No, the Petworth tent is taller and so the bedroom poles are definitely taller too. I don't know if you might be able to cut them down?
The other difference, if my memory serves me right, is that the Chatsworth bedroom poles are aluminium with fitted corner brackets, where the taller Petworth ones are steel without the brackets (I think!). You could always clarify this direct with Khyam.
Thanx for your reply. The advert said fits all ridgi dome including petworth and another, i cant remember so went ahead and bought it. As chatsworth is ridgi dome, i thought it would fit. Oh well, back to the search for replacement poles.
