Bought myself a standing desk (one that rests on top of an existing desk), a new chair with good lumbar support and a few other office bits and pieces before the end of the tax year in the UK. I didn't think I'd be able to put them through my Ltd Co next year because of IR35 changes, but they have been delayed now.

The only thing I don't have yet at home is dual monitors. Otherwise the setup feels great. 30 Mins sitting followed by 30 Mins standing is doing wonders for my old back
