Step 1:

Materials:
I used a Cardboard with density ≈ 300 g / m²
1- 4 pieces of Cardboard with size: 150 cm x 15 cm each (Rails).
2- 8 pieces of Cardboard with size: 37.5 cm x 24 cm each (Rungs).
3- 4 pieces of Cardboard with size: 20 cm x 15 cm each (Footpads).
4- 2 pieces of Cardboard with size:   7 cm x 8 cm each (Hinges).
5- 4 pieces of Cardboard with size: 6 cm x 15 cm (Top pads).
6- 16 pieces of Cardboard rolled with 7 cm long and 8 mm Ø diameter (Pins).

Although this ladder is made of thick paper but still can change to a real working ladder by using proper materials and necessary modifications to ease closing and secure against slipping and collapsing,

I think when u climb it will break

The Folding Concept is Great ! Thanks for sharing.

I recall a commercial about 15 years ago that showed a full sized car driving over a corregated boxware arch. It had no struts under it. I used to make the stuff in Seattle, resisting compression downward on the flutes "center layer" was very strong. If You are well balanced You can stand on a corrigated box sitting flat on the floor. It all depends on flute size and paper weight of manafacture. Those made to ship heavyer items are supriseing. Walk gingerly on the rice paper Grasshopper. HAR.!

What weight can this support?

[dvdspeler]

a.k.a. where are the pictures of you standing on it? =P

I think I might make one of these, except use aluminum channel for the sides and aluminum tubing for the steps.

[saidseyam]

Good idea, aluminum channel thickness should be 3 mm or more, good luck and let us see photos.

This is a great idea! I'd love to see someone expand on it with materials that could be more weight-bearing. Great way to think outside the box. You, and people who design these types of things, just amaze me the way your minds work.

This is a fascinating design - it folds wonderfully, and does look as though it is theoretically sound. The material you have used, however, appears too light to hold a person's weight. I wonder if this is a working model? I am very curious to try building these components using at least two layers of corrugated cardboard with a "skin" made of the sort of material you have used here, to strengthen it.
Very clever! Thank you for showing this. :D

It certainly looks like a ladder. Do you have a photo of someone standing on it? What stops the legs sliding apart? And if you tread on the treads, what stops them breaking?

This seems more a "proof of concept" than a working ladder. Though I have seen the same design in a wooden ladder that worked. Lots of hinges.
