Thanks a ton - some really useful stuff there. My supervisor uses chairs around a coffee table which I think is a step in the right direction, but she has rooms that she shares so there isn't too much leeway. The theraputic value of pets is underated (assuming no phobias!). I absolutely love the idea of sitting out under a tree on a great day - thanks again for the great input - you've no idea how much it helps.
