V40 you! Equipment consulting

Hello? I have to buy my V40 you! before next Monday. But I still have some questions that I could not answer yet. At You! the middle armrest should not be movable. Is that right? Can you use them anyway, or is it too short? Retrofitable? Had in my last car Alcantara/Fabric. The you! has only fabric seats. Can someone tell me if the seats are durable and what are good? Sometimes the fabric quality is indeed rec ht modest and the seats start to walk. The same applies to the side stop. Except for these two criticisms I am otherwise satisfied with the car 🙂 Thank you!
