Scientific Comparison of Synchronous, Multitilt, Fixed Mechanism and Other Systems"},"content":{"rendered":"

One of the issues that users are most curious about when buying an office chair is the design of the chair, which is even more critical than the design of the chair. is a type of mechanism<\/strong>. The mechanism directly determines the seat angle, back movement, the dynamic response of the seat and the level of ergonomics during prolonged sitting.
So the choice of mechanism is not just about comfort; waist health<\/strong>, reduced risk of posture disorders<\/strong>, muscle fatigue management<\/strong> and even work efficiency<\/strong> is a subject of engineering that has an impact on.<\/p>\n

In this blog, we compare office chair mechanisms in detail and analyze which mechanism is suitable for which user with scientific data.<\/p>\n

\n

Why is the Office Chair Mechanism So Important?<\/strong><\/h2>\n

The human body is not suited to being in a fixed position for long periods of time. Sitting at the same angle for hours disrupts the natural curve of the spine:<\/p>\n

    \n
  • \n

    back and neck pain,<\/p>\n<\/li>\n

  • \n

    shoulder tension,<\/p>\n<\/li>\n

  • \n

    thigh and hip pressure,<\/p>\n<\/li>\n

  • \n

    impingement of the disks,<\/p>\n<\/li>\n

  • \n

    circulatory problems<\/p>\n<\/li>\n<\/ul>\n

    and so on.<\/p>\n

    Ergonomic mechanisms ensure that the seat a moving equipment<\/strong> like a spinal column. This movement reduces the load on the spine and gives the muscles opportunities for micro-rest.<\/p>\n

    \n

    Main Types of Office Chair Mechanisms<\/strong><\/h2>\n

    The most common types of mechanisms on the market today are the following:<\/p>\n

      \n
    1. \n

      Fixed Mechanism (Basic Tilt or Fixed Mechanism)<\/strong><\/p>\n<\/li>\n

    2. \n

      Classic Tilting Mechanism (Standard Tilt)<\/strong><\/p>\n<\/li>\n

    3. \n

      Synchro Mechanism<\/strong><\/p>\n<\/li>\n

    4. \n

      Multitilt Mechanism (Multi-Functional Tilt)<\/strong><\/p>\n<\/li>\n

    5. \n

      Torsion Control Mechanism (Tension Control)<\/strong><\/p>\n<\/li>\n

    6. \n

      Double Mechanism Systems<\/strong><\/p>\n<\/li>\n<\/ol>\n

      Below we examine each of them from a technical point of view.<\/p>\n

      \n

      1. What is a Fixed Mechanism? Pros and Cons<\/strong><\/h1>\n

      The fixed mechanism is the most basic mechanism of office chairs.
      It is usually found in affordable seats.<\/p>\n

      How does it work?<\/strong><\/h3>\n
        \n
      • \n

        Seat and backrest are fixed.<\/p>\n<\/li>\n

      • \n

        There is limited or no leaning movement.<\/p>\n<\/li>\n

      • \n

        The seating angle is not changed.<\/p>\n<\/li>\n<\/ul>\n

        Advantages<\/strong><\/h3>\n
          \n
        • \n

          low cost,<\/p>\n<\/li>\n

        • \n

          enough basic support for a short-term session.<\/p>\n<\/li>\n<\/ul>\n

          Disadvantages<\/strong><\/h3>\n
            \n
          • \n

            prolonged sitting increases the lumbar load,<\/p>\n<\/li>\n

          • \n

            dynamic movement is limited,<\/p>\n<\/li>\n

          • \n

            is insufficient to support the posture.<\/p>\n<\/li>\n<\/ul>\n

            Who is it suitable for?<\/strong>
            Use for people sitting 2-3 hours a day or as a guest chair.<\/p>\n

            \n

            2. What is the Standard Tilt Mechanism (Classic Tilt)?<\/strong><\/h1>\n

            It is a higher level of the fixed mechanism.<\/p>\n

            How does it work?<\/strong><\/h3>\n
              \n
            • \n

              The seat and back recline as one piece.<\/p>\n<\/li>\n

            • \n

              There is spring movement.<\/p>\n<\/li>\n

            • \n

              Spring stiffness can be adjusted.<\/p>\n<\/li>\n<\/ul>\n

                Disadvantages<\/strong><\/h3>\n
                  \n
                • \n

                  Since the back and the sitting surface move at the same angle, the upper body cannot fully balance the load,<\/p>\n<\/li>\n

                • \n

                  lumbar support is limited.<\/p>\n<\/li>\n<\/ul>\n

                  Who is it suitable for?<\/strong>
                  Users who sit between 4-6 hours a day.<\/p>\n

                  \n

                  3. What is the Synchronous Mechanism? Why Experts Recommend it in the First Place?<\/strong><\/h1>\n

                  Synchronous mechanism<\/strong>, is the cornerstone of the ergonomic seating category.
                  It is the most recommended system by ergonomics experts.<\/p>\n

                  How does it work?<\/strong><\/h3>\n
                    \n
                  • \n

                    Backrest and seating surface with different rates<\/strong> moves.<\/p>\n<\/li>\n

                  • \n

                    For example, the back moves back 15\u00b0 and the seat moves 5\u00b0.<\/p>\n<\/li>\n

                  • \n

                    This angle difference balances the body weight.<\/p>\n<\/li>\n<\/ul>\n

                    Scientific Advantages<\/strong><\/h3>\n
                      \n
                    1. \n

                      Reduces pressure on the spinal discs.<\/strong><\/p>\n<\/li>\n

                    2. \n

                      Improves blood circulation.<\/strong><\/p>\n<\/li>\n
