Check out the most common questions our customers asked. Still have questions ? Contact our customer support.
We typically respond within 24 hours during business days.
Will the chair break or make noise after sitting long?
All-metal reinforced frame with BIFMA/TÜV certification. Features a Samhongsah 4-stage gas lift (2.0mm thick steel + high-purity nitrogen) passed 100,000 lift tests. Rock-solid structure, no noise & no collapse.
Is the 500lbs capacity real?
Absolutely. It’s professionally tested & traceable, supporting up to 500lbs.
Will plus-size users find the seat too small or cramped?
Our heavy-duty chair features an extra-wide seat, far roomier than standard office chairs. It’s fully sized for plus-size users, with no leg cramping even during long sits.
Will the seat cushion sag over time?
Made with high-resilience, high-density molded foam tested for 10,000+ compressions, it stays supportive and never sags, even with heavy, long-term use.
Do the armrests press against the body or hit hands?
The armrests are fully adjustable (height/angle) and flip up for storage, eliminating pressure and fitting all body types and use cases.
Are the wheels noisy or hard to roll?
We use oversized heavy-duty silent casters that roll smoothly and quietly on all floors, with extra strength for plus-size users.
What’s the warranty? Which parts are covered?
2-year warranty on the core metal frame, 2-year warranty on wearable parts (gas lift, foam, casters). Free replacement for non-human damage.
We typically respond within 24 hours during business days.
