Overall, I am very happy with this purchase. Assembly was fairly simple and the instructions along with the picture guide are both very easy to follow. The headrest is easy to position and offers great comfort. The wheels of this chair offer smooth mobility and the swivel and tilt features are also excellent. I have been using the chair for 1 week now and I love it very much. Providing maximum comfortability. It is definitely a great chair and I do not face any problem with it so far. Not sweating as leather material of the old chair. It’s also easy to assemble because everything is included and the instruction is easy to read.
