Inspired by the many 'nomad furniture' designs out there I have made a very simple stool out of cardboard. They are super easy and cheap to build.
And, having some cardboard handy (for emergency projects!) is useful.
Step 1: Materials
Lots of clean cardboard (no cockroaches!)
Step 2: Measure Desired Height
If you have children in the house, you may want shorter stools. I took an existing stool and marked the height directly to the cardboard.
Use a pen/pencil, whatever, to mark and then cut the cardboard.
Step 3: Roll Your Sheets of Cardboard
Once you have a few sheets, go ahead and roll them.
Step 4: Too High? Measure Again and Use Saw
I made a stool for a taller person but found it wasn't being used as much so I measured again and cut it down to a more comfortable height with a wood saw.
Step 5: Roll the Sheets As Tight As You Can and Wrap
You'll want to try and wrap the cardboard as tight as you can or as my grandfather says you'll get too much air conditioning! But, don't worry too much about the gaps in the cardboard. Wrap with a wire or string but I like to use bungie cords(elastic strap with hooks) as I can add or remove more cardboard as needs be.
You can throw paint or color it or put a cushion on top. It's cardboard after all.
Now, give it a sit!
