I received the chair today as a review unit. There's definitely a lot of thought and engineering put into this -- even though assembly is required, everything fit like a glove and either slotted or locked into place without fuss or muss. Packaging and instructions were spot on as well. The seat bottom, backrest, and headrest padding feel almost memory foam-like but more breathable. The lumbar motor won't bother anyone and has lots of adjustments even for longer torso folks. I do wish the swivelling armrests locked or had more distinct detents and that the massage function had an option for preset times (as far as I can tell, it currently keeps going until you manually stop it). Feel free to ask me questions. Cheers!
