DIY Patio Couch Build | Modern Outdoor Sofa & Slatted Frame | #52

We wanted a nice L-shaped sectional for our patio. We looked at West Elm. $2,500. We looked at Wayfair. $1,200 (for flimsy metal).

I said, "I can build that."

Design Strategy

The expensive couches use Teak. I used Douglas Fir 2x4s. If you sand and stain cheap construction lumber properly, it looks like custom furniture.

Key dimensions: The couch size was dictated by the Cushions.
Pro Tip: Buy the cushions first. Building a custom frame to fit standard IKEA cushions ($50 each) is easy. Building custom cushions to fit a weird frame costs $500 in foam and sewing.

Contrast Design

Reference my Garden Bench project: I like the mix of wood and black. I decided to stain the frame a dark "Espresso" color, but use Cream White cushions. The contrast is sharp and modern.

The Build Process

Step 1: The Base Platform

I built two sturdy rectangles out of 2x6s.

Legs: I used 4x4 posts for chunky, solid legs.

Step 2: The Slat Back

I didn't want a solid plywood back (it looks cheap). I ripped 2x4s into 1.5" square strips and spaced them out vertically. It gives it an airy, mid-century vibe.
