Everything you need to know about ergonomic office chairs

to our office chairs

An ergonomic office chair is the foundation of a healthy workspace. Are you looking for a new office chair and coming across terms such as EN 1335, NEN EN 1335 or NPR 1813? On this page, we explain what these standards mean, what the differences are and how to choose the right office chair for your body, your working posture and your daily use. This helps you make a well-informed choice for a comfortable and durable workspace.

Why are EN 1335 and NPR 1813 important?

A good office chair does much more than simply feel comfortable to sit on. When a chair is well matched to your body, it helps prevent back, neck and shoulder problems, improves seating comfort and supports a healthy working posture. That is why EN 1335 and NPR 1813 are important guidelines for ergonomic office chairs. They set requirements for safety, durability, dimensions and adjustment options.

What is EN 1335?

EN 1335 is the European standard for office chairs. The standard describes the requirements an office chair must meet in terms of safety, stability, durability, ergonomics and dimensions. A chair that complies with EN 1335 has been thoroughly tested and is suitable for professional daily use.

Key elements of the standard:

  • Stability
  • Load capacity
  • Safety
  • Durability
  • Adjustment options
  • Build quality

What is NPR 1813?

NPR 1813 is a Dutch practical guideline based on EN 1335. The guideline was developed because Dutch people are on average taller than many other Europeans. That is why NPR 1813 sets higher requirements for the adjustment range of, among other things, seat height, seat depth, armrests and backrest. This makes an office chair suitable for a wider group of users.

When should you choose EN 1335?

EN 1335 is an excellent choice for most users and organisations. If you work at a standard office workstation or share a hot desk with colleagues, an EN 1335-certified office chair will generally provide all the ergonomic support you need.

When should you choose NPR 1813?

If you are taller or shorter in stature, work from home a lot or spend long hours in front of a screen every day, NPR 1813 often offers extra comfort. Thanks to the more extensive adjustment options, the chair can be tailored more precisely to your body.

Benefits of a certified office chair

  • Lower risk of physical complaints
  • More comfort during long working days
  • Tested safety and durability
  • Longer service life
  • A responsible investment

Frequently asked questions

Is NPR 1813 mandatory?

For most users, yes. If you have specific ergonomic requirements, NPR 1813 may be a better choice.

That depends on the user. NPR 1813 offers a wider adjustment range, while EN 1335 is more than sufficient for many situations.
