660 Office Chair-Ehang Furniture

There are several different models of the 660 office chair. Here are the main features of three of them:

Warranty and Assembly: It comes with a 5-year warranty and requires no assembly. You can use it right out of the box, saving you installation time and effort.
Height and Angle Adjustment: It uses a pneumatic height adjustment method, which is easy to operate. The maximum backrest angle ranges from 120 to 155 degrees (inclusive), meeting the needs of users in different sitting postures, whether for normal office work or a short rest.
Additional Components: It is equipped with an adjustable headrest, a footrest, and a lumbar support. The headrest's height can be adjusted to provide good support for the neck. The footrest makes it convenient for users to relax their legs during lunch breaks. The lumbar support can effectively support the waist and reduce fatigue from prolonged sitting.
Foot and Armrest Materials: The five-star base is made of aluminum alloy, which is sturdy and durable. The armrests are rotatable and height-adjustable, allowing users to adjust their positions according to their usage habits.
Upholstery Material: It uses leather upholstery, which has a good texture and is easy to clean.

Functional Features: It has dynamic lumbar support and a seat-back linkage function, which can better fit the body's curves and provide dynamic support. It uses breathable mesh fabric, which has good air permeability and is less likely to make you feel stuffy during long sitting sessions.
Angle Adjustment: It can achieve 150° infinite suspension, allowing users to freely adjust the backrest angle to find the most comfortable resting position. It has a flip-up footrest, which makes it easy to switch between office work and lunch breaks with a single button press, meeting users' lunch break needs.

Appearance and Materials: It features a light luxury and minimalist design with light gray fabric and a shiny aluminum alloy frame. The whole chair is well-crafted. The metal five-star base is paired with silent casters, making it smooth and noiseless when moving. The four-level safety pneumatic rod allows for smooth height adjustment.
Core Highlights: It has a Taichi dynamic chassis, and the seat cushion can sway slightly with the body. You can lock the chassis with a single button if you don't want it to sway. The independent adaptive lumbar support can automatically adjust the support force according to the body shape.
Adjustment Functions: The 3D adjustable headrest supports height adjustment and double-angle flipping. The backrest, seat depth, and armrest height can all be customized. The backrest can recline up to 150 degrees at most. Paired with an optional flip-up footrest, you can lie flat for a nap during lunch breaks.
Seat Cushion and Armrests: The seat cushion is filled with a latex + high-density sponge composite, paired with high-elastic breathable mesh fabric, providing high comfort. The multi-functional armrests can be folded. When unfolded, they support the elbows, and when folded flat, they can serve as simple storage trays.
