Frequently Asked Questions

How is the e500 different from a standard ergoCentric chair?

The e500 is purpose-engineered for 500 lb capacity and 24-hour use — it uses a reinforced steel frame, heavy-duty Class 4 gas cylinder, oversized casters, a wider 27" base, and commercial-grade mechanism components not found in standard models. It's not simply a scaled-up version of a regular chair; it's a fundamentally different construction designed for demanding environments and larger users.

Which seat width should I choose?

We recommend selecting based on body width rather than weight alone. As a general guide: 20" for users up to ~350 lbs with a standard build, 22" for users up to ~425 lbs or with a wider hip/thigh profile, and 24" for users up to 500 lbs or those who feel compressed in narrower seats. Our specialists can help you determine the right fit — we offer ergonomic consulting services for exactly this purpose. Learn more here.

Is this chair appropriate for healthcare or clinical environments?

Yes — the e500 is widely used in hospitals, nursing stations, and clinical settings. The vinyl upholstery option supports infection control protocols, and the 24-hour rating makes it suitable for multi-shift healthcare environments. Contact us to discuss configuration options for clinical use.

Can the e500 be used on hard floors?

Yes — oversized casters are available for both carpet and hard floor surfaces. Specify your floor type when ordering to ensure the correct caster is included.

What customization options are available?

The e500 can be configured with your choice of seat width (20", 22", 24"), back height (standard or tall), upholstery (fabric or vinyl in multiple colors), armrest style (standard height-adjustable or 4D), caster type, and optional headrest. We offer ergonomic consulting services to help you select the right configuration before ordering. Book a consultation.

How long does delivery take?

As a custom-built chair, lead times vary by configuration. Contact us before ordering for current lead time estimates. Free shipping is included on orders over $99.

What warranty does the e500 include?
