Long term lurker here. Finally got myself a proper ergonomic chair in the Steelcase Series 2 last month. This is an option that fit my budget ( <RM2k ) and I wanted something with a breathable back and a solid built that lasts. I was initially looking at the ergohuman, but had concerns that the mesh might sag after years of use.

Coming from a 5 year old Ikea Markus, I feel that the seat cushion is firmer and less plush-like but not "hard". My Markus cushion started sinking after 5 years of use causing some tailbone and lower back pain ( I sit alot for work ) . So this is a welcomed improvement in support. Build quality is rock solid and the armrests are a clear step up. The flexible back support hugs my back properly and adapts so that I'm supported throughout the work day. Took me a few days to adjust my posture to the new chair but after I adapted I can't go back. I miss the Markus's tilt lock mechanism for lounging and relaxing tho. Series 2 has no tilt lock.

The Markus for the price is an overall good budget chair and all the mechanisms held up the past 5 years. Ergonomically, its not too bad either but you need to be a tall person to fit else you'll have a hard time. Watch out for the seat cushion if you are a heavy user.

All in all satisfied with my upgrade and just want to share my experience

Yup, the price was really what made my decision for me. How's the secretlab so far?
