Bionic Spine Ergonomics
POFIT2 is a clever combination of intelligence and technology, suitable for various office environments. Its ultimate dynamic biomimetic design provides three times more support for the spine, maintaining the correct lumbar angle and truly protecting spinal health from injury. Furthermore, POFIT2 utilizes cutting-edge technology to enable human-chair interaction, guiding users to adjust to the correct position and develop healthy sitting habits, allowing you to find a personalized chair that suits you at any time.
New fifth-generation elastic mesh fabric
The upgraded elastic mesh material offers improved softness, elasticity, and durability. The new mesh incorporates three new zones to distribute pressure, provide soft support, and enhance comfort to manage fatigue. 
Adjustable 5D motion armrests
Now, an upward tilt function has been added to the front part of the armrest to support your forearm when using mobile devices. This is a feature in addition to height, width, angle, and fore-and-aft adjustments. 
Novel functional polymer composite components
It uses a brand-new high-tech functional polymer composite material, which has lower chemical emissions, and is lighter and stronger. 
Back-tracking function
The backrest can now be adjusted forward to support your back while typing or reading. This will be suitable for those who prefer to work in a forward-leaning posture at their desks. 
The MATREX MESH nylon mesh, made using a US patent, is durable and does not deform.
Matrex Mesh is one of the most robust and durable mesh fabrics on the market, woven from strong, elastic polyester fibers to form an intricate and complex mesh structure. The American-made Matrex nylon fiber mesh offers a premium feel, elasticity, and absorbency. Each mesh opening has a very large area, improving heat dissipation efficiency. The mesh structure, utilizing advanced American technology, significantly increases breathability and supportive elasticity. 
MATREX MESH QUANTUM 4.0 vs QUANTUM 3.0
Quantum 4.0 elastomer has greater tensile strength and a denser weave, resulting in better support and less susceptibility to deformation. The excellent elasticity of Quantum 4.0 yarn compensates for the stiffness of the support surface caused by the high tensile strength of the elastomer. Overall, Quantum 4.0 offers better elasticity and stronger resilience for a more comfortable seating experience.
Quantum 4.0 mesh = T168 mesh, Quantum 3.0 mesh = W09 mesh
