Cardboard Bar Stool

Posted in 04.Cardboard Furniture Presentation on February 10, 2010 by swathibhat

Simple and suave is always the best way to go. We therefore decided to build simplistic yet very sturdy bar stool. The stool is 2 feet tall and is tested with humans weighing up to 175 pounds.

Instructions on making the stool:

Step 1:

Cut and fold 8 circular cardboard made of multiple 11.5″ diameter circles folded over each other to make a strong sitting surface at both ends.

Step 2:

Cut and fold cardboard cut into dimensions 3/8″ cardboard, 23.5″ x 48″, which is the weight-bearing element in the stool. It is just a large sheet that is rolled into a tight cylinder. You can make folding easier and more precise by using a straight edge and a blunt instrument to score parallel lines into one side of the cardboard. The cardboard will then fold nicely along these lines. We used two concentric cylinders instead of one to make it more sturdy.

Step 3:

Glue the two circular discs made in step 1 to both ends of theΒ  cylinder.

We bounded the cylinder with a cardboard ring for more stability.

Step 4:

Cut thin pieces of diamond out of a cardboard of dimensions 3/8″ cardboard, 24″ x 72″ allowing the middle to be pressed in when it is rolled up. The result is an hour glass shape.

Step 5:

Test fit the parts, and then start gluing things together. It will look all the more impressive if none of the glue is visible or duct tape is visible πŸ™‚

Step 6:

Let the glue dry fully before you sit on the stool. If you have built the stool well it will be quite sturdy, but you should sit fairly still. Tilting or leaning will wear it out quickly.
