If I could I would give 0 stars... First the chair arrived with a missing part (gas lift handle) which was replaced within a respectable time. Then the gas lift itself failed and now I have a wobbly (hazardous) chair that doesn't lift or drop without failing. A couple of points:
1. This chair is made of cheap parts, the seat itself is nice but the rest of it isn't. The gas lift should not fail within the first few months.
2. Wayfair need to figure things out. The gas lift handle was replaced fine, but when the gas lift itself broke, I was sent all the parts (almost enough to build a new chair) apart from the actual broken component (the gas lift). After multiple request and many months passing (7 months from purchase to date) including providing a clear picture indicating the required piece (red arrows drawn on the picture) I still have a wobbly broken chair... This doesn't give me any confidence in returning as a customer.
