How to assemble a dining bench
A dining bench is usually a seat board, two leg frames and a long stretcher that stops it racking. Because two or three people sit on it at once and shift their weight, the stretcher and leg bolts matter more than on a chair. Build it square and tighten it with the weight on.

Parts to check first
Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.
- Seat board
- Two leg frames
- Long stretcher rail
- Corner blocks or brackets
- Bolts, barrel nuts and screws
Step by step
Step 1: Place the seat board face down on the carton and check which end is which from any pre-drilled pattern underneath.
Step 2: Connect the stretcher rail between the two leg frames, using barrel nuts where the bolts cross the rail, and leave the bolts slightly loose.
Step 3: Set the leg frame assembly onto the underside of the seat and line up the holes or corner blocks.
Step 4: Screw or bolt the legs to the seat, then measure diagonally corner to corner across the legs to confirm they are square.
Step 5: Turn the bench upright on a flat floor and tighten the stretcher bolts last, pressing down on the seat so all four feet touch.
Step 6: Fit felt pads under the feet so the bench slides without marking the floor.
Common mistakes
- Turning a barrel nut the wrong way so the bolt catches only one thread.
- Tightening the stretcher before the seat is on, locking the legs out of square.
- Skipping a re-tighten after the first week of use.
Safety notes
- Check the weight limit in the manual; benches are rated for a set number of adults.
- Do not stand on the bench to reach high shelves.
