I love the all over mesh on the seat and back seat feels good; had for two weeks now and feels solid was easy to put together- though I think the angles of the screws were not were I thought they should have been
It's a really comfy and ergonomic chair. I purchased 3 year warranty in case the mesh is damaged by anything sharp as the store staff recommended. But when I came home and actually started using it I don't think the warranty is necessary. It's a very high quality chair. The mesh is made by sth very durable and solid it feels like some sort of plastic instead of any kind of soft fabric. I don't really think the mesh can be damaged easily so don't worry about it!
I really like this chair. It's comfortable well-made and easy to assemble. If I had to nitpick I wish the arm rests were just a smidge further out but that probably says more about how I sit in chairs than the product itself.
