Here is a detailed introduction to two alloy-frame office chairs:

ergomax evolution2 + Foam Version

• Frame Material: The frame support parts of this ergonomic chair are all made of aluminum alloy, including the mesh fabric parts. The sturdy material ensures the overall strength and stability of the chair. The net weight of the entire chair exceeds 50 jin (25 kg). Independent alloy frame structures are rare for chairs priced under 2,000 yuan, highlighting the uniqueness and high quality of its materials.
• Headrest Design: The headrest features a 2D dual-axis design, supporting height adjustment. The pillow surface can rotate at a large angle, and the pillow axis has a lock, allowing for a wide range of rotation. However, it lacks direct forward and backward adjustment functions, but there are optional headrest accessories available, enabling users to make personalized choices according to their own needs.
• Backrest Features: The backrest adopts a wave design and a three-zone structure. The top section provides support for the shoulders and neck and has a certain degree of adaptive movement. There are four levels of adjustment to change the support intensity, along with height adjustment and a metal clothes hanger, meeting the different needs of users for backrest support and functionality.

enova Alloy Master S Version

• Frame and Mesh Fabric: There is a nylon frame version available, and the mesh fabric is U-MESH, which has good elasticity. This mesh fabric provides a strong wrapping sensation for the head, neck, shoulders, back, waist, and buttocks. It can evenly distribute the pressure from prolonged sitting in all directions and is breathable, offering users a comfortable sitting experience.
• Backrest Functions: The backrest adopts a split design, providing better adaptability for the lower back. The waist area offers different levels of support. The lumbar support can be adjusted in three levels of forward and backward extension, enabling it to adaptively follow the waist's movement. Combined with the buffer springs on both sides of the lumbar support, it achieves four-dimensional buffering, effectively reducing waist pressure. It has a gliding backrest function, which slides down adaptively under gravity and fits the dynamic changes of the waist when leaning back, providing good support for the lumbosacral region and avoiding the phenomenon of rubbing against the back. The backrest also supports 9 cm of vertical adjustment to meet the needs of users of different heights.
• Base Adjustment: It features a wire-controlled quick-adjustment base with four levels of recline intensity. Users can easily adjust the recline intensity according to their usage habits and scenarios to obtain a more comfortable experience.
