For years I have been working from home 2-3 days a week. So far I haven't had a proper home office setup. Instead I have been slouching on the couch or occasionally using our kitchen table. Not the most ergonomic setup, but fine as long as I haven't had to spend more than 1-2 days in a row there.
Now, the situation is different: I work here five days a week, every week. I'm starting to feel the effect in my back and neck. Luckily my employee is up to date and flexible with the current situation and it's ok for us to get anything we need from the office to setup our home offices for now.
So during the long weekend I drove up to our office and loaded the car with an adjustable height table, saddle chair and nice, big external monitor (the ones I'd use when working at the office). So now I have brought my office setup as-is into our home and can work just the way I used to also in here.
