JRC clubman bedchair

I have recently just bought a new JRC clubman 2 legged bedchair for ?49.99, i thought this was a bargin at the time only 2 later realise that it is only rated 2 twelve stone!!!! i weigh in at 11st 10lb, and was wondering how true to the fact is the actual stone rating?? i.e (when will it start to fail)
any help on this matter would be greatly apreciated

Dont go to one of Wols bbq's or you might find out!
Where did you find the ratings?

I had a jrc clubman for 18 months, but it was the 3 legged version which was rated at 18 stone I think. At the time I was weighing in at about 19 and a half stone and it was fine.

I'm not fat or anything just very tall
