Best Ergonomic Office Chairs for Plus-Size Users: Weight Capacity Tests
The Science of Weight Capacity in Office Chairs
When shopping for ergonomic office chairs for plus-size users, weight capacity isn't just a number - it's a critical safety and comfort factor. Our testing reveals that chairs rated for 400+ lbs consistently outperform "standard" 250-300 lb models in:
- Frame durability (steel vs plastic components)
- Base stability (5-star vs 4-star designs)
- Hydraulic cylinder performance
Proper weight distribution prevents premature wear
