What you’ll build
Each trestle is two 2x4 legs crossed in an X with 30° end cuts, capped by a 17″ 2x4 cleat. Two 27″ 2x4 stretchers link the three trestles, and three 84″ 1x6 planks make the seat.

Step-by-step instructions
Assemble Left Trestle Leg
Cross the left front-leaning and rear-leaning 2x4 legs flat on your work surface so their faces lap together and the top cut ends align evenly. Position the 17-inch left top cleat across the top ends, flush with both outer edges, and clamp the assembly flat.

Assemble Center Trestle Leg
Lap the center front-leaning leg over the center rear-leaning leg on a flat work surface with the top cut ends aligned. Set the 17-inch center top cleat across the top of the crossed legs, keeping the outer edges flush, and clamp the pieces firmly.
