My setup:
* standing desk legs from Fully with an ikea counter top. These are fairly expensive legs but they have been very sturdy for me when standing. I hate desk wobble.
* ikea counter on ikea legs for side desk (called desk return, I think)
* Herman miller Aeron chair
* nextstand foldable laptop stand
* merino wool desk mat from BeaverPeak
* MX mechanical keyboard from Logitech
* MX Master 3S mouse from Logitech
* ELLOVEN Monitor Riser from ikea
This picture is a little old. I've cleaned up the cables and cut the side desk to length since.
I recommend that you get a sit-stand desk and a laptop riser. Both make a big difference.
