I did have a little trouble with the tilt lock. After checking installation videos on Youtube I was discouraged because a few people stated that the Dexley is difficult to recline and only reclines so far and that you have to use knee pressure to keep it back. That is not so you have to turn the lock beneath the chair to loosen it to your liking. It was pretty hard to turn a wet washcloth finally did it. You loosen it then use the height level handle pull it out and your chair reclines back very well push it in and it looks in the position that you choose. I love this chair and can fall asleep in it... It’s for my sewing a s craft room.
The chair was easy to assemble and the parts seem solid enough. Head rest and lumbar is adjustable vertically. One con: The lumbar is hard to adjust you need enough force so I can only get the far top setting and the far bottom. But once its set you never have to set it again so I didn't a star for this.
I loved the color and needed something was had more back support. Without having a big and bulky work chair. This chair met the need for that and more. It was easy to put together.
