Pretty happy with my setup now.
MacBook Pro with apple mouse and keyboard, all hooked up to a 4k LG 27" monitor that I got delivered from the office. Nice not having to deal with donglegate/a tangle of power cords.
We're in a very small flat so the desk isn't really a proper desk. Its propped up at one end by a couple of books resting on a radiator and at the other end, a well sized sofa. I slot the desk top down the side of the grey chest of drawers at the end of the day and the living room goes back to looking like I don't live at work...
Did have a lovely vintage chair but it was creaky, didn't tilt or swivel so managed to pick up this Ikea for 20quid. Convert to working from home now I have all the creature comforts.
