Aluminum alloy casting frame
The cast aluminum frame provides strength and durability for heavy-duty applications. Its robust construction gives the chair a solid feel and allows for years of use. 
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. 
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. 
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. 
Elastic lumbar support
The lumbar support features adjustable tension control, ranging from soft to strong to suit your preference. The lumbar support remains flexible, providing lateral support that adapts to your movements as you adjust your seat position. 
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. 
Glass Fibre unique chassis
The Glass Fibre chassis features a unique eight-axis design, providing a more comfortable reclining experience. While reclining, it ensures a smooth descent without feet lifting, legs pushing against the ground, or the waist remaining still, making it easy to stand up – an industry-leading technology. 
Adjustable backrest height
The backrest height is now more adjustable, with a 65mm adjustment range and 6 locking positions. This provides a wider range of locking positions to optimize use for users of different heights.
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
