To build a cardboard chair, create a base with a single box, and use scrap cardboard to form the rest of the chair. You need one corrugated cardboard box, scrap cardboard, scissors or a box cutter, a pen, a tape measure, a straight edge and wood glue.Continue Reading
If your cardboard box is not put together, use packing tape to secure the bottom, and leave the top flaps open. Use the tape measure to measure the length and width of the bottom of the box. Write the measurements down.
Spread a generous amount of wood glue along the open flaps. Turn each flap over, and secure them against the inner walls of the cardboard box. Allow the glue to dry for a minimum of two hours.
Gather your scrap cardboard. Use the tape measure, straight edge and pen to draw six cut-outs that match the measurement of the bottom of the box. Cut each part out.
Make sure the glue applied earlier is dry. Turn the box over so the bottom is facing up. Spread glue along the bottom, and place one of the cardboard cut-outs on top of it. Repeat with the remaining cut-outs, but leave one leftover.
Spread glue along one edge of the cardboard cut-out. Place the cut-out against the cardboard box, and press down firmly. Wait for the glue to dry for at least two hours before testing the chair.
