Office Chair Chinese Chair Seat

Admin October 09, 2026

The seat of an office chair is typically composed of wood, sponge, and fabric. Some high-end products adopt special designs and high-elasticity mesh materials to enhance comfort.

Basic Structural Composition

The core structure of an office chair seat consists of three layers of materials. The bottom layer is wood, serving as a support frame to provide basic stability and ensure the seat does not deform under load. The middle layer is sponge, which allows for the adjustment of firmness through different densities and thicknesses. It can cushion body pressure while avoiding excessive sinking that leads to fatigue. The top layer is fabric, which directly contacts the skin and needs to balance durability and breathability. Common materials include polyester, nylon, or leather.

Ergonomic Design Optimization

Some high-end ergonomic office chairs introduce innovative structures in seat design. The front end features a downward-sloping waterfall curve, which reduces pressure on the nerves and blood vessels at the back of the thighs by lowering the height of the seat's front edge, promoting blood circulation in the lower limbs. This is particularly suitable for people who work at a desk for long periods. For example, models like the Sihoo C300 Second Generation Pro simulate the natural sitting posture of the human body, distributing leg pressure more evenly and reducing numbness from prolonged sitting.

Material Upgrade Trends

Mid-to-high-end products are gradually phasing out the traditional combination of sponge and fabric, turning to high-elasticity mesh materials. Such mesh is woven from polyester fibers or nylon threads and offers three major advantages:

  1. Excellent breathability: The mesh structure allows air to circulate freely, preventing้—ท็ƒญ (stuffiness) during prolonged sitting in summer.
  2. Even pressure distribution: The elastic modulus is precisely calculated to adaptively adjust support force with changes in sitting posture.
  3. Strong durability: Its tear resistance is superior to that of ordinary fabrics, and it does not easily sag with long-term use.
    Taking the Sihoo C300 Second Generation Pro as an example, its seat uses a single piece of cloud-like high-elasticity breathable mesh, eliminating seams through one-piece molding technology to further enhance comfort and service life.

Recommended Usage Scenarios

For ordinary office scenarios, a basic sponge seat can be chosen, which is cost-effective and meets daily needs. If prolonged use is required (e.g., more than 6 hours a day), it is advisable to prioritize products with a waterfall curve design or high-elasticity mesh to reduce the risk of muscle strain and varicose veins. When purchasing, one can test-sit to determine if the seat's rebound speed is appropriate and if the fabric is skin-friendly and breathable.
