Sihoo Ergonomic Office Chair M18
M18-M148
Community verdict
The Sihoo Ergonomic Office Chair M18 is widely considered an excellent entry-level office chair that delivers strong ergonomic value for its price. Buyers consistently praise its breathable mesh back, easy assembly, and overall durability through years of daily use. However, taller users and those over 250 pounds often find the chair undersized, noting that the lumbar support can dig uncomfortably into the spine and the seat cushion tends to flatten over long periods.

For the price (under £200) it is a great chair. Someone told me it wasn't as good as a Herman Miller, but then I didn't have to pay over £1000
It really is the best budget chair on the market and has been for a few years.
I'm 6'2" (70kg) and returned my M18 last week - just couldn't get comfortable in it. The backrest frame dug into my back
it realllly digs into my spine and hurts a little no matter how I position it. Just feels way too hard...
