This is my wife's badassity, but too badass not to share!
Our main chair-actors:
Chair A: My dad's old chair. An overly expensive fancy-pants chair that was broken on stem from years of having a mobility challenged man drop his full weight into it. Mom couldn't toss it when Dad died because "it cost so much when new." It ended up in our basement storage with vague thoughts of trying to fix it someday.
Chair B: This was brought into the marriage by wife. It's at least 17 years old. The base and stem are built like a tank, but the back and arms had fallen off over the years, resulting in an odd-looking swivel stool.
Chair C: My beloved chair. Black leather and armless, purchased for $5 at Goodwill some years ago. Unfortunately, the plastic cracked and a wheel would randomly fall off when sitting upon the chair. Exciting but not great for work. The padding in the seat was also quite flattened, which could be tough on the derriere.
Were our three heroes destined for dumps-ville, or could a menage et trois save them?
Chair A and Chair B hit it off first. With a deft turn of a few tools, the seat of chair A replaced the worn out seat of Chair B. It was a match made in heaven! Wife's chair has the overly expensive comfy seat of one chair, and the tank-like base of the other.
The wheel part of the base of Chair A was also in good condition, so a few more twists of the wrench and Chair A had a second lover -- Chair C. Now my chair can wheel all over the house if need be.
But! Chair B was jealous of Chair A and Chair C, so decided it needed in on the action. (Did I mention Chair C is a leather wrapped hottie?) Wife stripped the foam padding out of the remaining seat from Chair B, and added it to the broken down padding in Chair C, thus blending all three chairs together into two like-new chairs ready to ride off into the sunset together!
All we are left with now are a few broken parts -- old wheel base, old base stem, and the remains of a seat. We saved the casters and gave the metal bits to a scout scrap metal fundraiser. The rest went out with the normal garbage.
Thus endeth our tale
