine-grade plywood.

Step 2: Cut and Shape the Side Panels
Using a jigsaw, carefully cut along the traced lines. Sand the edges smooth to prevent splinters. The front and middle sections should curve downward to form stable legs, while the back section rises gently. If you’re working on a work surface like a sturdy bench, it will make the cutting process much easier.
Step 3: Attach the Slats with Even Spacing
Lay the side panels flat and mark equidistant points for the slats. Pre-drill holes in the sides and then attach each slat using countersunk screws, driving them flush with the wood surface. The slats should overlap the sides slightly for a clean look. For a comfortable lounge, space the slats about 1–2 cm apart. Consider adding a outdoor decor cushion or two for extra luxury.
Step 4: Apply a Protective Finish
Because this chaise lounge will live outdoors, apply at least three coats of a high-quality wood preservative or outdoor sealant. This protects against moisture, UV rays, and mildew. Let each coat dry thoroughly before sanding lightly between coats. While waiting, you might also want to explore outdoor lighting to create a cozy evening ambiance around your new lounge.
