The SIHOO M57 is one of the most impressive budget ergonomic chairs we have tested. At around $179, it punches well above its weight class, delivering lumbar support, breathability, and build quality that rivals chairs costing twice as much. After three weeks of daily use spanning 8–10 hours per session, our backs are genuinely happy — which is high praise for anything south of $300.

The SIHOO M57 is our top pick for anyone building a home office on a budget. The lumbar support alone justifies the price, and the mesh back is genuinely breathable. If you spend serious time at your desk and do not want to spend $500+ on a Herman Miller, this is the chair to beat.
