Don't like that armrest? Float test it!
HINT: Mine didn't ... then a particularly helpful member of this Forum sent me his "trinket tray" ... and I never looked back, literally.
The absence of the armrest gives me free, unrestricted elbow movement ... and if I really want an armrest, say on an extended trip, a folded pillow works great! Actually, a Zojirushi mug in the rearmost mugholder also serves admirably :-)
