Thanks for the advice everyone. I'm still thinking it over. Incidentally Teacheranne, where do you find a maiden who will stand still long enough to let your duvet dry? 
Ha, ha! Did I spell “ maiden” wrong or were you just being amusing? Either way, you made me laugh! I could not think of the more common name, which I have now, clothes horse - which actually seems just as funny!
I’ve actually just bought a Brabantia rotary dryer which can be used at a very low position to dry things such as pillows, flat so I guess I’ll be drying my new Night Owl duvet on it. I’ve had it installed on an area of my patio which I never use so no excuse not to dry my washing outdoors!
