Really well packed. One of the most comfortable and tunable chairs I've used. The chair is reasonably strong and comfortable.

The seat shells are embedded in a frame construction. Makes a stable impression. The backrest can be adjusted perfectly using the lever. No problem finding a good sitting position.

This is a very comfortable and supportive chair. At 5'9", 230 lbs I'm not so easy on a chair but this one fits wonderfully and supports my lower back superbly. I'm in it 8+ hours a day and have not the least bit of a backache. This seat on the other hand is not as overall soft but is so much more supportive and firm where it needs to be and my back loves it. The neck pillow is adjustable and fits perfectly under my neck for my height although it can be adjusted higher for taller folks. I also have broad shoulders and that area fits perfectly. I am well pleased with this chair and I would not hesitate to recommend it to anyone.
