How the design works
A low lounge with posts at the corners, rails, a slatted seat and back, and arms. Cushions sit on the slats.
Starts at about 1.8 m long with a 380 mm seat (72 in long in US sizes). Change any size and everything else follows.
What Woodworker checks
- Seat and back slats bending
- The back frame when people lean back
- Wobble of the whole frame
- Whether the wood lasts outdoors
When something isn’t strong or stable enough, it says why and offers a fix you can apply in one click, like a bigger section, an extra brace or a different joint.
What you can change
- Length, depth, seat height, back height and arm height
- Slat, post and rail sizes
- Weight of each person (Advanced)
What you get
- A cut list of every part, with sizes, wood and how many
- A shopping list of timber lengths or sheets, screws, bolts and hardware, with rough costs
- Assembly steps in build order, with the joints and fixings for each step
- Dimensioned front, side and top drawings, and a printable workshop sheet (PDF)
Tips
- Measure your cushions first and size the seat to them.
- A slightly lower, deeper seat is more relaxed than a dining bench.
Questions
- Can I make a corner sofa?
- Design two sofas and put them together in the Garden Planner, or use Build your own to join the parts.
- Is it really free?
- Yes. Woodworker is free, with no ads and no account. Designs are saved in your browser and never uploaded.
- How accurate are the checks?
- They use Eurocode 5 methods and common furniture test loads, as a guide for home-made projects, not certified engineering. Ask an engineer about anything large or anything people could be hurt by if it failed.
