The least useful was a complete set of RAF bright orange 3-piece suite chair covers,
I can only say one thing about those chair covers. AAAAARGH! Whoever designed them (and those other dreadful colours) was either blind or a sadist.
I bought a card table (still useful, but we've never opened it up and played cards on it either in my RAF days, or the 25 years since) and the drinks trolley, which my wife has always hated, but she still puts a load of her stuff on it. I also bought a few assorted cutlery items and utensils (some of which are still in regular use in the kitchen for their intended purpose) and I use a pair of thin spring steel bladed dinner knives as gasket scrapers when I'm working on my engines! The standard lamp was converted into a display stand and is used in my wife's shop.
