Picked this bad boy up in store today after a year of using a horrible old chair we had lying around. SUPER easy to put together the screws were all color coded labeled by step and packaged accordingly. Instructions didn't really have any text to guide you but the images were easy enough to follow. Also came with an allen wrench it was all we needed to put it together. Chair is super comfortable great for posture and back support. Not sure how much I'll use the headrest but a good addition. Arm and seat height are adjustable. You can also set the arms' distance from the seat a bit during the assembly. If you push back the chair will go back a little but not much and it doesn't stay/lock there (it bounces back up) so if you're looking for one with more give (I don't need too much personally I wanted the support) you might want to try a different chair. Hoping it'll hold up long term but seeing as I just got it today I can't speak on that unfortunately. Overall FANTASTIC chair. I'm sure my chronic back pain and suffering posture will thank me.
This chair is probably meant for a wide statured person. The arms are only adjustable in a vertical sense so there was no way I could move the arms in closer to my body for this to be an ergonomic setup.
Comfortable chair with lumbar and head support with many custom adjustability options. PRO TIP: Look for Dexley Chair Assembly Video on YouTube from DIY Guy. Simplifies the unboxing/assembly for those of us who don't like to read directions.
