I have two ancient armchairs which really ought to go but which I would like to keep for sentimental reasons. But their springy bits have gone unspringy, and something somewhere goes Boiiiing every now and then. Does anyone know where to find out about getting them perked up, or better still doing it myself? I've not had much luck on google, probably because I don't know what I'm talking about and keep searching for the wrong thing.
thanks
