Currently having online physio and trying to work standing as my home chair is so unsuited to work and I have health issues. However am not managing to sit or stand for any length of time and am then in too much pain to sleep well. Any suggestions of office type chair I could still buy online at this time that would offer good support without my trying it out. Cant see how I can continue working without something but unfortunately my work is needed otherwise I would not be putting myself through this pain. Thank you for any suggestions.
