My equipment arrived on Friday as ordered by the hospital re my forthcoming TKR.
Very useful kitchen perching stool. With a back rest and arms.
Plus a raised toilet seat of 4" depth! I have truly gone up in the world!
(Mind you, I now realise I've probably needed that raised toilet seat for a long time). Both items have been issued to me on a permanent loan basis, but if the NHS ask for them back I'll return them and purchase my own to replace.
Already had a bathroom perching stool and grab rails by the loo so didn't need anything else.
