6mm spacers

3 packs of 8mm x 30mm chipboard screws

1 pack 6mm x 40mm chipboard screws

Wood glue

Wood filler

120-grit sandpaper

Paint or varnish to finish


Drill /Driver plus assorted bits


Corner square

Tape measure and pencil








1. Make the seat by placing the [4] 22 x 69 x 1500mm and the [4] 22 x 44 x 1500mm planks next to each other, alternately.

GOOD TO KNOW: Use a wood clamp to hold the planks in place and the 6mm spacers to make sure the gaps are even.

2. Place the [4] 22 x 69 x 475mm supports at right angles across the seat planks and space them as indicated on the sketch (opposite). Using 8mm x 30mm screws, glue and screw the supports in place in a zigzag pattern.

Make the backrest, sides and front by repeating the above process (see sketches). 



3. Join the seat to the backrest with the 6mm x 40mm screws. Attach the 1500mm support for the seat and backrest to the backrest supports/legs to reinforce the seat. Screw the front panel beneath the seat.



4. Attach the inner panel for the sides to the backrest and seat. Attach two of the 22 x 94 x 745mm planks to the front of each side to finish off the front of the armrest. Screw two pieces of offcut wood to the bottom of the front supports to reinforce the front of the armrest with the front panel. Glue and screw the 22 x 94 x 1500mm plank to the top of the backrest.



5. Place the outer panel of each side in position and attach with the 6mm x 40mm screws. Complete the armrests by screwing the 22 x 94 x 570mm planks on top.

6. Turn the bench over with the backrest facing upwards and screw the 22 x 94 x 1600mm plank to the bottom of the legs to reinforce the sides. Screw the remaining 22 x 94 x 745mm planks to the back of the armrests to complete the bench.




Fill all visible screw holes with wood filler and allow to dry completely. Sand the bench thoroughly and paint or varnish in the colour of your choice; we left the wood untreated.
