DO NOT BUY! It looks nice but that's where it ends. Horrible, horrible, awful design! 
First of all - it squeaks like an old cartwheel. The squeaking is so loud it wakes family members! Second - the armrests: they're designed to move in every possible and impossible direction. It is almost impossible to move the chair by the armrest because the first few feet only the armrest will be moving. The headrest is also super "mobile" and will not stay in place. The tilting - it is synchronous indeed (seat reclines with the back rest) but it is not comfortable like on other chairs I had. Overall - it's a poorly designed chair. I will not recommend.
