Not being a fan of mass produced Ikea furniture boringness, I decided I was going to make myself a bed frame. And if I'm going to design and make something myself, I'll do my best to make it something unique and interesting!
I set out to design a bed frame that gave the illusion it was floating, to do away with the usually leg in each corner and try hide the base structure as best I could when viewed standing up...
After multiple suggestions to, I added some LED strips lights around the parameter of the underneath.. really adds to the affect! Cheers to those who commented and made the suggestion!)
And this is what I came up with. Six arms reach out from a central spine to support the bed surround and headboard. These arms are pin jointed at the base, with wire rope tensioned between opposite arms to constrain their width and further rigging down to the base to create a static, level structure. The base extends out to prevent the whole thing tipping over when your sat on one edge with minimal flex.
The bed is designed around a standard 4ft6 mattress. The overall dimensions are 2120mm long and 1570mm wide, the surround sits at a height of 350mm.
The CAD model and drawings I created for this can be downloaded from my website here:
I've also entered this into the Wood Competition, so if you feel its worthy, a vote would be very much appreciated!!
Things you'll need.
Tools I used:
I started with this idea of creating a bed that appeared to float from certain angles. After sometime sketching out different concepts on how this could be achieved, I moved into CAD to detail the design. From this CAD model I then created a series of drawing for each component that I would produce from the scaffolding boards. The dimension of standard scaff boards were kept in mind and used to constrain the dimensions of parts.
The arms are pin jointed rather than fixed to reduce the stresses in that area of the design. Using a pin joint means they are essentially free to rotate and so are free of moment stresses when you load the end of the arms, now the joint mainly has to deal with compression loading. To prevent the arms from rotating, cable is rigged between the opposite arms which goes into tension when the arms are loaded. And with just 4mm cable having a min breaking load of ~1000kg the structure should remain solid. Think of a boom/tower crane - same principles. If fixed at the base the arms would want to bend!
The CAD design is almost the same as what I ended up building but as you can expect there were minor changes that needed to be made along the way.. I've not had time to update the CAD model, but if you choose to use my drawings they'll be a good start.

With the design sorted, it was time to start building! I've given a summary of the steps I took and the photos should help, but essential you just need to create the parts specified in the drawings.
