We have a new MX and my wife can’t get the seat adjusted so she sits high enough. We’ve had service come out to check the seats and they say they are operating normal. Is there anything we can do? She says she needs 1 extra inch. She puts a rolled up towel underneath her now and sits on that. She says it slips too much with the towel though. I’ll even get her a booster seat if they make that sorta thing.
