The only material you need is large pieces of card that are at least two layers thick. The largest piece measures 83 x 60cm so you need to look for large boxes, which are more likely to be found in bins where businesses have large items delivered, such as furniture shops.

There are eleven pieces needed in total and you can see how they need to be measured and cut in these plans.

It has been designed so that it will be big enough for one person but also small enough to be transportable when disassembled.

It is important to get properly strong cardboard as it has been found to weaken due to re-assembly and dis-assembly. The ideal type would be 3-layered card or card that you can tell is much more rigid. The other thing is that it needs to be assembled and disassembled carefully so as not to bend the card.

To do the cutting, all you need is a sharp craft knife, a pair of scissors for back up and a large board to cut on where it doesn't matter if you scratch it (I salvaged one from a discarded kitchen).

The upper section has four pieces, the base has three plus four supports to ensure stability and long life.

Try to find a large plastic bag to put all the pieces in and a long piece of string to wrap it up and create the handle for carrying (see later).

Note the direction of the lines in the card. It is important that you position them this way so that each vertical piece will have all the card lines vertical as well, which is necessary for stability.

There is also the assembly instructions sheet that you can print out to give to the users of the beds.
