Ever since I started working from home my lower back has been sore. I can't fit an office chair in my house. It's a tiny terrace. 2 bedrooms, tiny lounge and dining room. There's nowhere to put a desk and I week from my small dining room table. An office chair would take up so much space and look a bit weird at my dining room table, but I'm worried about my back. Can anyone suggest any solutions? Alternative comfortable chairs that would look semi decent at a dining room table?
