Step-by-Step Instructions

1

Plan the Curve

Measure fire pit diameter and plan bench segments at least 3 feet from the fire ring.

2

Cut Leg Assemblies

Cut 2x4 legs to 17 inches and crosspieces. Join into H-shaped frames with screws and glue.

3

Set Miter Angles for Curve

Set miter saw to 10-15 degrees. Cut seat board ends at matching angles to form the arc.

4

Attach Seat Boards

Pre-drill and screw 2x6 or 5/4x6 seat boards to leg assemblies. Use two boards per section.

5

Level and Stabilize

Place benches around fire pit and shim legs as needed. Add diagonal bracing if needed.

6

Sand and Finish

Sand all surfaces, round over sharp edges, and apply two coats of exterior stain or sealer.

Recommended Species

Western Red Cedar, Pressure-Treated Pine, Redwood

Recommended Sizes

2x4 legs and framing, 2x6 or 5/4x6 seat boards

Pro Tips

Keep benches at least 3 feet from the fire pit edge. Cedar stays cooler to the touch than treated pine. Build in individual sections so they can be moved for cleaning. Sand all edges thoroughly since bare skin will rest on surfaces.
