“it's a great chair that i find very useful for my style of sitting/moving, i can sit in any direction and lean in any angle, it's helped me a lot. i love it. but i can't seem to lock the caster wheels when i'm sitting on it (they only lock if i stand up...) so i'll tend to get pushed back from my desk if i sit with my knees up :( i'm hoping i'm just missing out an instruction or something because this feature would be really convenient.”
