Welcome to the club too, Haras2!
Tablo and Biscuit sometimes like to sleep on a kitchen stool here, which seems to be far too small for their comfort (especially for Biscuit) but they seem happy enough anyway.
I survive the feline foursome by simply letting them get there own way all the time! For example, if I'm trying to read a book in bed but Tablo wants to sleep on my chest, I put the book to one side and spend the next few hours, unable to get to sleep myself, in a thoroughly uncomfortable position while Tablo gets her way (as she invariably does). It's just part of the 'normality' in my life ;-)
