Cardboard Chair DIY

Chair made of recyclable cardboard that isn't connected with glue or other materials.

• Double walled cardboard (this is two layers on top of each other this is stronger than single walled) 8 times 720x 690 mm, 14 times 451 X120 mm,1 time 510X 70 mm
• Measuring tape
• Sharp knife
• Scissors
• A3 Papers (or 2xA4)
• Pencil
• Tape 

Collect cardboard; this will require large boxes, such as those from new appliances or furniture; if you don't have any old boxes, ask friends or businesses that sell these items. (I used banana cartons and boxes made for folding chairs) For the horizontal panels, you need eight flat pieces that are 720 x 690 mm in size. For the horizontal panels It is necessary to cut out at least 14 pieces of cardboard measuring 451 x 120 mm and one piece measuring 510 x 70 mm.

Templet may be printed or drawn.

Print

Use the templet (cardboard chair horizontal plates) to print this, if you can draw it (thickness of the groves should be adapted to the thickness of the vertical panels that slide into these groves see the technical drawing.)

Draw

Make a drawing of the seat and backrest's horizontal panels using the dimensions shown in the image (the thickness of 7mm of the groves depends on the thickness of the cardboard, first measure the cardboard of the vertical panels that slide into these groves, and use this thickness.) Cut the drawing out, and use this to trace over the cardboard. 

Use the paper templet of the chair to trace over the cardboard with a pencil and cut it out. It will be easier to cut the cardboard if you first cut the groves with a knife. The outline can then be carved out after that. Repeat this process 13 times to create all 14 horizontal panels.

Draw out the first seating panel, this one is smaller than the other horizontal panels this one is 70 mm instead of 120 and the grove is 30 instead of 60. You do not need to draw a new template. Use the other templet and a ruler to draw this on the cardboard; the red lines in the second drawing show where the lines should be drawn. After that, you can cut one panel out. 

Templet may be printed or drawn.

Print

Use the templet (cardboard vertical horizontal panels) to print this, if you can draw it (thickness of the groves should be adapted to the thickness of the horizontal panels that slide into these groves see the technical drawing.)

Draw

You can make the templet as well with A3 papers. Tape the papers together to create at least a big piece of paper with the sizes 720x 690 mm

Draw out the straight vertical panel, and use the measurements of the picture (the thickness of the groves depends on the thickness of the cardboard, first measure the cardboard of the horizontal panels that slide into these groves, and use this thickness.) Cut the drawing out, and use this to trace over the cardboard.

Use the paper templet of the chair to trace over the cardboard with a pencil and cut it out. It will be easier to cut the cardboard if you first cut the groves with a knife. The outline can then be carved out after that. Repeat this process 7 times to create all 8 vertical panels.

Assemble the chair. Start with the outer two vertical panels. Then you can add 4 horizontal panels. After this add the other 6 vertical panels. Last but not least, insert the horizontal panels, then take a seat!
