I have a herniated disc which causes problems every couple of months or so. I am doing Pilates, trying to be careful. I work in customer service the chair in the office is not great, there's a gap between the chair and the back. No arms, for me to be the right height for the computer I can't touch the ground. The other option is a standing computer but I can't stand for long periods either. Health and safety are going to do a video call with me, can anyone give advice on what I need to ask for?
