Functions of the Epron Syncron Plus mechanism with seat sliding system:

  • Free floating seat and backrest.
  • Dynamic backrest and synchro seat tilting at the rate of 2:1.
  • Possibility of seat and backrest to lock in 5 positions, allows you to sit comfortably at the desk.
  • Adjustable backrest tilt force allows to adjust the tilt force to the user's weight and provides better seat comfort.
  • Anti-shock protection - preventing backrest from hitting user's back after the release of motion lever. After the motion lever is released, the backrest will not jolt towards the user's back. Lean gently on the back and then the backrest will go back to the starting position.
  • Seat sliding system- i.e. regulation of its distance from the seat to backrest. Between front edge of the seat and back of the knee part there should be the distance of 2cm. It protects against fatigue and sore feet. This feature allows you to adjust the seat to the needs of almost all potential users.
  • Smoothly adjustable chair height.

According to the Environmental Product Declaration (EPD) issued by producer, Epron Syncron Plus mechanism with seat sliding system is 98% recyclable.
