The massage unit is so loud it's like sitting beside a lawnmower.
Can't set tilt farther back.  Chair wants to lean forward instead of sitting level to the floor and staying that way.  Moveable arm rests are annoying - you can't use them to reposition yourself without having to find the center of its gravity - and you NEED to reposition yourself A LOT - especially considering the seat tilt always wanting to lean you forward in your seat whether you like it or not.  This chair is not right for me. 
Instead of the extreme hassle to disassemble and ship or return it fully assembled,  I decided to accept a 20% discount to keep it instead.   My mistake.
