Frequently Asked Questions

What does "24/7 intensive use" rating mean?

A 24/7 rating means the chair is engineered and tested for continuous use across multiple shifts — not just a single 8-hour workday. The components, foam, and frame are built to maintain their performance and structural integrity under constant use, which is critical in environments where the same chair may be used by multiple workers across day, evening, and overnight shifts.

How does the MX88IU differ from the MX84IU?

Both are 24/7-rated Maxwell chairs. The MX88IU is the higher-spec model with a taller back height, providing additional upper back and shoulder support — making it the better choice for taller users or those who need more comprehensive back coverage. The MX84IU is the mid-back version suited for standard-height users. Our specialists can help you determine which is right for your team.

What armrest options are available?

The MX88IU is available with no armrests or with KR-200 adjustable armrests. The KR-200 armrests offer height, width, and angle adjustment for proper shoulder and elbow positioning during intensive work tasks.

Is this chair appropriate for healthcare environments?

Yes — the MX88IU is widely used in nursing stations, clinical workstations, and healthcare dispatch environments. Its 24/7 rating and 450 lb capacity make it suitable for the demands of healthcare operations. Contact us to discuss configuration options for clinical use.

Can I configure this chair for multiple users of different sizes?

Yes — the adjustable lumbar, seat depth, seat height, and armrests allow each user to configure the chair to their body dimensions at the start of their shift. We offer ergonomic consulting services to help organizations set up adjustment protocols for shared workstations. Learn more here.
