I found Katie Thompson's suitcase chair on stumbleupon and HAD to have it. Being broke and nowhere near South Africa, I made a comprimise.
Her Website is here (http://www.recreate.za.net/about) so you can see more of what she's done. Its amazing!
**power tools are required so please be careful! Ask someone experienced for help. (Thats what I did!)
Added newer pictures, love these chairs!!
Between the two suitcases, we bought 4 (2 by 4's)planks. I advise measuring out the perimeter of the top and bottom before buying.
We assembled the frame outside of the suitcase using wood screws and wood glue. We gave the bottom an extra plank for support.
the frame should fit snug into the suitcase.
Sorry I skipped a couple steps in pictures. :(
FRONT LEGS: We used fence posts! they already have screws in them so all you have to do is drill a hole and hand screw it in. the legs should be attatched through the suitcase and into the 2x4's in the base.
BACK LEGS: We used 2x12 boards to support both the back and the bottom and we could make cool designs with it. I would sugguest reinforcing it with metal braces between the back leg and the suitcase as well. Remember to drill into the frame. If it feels woobly then put in another pair of screws. Better safe than sorry.
So i didn't know this when i began, but furniture foam is REALLLY expensive.
Unless you want to pay top dollar for it, pillows will do just fine.
We used walmart pillows because they just so happened to be the same dimensions. Two for the bottom one for the back.
The fabric NEEDS to be furniture fabric or outdoor fabric otherwise it wont keep up as nice. It took a little bit less than a yard for this one.
Pull the fabric as TIGHT as you possibly can around the pillow and staple it on the underside of the plywood.
