I've had a Stokke Duo for 23 years. Varier is a new name for the company and the Duo is a milder version of Varier Gravity Balans [1]. It's been so good that I just recently had it reupholstered. I've tried Gravity and find it excellent as well. With a nudge you can change between four different positions. The positions are quite stable, it's not like a rocking chair.
I've used IRC since 1988 or so, when all the users were from the University of Oulu, Finland. I hang out in a couple of channels of old pals (in IRCnet) and in a few technical channels in Freenode (#sway, #clojure, occasionally others).
I have a tmuxed session that is always connected, and I attach to it from wherever I happen to be. As others have stated, I too find it a non-intrusive, pleasant way to be in contact with certain groups of people.
