I also wanted to build the bed out of scraps and found materials - along with some supplies I had lying around - i.e. I didn't want to have to buy anything to make it. Now, I realize that very few people are going to have most of these supplies "lying around" (what can I say? I'm a pack-rat) - but they would be readily available from most upholstery supply shops. I buy a lot of my supplies from here: http://www.rochfordsupply.com as well as from local suppliers.
Total cost, if you were to buy everything, would probably be around $100 - which is half what I've spent in the past on beds that didn't last much more than a couple of years. In addition, this bed can be easily cleaned (most can't) - and if the need should arise it can be recovered for about what a cheap dog bed would cost.
- 1000-Denier, urethane-backed Cordura - I picked up some on clearance a few years ago (hence the cammo pattern). It's waterproof, abrasive resistant, and tough - and was pretty inexpensive.
- 1/2" Dacron batting
- Scrap 2"x4" lumber for the frame
- Scrap 1/2" or 3/4" plywood for the bolsters
- Elasbelt Webbing - like very strong elastic - used as a replacement for springs in furniture
- Urethane Foam - good furniture-grade foam will last a lot longer and be more comfortable
- 1" Hook and Loop fastener - about 6 feet should do it
- Staples, Foam Adhesive, Screws
Step 1: Build the Frame
This frame is assembled entirely with screws - no glue. If you have a pocket-hole jig, this would be a great use for that as well.
The goal here was a strong, square frame that could handle the continuous tension of the webbing as well as the weight of Mac.
Be sure to drill pilot holes for your screws - Why? Because pine is notoriously easy to split. The only time I don't drill pilot holes is if I'm using a self-drilling screw like a "Spax" brand screw - which I used to install the corner braces.
As for the rest of the description, I'll let the pictures do the talking.....
