Nice and sturdy play seat! I use it in combination with the Fanatec CSL DD 8 nm and V2 Elite pedals. No movement in the frame whatsoever while racing. I also think it looks very cool.
It took a few days before I found a comfortable sitting position. In the beginning, my back started to hurt after half an hour. After a lot of adjustment, I finally found a nice position where I can sit comfortably for several hours. The only disadvantage is that adjustment is not easy and you have to loosen several screws with tools.
What I do find a disadvantage is that the handlebars are not properly adjustable in height. You can tilt the plate on which the handlebars sit, but I find it a bit too high for my taste. I am 1.90m but my partner is a bit smaller. She cannot see well above the steering wheel, so if you are around 1.70m, that is something to take into account.
I also bought the official shifter mount (not via Coolblue because it was not available). This one is also recommended and the lever is very sturdy.
