I sit with my legs wrapped around my neck while doing breast-strokes. Seriously though, I just sit 'normally'. Both feet under the desk, sometimes I cross my legs at the shins. I sit a little hunched so I have to stretch my back every so often.
depends on where i am, at home i have a sweet chair that i can sink into(it is super sweet)! in my dorm though i have to sit in this really bad chair so i get my slouch on
I used to have a 'normal' chair with my computer, but when my girl moved in with me the whole livingroom got changed and my pc-desk moved with no more room for the comfy chair... *wines* Now I have a 'ouf' to sit on without any back support (which haunts me from time to time) and to make it a little comfortable I have either both feet on the ground or my left foot on the ground and the right one 'locked' behind my left shin. The downside of the pouf is that I sit in a hunched position, hence the back pains from time to time...
Left foot on the floor, right foot on the chair. Left elbow on the desk using my left hand to prop up my head. Right arm leaning on my right thigh and my right hand either on the mouse or arrow keys. Plus copious amounts of slouching.
Ohai necro.
Pretty much this, but I now rest my left elbow on my left thigh, increasing the slouching to levels previously considered unattainable.
I used to have a laptop and when I did I wasn't sitting, I was laying down on the floor or my bed. Now I have a desktop and I sit in a chair and change the way I sit every few minutes, so I guess its random.
