I previously bought a Hyken mesh chair and had it for 3 years without issues (and sold it when I moved). I've had this new one for maybe a month. Day 1 the left arm rest broke. It's taken 20 days to get a replacement when I was told 5-7. On the same day I got the arm rest the mesh seat caved in. Customer support is professional friendly and quick to answer the phones. However I have no faith in the long-term viability of this chair.
