Hi.
I finally got around to trying to get 100%, but I'm soooooooo close with only 2 items left. Any help would be greatly appreciated.
Seating: 2, 3, 4 - Wooden Bench - 3m62cm0mm - Found in Hubble Horoscope outside the mansion near the snake charmer.
Workers: 1, 2, 4 - Ant - 1cm5mm - Found in Delightful Dirigible on the floor in the kitchen near the sink (can't believe I missed it!).
I guess I'm good at answering my own questions.
glad we could be of service! :P
