Nice supportive memory foam base which is well ventilated.  Locking recline function is a great surprise, very precise and solid and on max makes for a good relaxing chair which I wasn’t expecting!  Medium-Soft padded arms, nice adjustable headrest. Solid build, you feel like you’re sitting in a well constructed, ergonomic chair.  Really appreciate the build feel and the smooth adjustment functions.  Very happy for the money and beats all other chairs I’ve used before.  Comfy sitting in this with my feet up on a stool and equally so for desk work, too which is just as important to me.
