My Luna has been great but two questions: 1. The center spoke that adjusts up and down touches the floor , so when I slide the chair across the hardwood or carpet, the clip on the bottom scrapes. Is there a way to adjust that or was it constructed improperly? 2. The back of my Luna is at a much more reclined and steeper angle when the chair is in a neutral, flat position than the chair you show in the video or the one I tested on the showroom floor. Is THAT adjustable,.or was THAT assembled incorrectly? Thanks!

The arms on my chair only go up and down. The right arm moves a smidgen out (not enough to really make a difference) and the left one won't move at all. What am I doing wrong? Thanks!
