The next time you’re in an office, look at the posture of the employees and the way they carry themselves: Do they walk with their backs straight or do they slouch with their shoulders forward? Some classic chair designs accidentally encourage bad posture, but with a little careful research, both new and used office furniture can solve the problem.

Here are some of the different ways that employers and office managers should address bad posture in the workplace. Keep these points in mind when searching for furniture to add to your office:

  • Encourage the right sitting position: Lifehacker recently spotlighted a VentureBeat video from a conference appearance by Kelly Starrett of CrossFit San Francisco. He advises workers to position their arms by their sides to create a less stressful position. Sitters can then engage their muscles in a way that strengthens them.
  • Find a desk that matches: In a piece for the Express Tribune, physiologist Dr. Rebecca Seguin explains that workers should look at their computer monitors at a 90 degree angle, avoid crossing their legs and keep their feet on the ground. A desk that matches the height and positioning of the user’s office chair will make this easier.
  • Reduce the legs on your chairs: Many chairs have either four legs or a series of wheels. PSFK recently focused on a special chair from Benoit Malta that only has two legs, positioned in a way that forces an occupant to sit up straighter. It harnesses the principle of “bearable discomfort” to force the user to pay more attention to their surroundings and maintain a proper balance.

Paying more attention to the everyday effects of a used office chair or desk will help companies improve their employee’s posture bit by bit.
