Wedding Benches

Screw the 2x4 top boards to the 2x6 support boards, spacing screws every 8"–12" along the length.

Screw the end boards to both ends of the 2x4-and-2x6 assembly.

Screw the legs to the inside of the outer frame. Angle a few screws in on each leg rather than driving them all straight — this resists the leg racking sideways under load.

Add a tie-in board between the two legs near the bottom, leaving about a 3" gap below it. This is what keeps the bench from wobbling once it's loaded with people sitting and standing — don't skip it.
