Replaced the pivot mechanism again, due to extreme use. Fit like a glove, and fits on older chair models too!

This chair was recommended to me in advance by a friend. The chair comes in a very large package and weighs quite a bit, around 25kg. All items are well packaged and most importantly well protected. The scope of delivery includes everything required for assembly. All individual parts, screws, wheels, etc. are included in the scope of delivery, which means there is no need to buy additional tools for assembly.

I like the chair, however, having a separate cushion for the lumbar support doesn't really work well. It fell over every time I got up. There should be lumbar support built into the back of the chair. I also had to add an ergonomic seat cushion because the seat was very hard. This solved the issue of the lumbar support falling down when I got up because I tucked it behind the seat cushion to hold it in place, but the lumbar support at that low height resting directly on the chair is way too low for a proper lumbar support. It would be well worth paying more for a chair with the lumbar support in the chair and a much softer seat cushion. I like the way the rest of the chair functions, such as the arm rests and way the sides of the chair wrap around.
