1 Measure and cut the following lengths of 1in x 1in (34mm x 34mm) wood: 2 pieces 33.5in (847mm) long, 2 pieces 18in (460mm) long, 2 pieces 18.5in (470mm) long, 2 pieces 18in (454mm) long, 2 pieces 21in (538mm) long, 4 pieces 15in (380mm) long, 1 pieces 13.5in (340mm) long, 1 pieces 17.5in (440mm) long, 1 pieces 14in (350mm) long.
2 Lay a 33.5in (847mm) long piece vertically. Horizontally, position one 18.5in (470mm) long piece 17.5in (440mm) from the bottom of the 33.5in (847mm) long piece. Then horizontally position one 18in (454mm) long piece 4in (104mm) from the bottom of the 33.5in (847mm) long piece.
3 Drill and countersink one hole where each horizontal piece overlaps with the vertical piece.
4 Twist a screw into the holes to join the two horizontal pieces to the vertical one.
5 Position one 18in (460mm) long piece under both horizontal pieces. Use the end of a spare piece as a spacer, and drill + screw the 18in (460mm) long piece to the 18.5in (470mm) long piece. Make right angles between all 4 overlapping pieces, and add one more screw to complete the square. Place and screw a 21in (538mm) long diagonal piece for stability.
6 Repeat a similar process as in steps 2-5, making a structure almost mirroring the one made in steps 2-5 (the diagonal piece placement is not mirrored).
7 Leaving 1 width of wood space on either side of the frame, position a 15in (380mm) long piece 4.5in (116mm) from the top of the frame. Secure in place by drilling two holes and adding two screws.
8 Place another 15in (380mm) long piece across both 18.5in (470mm) long pieces, and against the 33.5in (847mm) long pieces, flush with either side of the frame. Secure in place by drilling two holes and adding two screws.
9 Place another 15in (380mm) long piece across both 18.5in (470mm) long pieces, and at the very front of the frame, flush with either side of the frame. Secure in place by drilling two holes and adding two screws.
10 Place another 15in (380mm) long piece across both 18in (454mm) long pieces, and 3in (80mm) from the front of the frame, flush with either side of the frame. Secure in place by drilling two holes and adding two screws.
11 Place the 13.5in (340mm) long piece across both 33.5in (847mm) long pieces and 4in (104mm) from the bottom of the frame, flush with either side of the frame. Secure in place by drilling two holes and adding two screws.
12 Place the 17.5in (440mm) long piece diagonally across both 33.5in (847mm) long pieces. Make sure the frame is straight on a flat surface. Secure in place by drilling two holes and adding two screws.
13 Place the 14in (350mm) long piece diagonally across both 18in (460mm) long pieces. Secure in place by drilling two holes and adding two screws.
14 Measure and cut the following rectangles of 1/2in (12mm) thick plywood: 1 piece 18in x 15in (450mm x 380mm), 1 piece 10in x 15in (250mm x 380mm). Have these pre-cut at the store, if possible.
15 Place the 18in x 15in (450mm x 380mm) piece on the seat area and drill + screw it into place with 4 screws.
16 Place the 10in x 15in (250mm x 380mm) piece on the back rest area and drill + screw it into place on the 33.5in (847mm) long pieces with 2 screws.
17 Not part of the original design: If you are using softwood that is relatively thin, you may need to reinforce the back area, so it doesn’t break under pressure. To avoid this, use softwood that is at least (34mm x 34mm), or use hardwood (like maple).
18 To make the seat have a nice angle, cut 3/4in (17mm) from the bottom of the back legs. Then fold a blanket to about 44in x 16in (1100mm x 400mm) and place it on the chair.
19 Wrap one side of your Hook and Loop (or Velcro), with the flat side exposed, around the top of the back rest twice.
20 Pull tight, and insert a small piece of the opposite side of the Hook and Loop (or Velcro) underneath to secure.
21 Repeat steps 19-20 to secure the rest of the blanket to the seat and the back rest.
