My chair broke. The backrest came off. I squirm around a lot (I'm a restless person) and the metal had gotten tired and given up. Fortunately we had a replacement to hand- an office chair we bought a while back for Ailz but which she couldn't use because the wheels were too slippy, weren't slippy enough (I forget which). It was standing around in her room, pretending to be a table. I'd written it off as a bad buy, but it's turned out to be an investment. It's also very comfortable. I wonder how long it will take for me to kill it?
