This is the same seat listed on Husky site and described as -10mm due to improved shape. AOMC must be in error describing it as -30mm

Thanks for confirming!Hello everyone, I installed the heated ergo seat and would confirm that it is a bit lower. But definitely not 30mm. The German homepage also states that it reduces the seat height by 10mm. I have now installed it in the high position, that was too high for me with the original seat.
