Silvera may earn a commission when you buy through this link. It does not increase your price, and we do not recommend a product because it pays. How we make money.
Why we chose it. The S-shaped seat frame is the reason to buy this one. A flat sling seat lets the pelvis slide forward, which is why people slump in a standard chair after twenty minutes. The Ergo cradles instead, and at 19.8 lb it is still light enough to lift. If the chair is going to be sat in for hours rather than minutes, this is the one.
Is this the right one?
Buy it for
- Longer periods in the chair, where posture starts to matter
- Anyone who slides forward or slumps in a standard sling seat
- Buyers who want light weight without giving up seating quality
Do not buy it for
- Users over 220 lb: the capacity is genuinely lower than most rivals here and this is the specification to check first
- Anyone who needs the absolute lightest option, where the Feather wins by 6 lb
- Self-propelling users wanting a rigid high-performance frame
