Most ‘gaming’ chairs are trash material covering shipping foam - garbage.
There are exceptions though. A couple years ago I bought the least gaming looking full leather seat from noble, same foam as good car seats, leather very good, and got it on sale for a silly price. 2 years later it still looks the same as day 1 and the foam hasn’t started to deform yet, I work in it all day.
All my back pain from previous shit chairs was gone in a week too. After that I’d have been happy to pay double.
As in most markets, there are always diamonds in the rough, the hardest part is just identifying them.
Lol was pretty much my first thought.
