SIHOO M18 Ergonomic Chair
The budget chair that takes back support seriously.
- High back mesh with dedicated adjustable lumbar support
- 330 lb weight capacity, one of the highest at this price
- Best option for back pain sufferers who can't spend on an Aeron
- 2D armrests are a real limitation, but the lumbar makes up for it
Who It's For
Anyone dealing with lower back pain who needs real lumbar support without a premium price tag. Also good for heavier users. The 330 lb capacity is unusually high for this price range.
Build and Materials
Full mesh back and seat. The mesh is breathable and holds its shape well. High back design means the backrest reaches above shoulder height, which helps people who tend to lean back during calls or reading. Frame is plastic with a solid metal base.
Comfort and Ergonomics
The lumbar is the headliner here. It adjusts in position and firmness, which is rare at this price. The high back and adjustable headrest mean your neck and upper back are supported through long sessions, not just your lower back.
Adjustability
Value
For back pain sufferers on a budget, this chair punches above its weight. The 330 lb capacity alone makes it worth noting for bigger users who are priced out of premium options. The 2D armrests are the main thing you're giving up.
