Office chair 8-hour test 2026: The 3 best models for all-day sitting

A good office chair for 8 hours a day determines whether you end your workday with back pain or relaxed. In this 2026 test, we show you which three Sihoo models are best suited for all-day sitting in your home office and in the office – and what you should look for in an 8-hour office chair.

How to choose the right 8-hour office chair

Not all office chairs designed for 8-hour workdays are created equal. Before making a decision, consider what's important for you during long workdays:

• Back pain after 4 hours? Dynamic lumbar support prevents tension throughout the day.
• Do you sweat during long sessions? Breathable materials keep you fresh even after 8 hours.
• Tired arms from typing? Adjustable armrests relieve shoulder strain during long working hours.
• Restless sitting? Flexible mechanics allow for healthy movement for hours on end.
• Slouching posture? A stable backrest keeps you upright even at the end of the workday.
• Are your legs numb? An ergonomic chair can improve blood circulation when sitting for long periods.

First steps with 8-hour ergonomics

Sitting for eight hours isn't complicated, but it's different from short meetings. The key is proper preparation. Most problems can be avoided with a good setup.

Just get started. First, get used to your Sihoo – test all the settings, understand the levers, and learn your optimal position. Practice makes perfect.

Then take your time. Hectic schedules lead to tension. When working an 8-hour day, fluid movement is essential for survival.

Keep these points in mind:

• Set up your Sihoo before your first day of work.
• Use the 30-30-30 rule: Stand up for 30 seconds every 30 minutes.
• Monitor at eye level for optimal ergonomics
• Make full use of all adjustment options

Recommended 8-hour accessories

To get the most out of your Sihoo:

• Footrest (for people under 170cm)
• Monitor arm (for perfect screen height)
• Desk lamp (for optimal lighting)

Settings tips

• S300: Use all 6D functions. Anti-gravity mode for relaxation.
• S100: Adjust both lumbar support sections separately. 135° for breaks.
• C300: Start with automatic weight adjustment. Use single-lever control.

Avoid sudden movements. Consciously change your position every 2 hours.

FAQs

Can I really sit for 8 hours without breaks?
