The adjustment is two-stage and it consists in changing this plastic element and inserting the seat into the second position. The most important thing is to show you step by step how to get started. I hope I showed it and it will be helpful for the new user. Thanks for comment. Sorry, the upper sitting position is missing. Forgive me ;)
The video sound is pretty good, beyond my imagination
Thank you for your comment
