Why choose an ergonomic office chair?

Good posture is crucial for anyone with a primarily sedentary job. Poor sitting posture can lead to back pain, neck problems, and other health issues. With a properly adjusted ergonomic office chair, you can prevent these issues and improve your health.

Increased productivity, comfort, and support directly result in better focus and higher productivity. An ergonomic office chair ensures that you can fully concentrate on your work without being distracted by physical discomfort.

The combination of stylish deep gray upholstery, a comfortable headrest, and a polished aluminum base gives a luxurious, modern, and professional look to any workspace.

At BENS Office Chairs, we offer a 5-year warranty on all our models. Even after this warranty period, you can rest assured that you will be able to enjoy using a chair that does not creak, squeak, or wobble for many years. Why settle for less when you can have the best? Invest in an ergonomic BENS office chair and experience the difference yourself. Increase comfort, improve productivity, and work with more pleasure!

GREENGUARD GOLD Certificate:
When you think about your health concerning an office chair, ergonomic adjustment options come first to mind. Of course, this office chair meets those criteria. Less often do we think about indoor air quality, where we spend all day, both at home and in the office.

This quality is largely determined by the volatile organic compounds (VOCs) released at room temperature from materials such as carpets, furniture, and building materials. These products can emit thousands of types of VOCs, which end up in the air and our lungs.

GREENGUARD is a scientifically independent institute that certifies products produced sustainably and free from harmful substances, ensuring air quality and well-being. All products carrying the Greenguard Gold certificate fall within strict limits of chemical substances, allowing the manufacturer to fully meet all green and sustainable claims.

We are extremely proud that all our office chairs, as one of the few in the Netherlands, have this certificate.
