Why buy an office chair from Sit & Sleep?

Because there's no such thing as "the best ergonomic office chair." An office chair only becomes ergonomic when it's fully adjusted and adapted to your body type. The type of chair you choose will depend on the work you do, the intensity of your work, your workstation, and your body type. One of our advisors will select and adjust the right chair for you based on all these characteristics.

Properties of a good office chair

  • Fully adjustable

    An ergonomic office chair should have sufficient adjustment options to accommodate your body's characteristics. The idea that one size fits all goes against the principles of ergonomics. While adjusting a chair may seem complicated, you only need to do it right once. Besides height, seat depth, backrest height, lumbar support, and armrests are also important adjustment options. Since you use your chair for several hours a day, proper adjustment is essential for both comfort and health.

  • Movement

    Our chairs are designed to encourage movement and posture changes, which distributes the load on your spine and promotes rehydration of your discs. This improves circulation, strengthens your muscles, and prevents tension. However, many users lock the chair, often due to incorrect resistance adjustment or simply because they don't know how it works. We understand that too little resistance can feel unsafe, but rather than eliminating movement, it's better to increase the resistance.

  • Open hip angle

    A good ergonomic office chair should also be able to tilt forward to achieve a neutral pelvic and spinal alignment. It's precisely this tilt that makes sitting without back pain possible. Correctly adjusting the chair is crucial here so you don't feel like you're being pressed against your desk. Specifically, this means adjusting the seat tilt forward. For us, this is essential: without this function, we simply can't call it an ergonomic office chair!

Our advisors are trained to adjust the office chair to your individual body type. This way, you'll get the most out of your purchase and avoid back or neck problems. You can even try the chair at home for free for a week!

Go for an ergonomic workplace

A properly adjusted office chair is half the battle. But if you truly want to work ergonomically, your workstation also needs to be addressed. A screen that's too low, an incorrect desk height, incorrect mouse use... There are many things beyond the chair that can still cause problems. Therefore, let our consultants adjust not only the chair, but also the workstation.

  • Height of the desk

  • Distance to the screen

  • Mouse and keyboard placement

  • Positioning at the desk
