the ability to tilt was difficult and it doesn't tilt back far. Turning the knob was a little hard but once loosened to full capability, it still didn't go back very far.

I bought this for my home office and it works great. Very comfortable and I love how it moves around so easily. The quality for the price is the best part.

I work from home and like playing video games on my PC in my offtime, so I'm always in this chair. No complaints so far, its comfortable and hasnt fallen apart yet like so many of my previous chairs.

Chair is comfortable and adjustments are easy. It did not come with assemble instructions. I had to search for instructions for a model that was similar, that is the reason for 4 stars instead of five

Well constructed. Rolls easily. Seating is comfortable. Allows for adjustment of width of handle bars and back. Back well supported. Back well aerated.

I bought it a month ago. I am 5'3'', that means not a short person, but my feet hang in the air even when the seat is at its lower position. Not very comfortable in that aspect. The back has a curve that gives a back support, which is good.

The seat and back are very comfortable despite my 270 lbs. Seat height, armrest width, arm rest height, and "lean back" tension are all adjustable. I'm delighted with my new chair!

This is the second time purchasing this chair. The first one lasted for 4 years of HEAVY (60 hours/week) use. We only replaced it because one of the plastic bits was creaking and it would startle our baby awake.

Well, this is hands down a great buy for the money. The seat and back are very comfortable. And it has a lot of adjustments for the height and the arm rests.

Back does not stay in place keeps sleeping from selected height. No lumbar support. No way to unlock in order to lean back. Very heavy chair yet seems cheaply assembled mechanism.
