Not sure if I’m right place thread wise but essentially we are converting the office into a bedroom. Going through the trauma of an extension to build a new office etc. and so for a time DH will have to work downstairs. His office chair is huge and won’t fit in the room / around the table. Are there any ergonomically good chairs which wouldn’t be totally out of place around a dining table? He will likely be using it for a while so want to make sure he doesn’t get the dreaded bad back.
