Aeray is a professional carpenter, furniture maker, designer and builder and he's frustrated with the overbuilding and over-engineering done on simple DIY projects. His goal for his tutorial on Instructables is to illustrate how to simply and inexpensively build a multipurpose platform deck that can be used for a queen sized bed, a futon mattress, or a waterproofed, cushioned poolside lounger (as suggested by one commenter).
For under $30.00, low-waste, a few tools, and an hour or two, you can build it.
I'd like to shrink this down to bench size, paint it and make a couple of boxed and corded cushions to sit on top; very modern, minimal, and functional.
Here are the tools he used:
Saw (Skil, hand, jig, or miter. Shown is a Skil)
Square (Speed, framing, or try. Shown is a speedsquare)
Drill (Cordless or corded)
Appropriate driver bit for your screws
#10 pilot bit/countersink
