To build my Stairs, I needed hardwood wedges. To build the jig to cut the wedges, I needed Hardwood (oak) strips and chunks. To make the bullnoses, I need hardwood, for the Upstairs (16 treads) and the downstairs (13 treads), and all the tablesaw and drillpress jigs, etc.
SOOO!!! I said to myself, SELF, "Hook up the trailer, and seek out pre-moving day couches!" My buddy and I went up and down 6 backalleys, running 6 blocks each, and found 20 old couches. My little trailer can safely hold 4 at a time. We got picky, and only took the late 60's models and anything close to 8 feet long!
I got solid Walnut show-wood 4/4 X 8', Maple frame wood (Number 2 grade) 5/4 X 8', 6' and 3', Oak, Mahogany frame wood, and more T-nuts than a DIY router table!
Since they've been outside for a few days, in freezing weather, the moisture content was way above furniture grade, SOOO, I laid the wood in front of my shop's baseboard heater covered with a tarp (Canvas) and got it dried out to just under 10%.
Its a PITA to pull all the staples and stuff, but when I saw that the local Home Despot priced for a 3/4" X 3" X 8' S4S chunk of plain old Fir, I didn't even look at the Oak!
Anyway, this stuff is great for small bits and pieces in the shop. I figure I can build a small Solar Kiln in the backyard (south-facing) for summer use, for under $200, and do a Month End Couch-Run, when the weather comes back up to Humane Levels in May (up here we still have Snow sometimes until early June).
Found a good website to build solar kilns too: Solar Wood Drying
The one I like best is about 2/3rds down, with this text below. Its a free PDF, with all the moisture content ratings for the major woodworking species in the document, as well as the plans and details (materials list).

EDIT: I used to restore upholstered furniture after highschool, to make some money for my hot-rodding hobby, back in the 60's. There's some really slick staple-pulling tools in that trade that you can usually find at the upholstery shop fabric vendors. It's still a PITA, but not as bad as a sharp screw driver. Just watch out for the springs. They can spring back at you and knock a finger off or worse! The cheaper couches didn't use burlap between the springs and the liners, Burlap is a good fabric for all kinds of uses, including cleaning whitewall tires, but it really shines where you need to keep metal away from wood or other textiles, including separating wood for air-drying.
