For those of us, who like to have a guest bed without devoting an entire guest bedroom
Step 1: Planning
Its always important to plan out your project so you know what to buy and how to build it.
For this project, i wanted a fold-up easily movable guest bed. I already had an exta full-size mattress so thats the size i shot for.
* Please dont use these exact measurements for your own project. I live in Japan and things are slightly 'metric' here
My parts List:
6x slotted angle Iron (300cm long each)
How to cut the iron (to prevent waste and save $$$)
6x locking wheels
4x hinge bolts
4x trailer pins
22x corner braces
100x 6mm round-head square shank bolts
4x 6mm wing nuts
2x foam corner protectors
2x 6mm wing nuts
10x Wood slats cut at 140 cm
2x door hinges
2x 30cm long wood supports
Step 2: Frame Assembly
If you have access to an impact drill, it will make this much easier for you...
Assemble the frame, with the rounded head on the side where the mattress will be, you do not want to damage you mattress unnecessarily.
The corner braces are an optional accessory that make a suprising difference in stability. I suggest, if you have access to them, to purchase and utilize them.
Step 3: Legs/base
After assembling the legs, and base, and adding the wheels to it, you are ready for wood slats
Step 4: Wood Slats
It its important to add wood slats, so the angle iron doesn't decide to bow outwards and allow the mattress to fall through. Here i used 10 slats. 1 on each end and 8 evenly spaced in the middle of the frame.
Step 5: Final Touches
I used two bargain straps i got at the local hardware store to hold the bed against the frame for vertical storage, as well as two hinges to add legs to support the slats from bowing to far from the weight of a body.
I also used 4 corner braces as trailer pin inserts for holding the legs in the up/down positions, and the the frame in the up/down positions
The wing nuts, allow the user to tighten/loosen the 'hinge' before or after moving the bed up/down.
