Ergonomic Office Chairs - NEN-EN 1335 Standards

A good office chair is crucial for the comfort of people who spend long hours sitting at a desk. It is an investment that quickly pays for itself through increased productivity and reduced risk of physical complaints. Therefore, it is important to choose a chair that meets the NEN-EN 1335 guidelines, as this standard ensures that the chair can be properly adjusted to the individual body shapes and dimensions of the user.



The NEN-EN 1335 is an European Ergonomic guideline that says something about the dimensions and adjustability of an office chair. A good office chair therefore meets this standard. We will spare you what exactly is stated in the guidelines, but simply put, it comes down to being able to adjust an office chair properly to your fit.

With an office chair that meets the NEN-EN 1335 guidelines, you can be sure that about 85% to 95% of all people, in terms of dimensions, can sit on this office chair comfortably for a long time each day. Of course, this must be set correctly! The key points that are considered are:

  • Seat depth
  • Seat height
  • Adjustable armrests
  • Adjustability of the backrest

All our office chairs meet the NEN-EN 1335 guideline because we understand the importance of this. We offer products that boost your workflow whereby this European guideline is important to comply to.

We will further discuss the important components for the right seating comfort below.Office Chair Adjustable

Seat depth
An important point to consider when choosing an office chair is the seat depth. A good seat depth ensures that the user can fully rest their back against the backrest without pressure on the popliteal fossa. Therefore, it is important to look at the seat depth and whether it is still adjustable, so that it can be adapted to the user's height.

Seat height
Seat height is also an important factor to consider. The chair must be adjustable in height so that the user can keep their feet flat on the ground and bend their knees at a 90-degree angle. This ensures good blood circulation and prevents fatigue and pain in the legs.

Adjustable armrests
Adjustable armrests are also important when choosing an office chair. They must be adjustable in height so that the user can comfortably rest their arms while typing or writing. This prevents the shoulders from being pulled up, which can lead to tension in the neck and shoulders.

Adjustable backrest
An adjustable backrest is also an important part of a good office chair. The backrest must be adjustable in both height and angle so that the user can adjust it to their back. This ensures good support of the lumbar spine, which reduces the risk of back pain.

Materials and Backrest
In addition to these important factors, there are other aspects that play a role in the comfort of an office chair, such as the upholstery, the material of the armrests, and the shape of the seat and backrest. Therefore, it is important to consider all these aspects when choosing an office chair.

When choosing an office chair, it is important to invest in a chair that meets the NEN-EN 1335 guidelines. This standard ensures that the chair can be properly adjusted to the individual body shapes and dimensions of the user, thereby increasing the comfort and productivity of the user and reducing the risk of physical complaints.
