Ok girls i have been told that apparently that we can catch thrush from someone else?

when using the same chair eg: like a cinema chair, nylon chair like from buses , or ones that make you sweat ,now then am i being gullible here or what?? because this person reckons that if a woman already has it and has been sitting in this chair for a couple of hrs and another lady comes along and sits in the same chair then she can catch it aswell . so what do you thinks true or bull
