@haeckerfelix I don't have that specific chair but I've had that same issue before, it didn't take me long to figure out it's a problem with static electricity though because I always get zapped when I touch metal after getting up from chairs/couches (I joking call this the curse of Nikola Tesla).
It happens so much that I have a rule/ritual: always touch metal while getting up from a seat (not after!), this way the charge didn't build up in the first place!
