Description
A single bench seatA seat that is lacking a divider. A long seat for two or more persons that can be changed into a picnic table with ease.
This ‘Bench come Picnic Table’ is ideal for those smaller areas where you don’t want a picnic table taking up all the space, all the time.
When the eating is over and the table is no longer needed, it can be folded back into a comfortable single bench seat and put to one side, still very much usable but taking up minimum room.
It can be either a 2 1/2 seater bench seat (2 adult and a kid), or a 5 seater picnic table.
The front seat spans 1373 mm (54″), the rear seat spans 1245 mm (49″), and the tabletop spans 1487 mm (58½”)

Sourcing the stock sizes
This project calls for two stock sizes – 90 mm x 45 mm (1½” x 3½”), and 90 mm x 32 mm (1¼” x 3½”).
Both stock sizes are available in Australasia. In North America 90 mm x 45 mm (1½” x 3½”) stock is widely available and 90 mm x 32 mm (1¼” x 3½”) stock can be ripped out of 5/4 in. x 6 in. deckA flat floored roofless area adjoining a house. Timber deck: An outside floor structure comprising of posts, bearers, joists and decking boards. boards found at both Lowes and the Home Depot.
Ideally, if you can source or obtain both stock sizes all the better, but if you can only source the 90 mm x 45 mm (1½” x 3½”) stock which is more widely available, then some changes to the plans would need to be made.
