How we assessed it
We synthesized this
The SIHOO M57 is built around structural capacity: a mesh back with adjustable lumbar support on a frame rated to about 150 kg (330 lb). That rating is the point — it gives larger users a chair that holds firm through full working days without feeling stretched, while the breathable mesh and adjustable lumbar keep the lower back supported. It's our pick for anyone who wants more headroom in the weight rating than a standard office chair offers.
The trade-off is extras: there's no included headrest or footrest, and it isn't the highest-rated frame on our shortlist — if you need beyond about 150 kg, the FLEXISPOT BIG MAX goes to 227 kg. Our read is a synthesis of SIHOO's documented rating, mesh construction and adjustable lumbar rather than a hands-on sitting test — see how we test.
