Additional bedding sets available in Latex / PVC not cheap but oh so sexy.
In the old Studio One you had an understair material lined confinement area, could something be made of the current bedroom over stairs cupboard by lining, yes would then require a wardrobe in the room.
Alternatively in the main playroom an L shape lined construction, the l for standing, the _ for laying, please size for the larger man! and unfortunatly that is girth.
Best wishes to P and success to the Forum. M
