Chair repairer

[minimoonumbertwo]

Wonder if anyone can help...my dh broke our lovely arm chair with his big bottom last night - it's a kind of sixties low one with a metal frame and one of the elasticated bits at the bottom has popped out. It looks as though it will be easy to fix with the right tool, just needs to be popped back in again. Does anyone know of any good furniture repairers in or around London? Thank you
