NEN office chairs

NEN-1335, also known as NEN-EN-1335, is an important European standard for office chairs. This standard sets specific requirements for the adjustability, dimensions, and ergonomic support of an office chair, ensuring you can sit comfortably and healthily while working.

When an office chair meets the NEN-1335 standard, it means you can rely on a chair that is height-adjustable, has sufficient seat depth, and is equipped with proper back and armrests. These are all essential factors in preventing back pain and other physical discomforts.

At Offeco, you'll find a wide range of NEN-1335 office chairs from renowned brands in various price categories. Whether you're setting up a home office or looking for office chairs for the workplace, our NEN-1335 certified chairs will help you work responsibly and comfortably.

What Criteria Must a NEN-1135 Office Chair Meet?

An office chair earns the NEN-1335 certification only when it meets several strict criteria. These criteria are based on the body profile of 95% of the European population, ensuring that the chair is adjustable and provides the right support for your body. The key requirements for a NEN-1335 office chair are:

  • Adjustable seat height between 40 and 51 cm, with a minimum adjustment range of 12 cm
  • Adjustable seat depth between 40 and 42 cm, with a minimum adjustment range of 5 cm
  • A seat that is at least 38 cm deep
  • A backrest that is at least 22 cm high
  • Armrests that are at least 20 cm long
  • Armrests that are at least 4 cm wide
  • Armrests with adjustable height between 20 and 25 cm above the seat
  • Armrests positioned at least 10 cm behind the front edge of the seat
  • A gap of 46 to 51 cm between the armrests if they are not adjustable in width

When you choose an office chair that meets these requirements, you’re not only ensuring comfort but also promoting long-term health. With the right ergonomic adjustability, you can prevent issues like back and neck pain and concentrate better on your tasks.

Why Choose an Ergonomic Office Chair with the NEN-1335 Certification?

When you choose a NEN-1335 office chair, you're not only getting a comfortable chair but one that is specifically designed to help prevent health issues. Thanks to the extensive adjustability, you can tailor the chair to your body, resulting in better posture and reducing the risk of back, neck, or shoulder discomfort.

The NEN-1335 standard is based on extensive research into the average body measurements of the European population, so you can trust that your office chair will offer optimal support.

An ergonomic office chair with the NEN-1335 certification is also a smart long-term investment. By sitting comfortably, you will stay more productive and prevent discomfort from building up over time. This is beneficial not only for individual users but also for organizations looking to invest in the well-being of their employees.
