Our work is largely behind the PC or laptop. Often on a chair. Lying on the couch is also an option, but we don't recommend it. Anyhow, sitting at a desk is not the best thing for your body. But if you do, make sure you are sitting properly.
We've made sure you have good chairs and adjustable desks. Here is a link to how you can adjust them to best suit you. And click here for some additional information from an ergonomist. Don't forget to stretch your legs and arms in between working sessions. Or stand on your head for a while, it seems to be good for some extra blood flow. No kidding; if you need anything else, so that you can sit comfortably without suffering from all sorts of aches and pains, let us know.
