This is yet another one of the situations where two of life's most important tenents clash: never change a running system contra never stop looking beyond.
I sit and write this from my trusted pastel-pink IKEA HATTEFJÄLL. (270 EUR).
However, when sitting in the office I noticed how comfy their chairs are -- hjh Office Chefsessel VENUS BASE (450 EUR)
Asking my friends, they even went beyond, sitting on a Herman Miller Aeron [1000+ EUR]
Now I am stuck in the awkward situation where I like my current chair, but I know there is a world beyond. To be clear, this is not about the money but about the ergonomics and the comfort. One of the lessons I learned in life is that I should not save money on things I use a lot (shoes, bed, toothbrush, keyboard), and a chair where I spent way too much time sitting on also falls into this category.
