My home office doubles up as a guest room with my parents in law staying relatively regularly, and kids hang out room. I've a little bureau type desk so work things get tucked away at the end of the day but really struggling to find an office chair that has decent back support and an adjustable height but doesn't look out of place in a home. I've seen some lovely bucket, velvet types that look nice but have zero back support and everything else is just so functional. Can spend £200ish quid on the right thing. Any ideas?
