Today, before I even sat down at my desk, I learnedhow to evacuate someone from my office using an evacuation chair.
I want one!
Basically its a metal deckchair with wheels on it so you can use it like a wheelchair but when you hit stairs its got runners on it and you slide down them like your sitting on a teatray. Obviously theres a method of breaking but unfortunately you need someone behind you like in a dog sled to use them.
I still want one though.
