hands down best purchase for me was a split keyboard. Had a hard time justifying it, but 2 years in it does wonders in terms of chest/back comfort compared to traditional keyboards.

second best purchase was a quality all-mesh office chair (locally purchased Ioo in my case, similar to aeron). My primary motivation was coping with heatwaves in the southern/top floor apartment (it worked great). Generally high quality and comfort warranted a second purchase for my wife after ~6 years. I was sceptical about ageing of the mesh material over the years, but after ~8 years of use you can hardly tell it apart from a freshly unboxed chair.
