The “grey” is more like a dark brown w a grey tint snd the prounced stitching is hemp color.  I am 6’ tall. The chair sits STRAIGHT UP unless I kick out the leg rest a coupld notches. When straight up, there is no support for lower back. only my toes rest on the floor, not the heels of my feet. I dont advise it for people 5’10” or shorter.  Get a lumbar support pillow if you pkan to sit up
