After I finished the instructable for a dollhouse I made for my daughter, I wanted to make something new. Practically enough, her birthday was coming up and she also was going to need a bigger bed. Combine those two things, with the fact that my wife and I are interested in montessori education and the parenting style that comes with it, a floor bed was the logical result. We decided to use a mattress that was 80 cm wide and 160 cm long
Important: After I build the bed, I found out that a mattress of 70 cm wide and 140 cm long would have been way easier. That is a standard size and is also cheaper when you order it online.
Of course we could just lay the mattress on the floor, but that is just too easy. I wanted to create a very simple (read: cheap) frame that would just interlock using cutouts (edge cross lap joints, to be precise). Turns out my wife had a different idea in mind. She had the wonderful idea to turn the bed in a reading nook. That meant, a small bookcase or shelf needed to be added! Alright, no problem I redid the drawings and made some new calculations. Then a colleague came up with the idea of a secret compartment under the bookcase. By adding hinges of some sort to the bottom that was relatively easy and pretty awesome, so I took that into account too.
Like I said, we went for a mattress that was 80 cm wide and 160 cm long, the bookcase needed to be at least 28 cm deep and 30 cm heigh to make room for even the biggest books. The extra shelf on the headboard did not need to be of a specific depth, as long as it could hold a glass of water it would be alright.
All in all I have spent a bit und 50 EUR on all the wood (that is a bit more than 56 USD). I bought 18 mm spruce furniture boards and I had them directly cut to size at the hardware store (they do that for free). Screws were "for free", because I collect them whenever I can and also the dowels and centering spikes were already in my possession from another project (although I needed to buy another pack of dowels, because I ran out). One tool I used, I borrowed from a friend. It is a guide to drill the holes, don't what to call it exactly, but it made drilling straight, in the right spot and a lot easier!
Of course if you want to recreate this Instructable, you can adjust all the measurements, forget about the book case or or the shelf or just make it completely different! I would propose you use wood you have already lying around, if you have any.
Tools that where used in the process are:
Then some hardware was be used to put it all together:
As far as material goes, this is what went in to the bed:
The idea of making the bottom of the bookcase into a secret compartment was easily solved. I glued two dowels into the board, left and right, and made the corresponding holes in the sides a bit too big, so they could freely rotate.
