TN50 Series for Your Home Office






[FAQ] What is a multi-limited tilting/synchronized tilting?
T50 Series is designed in an ergonomic sense to support you all the time. Also, it encourages you to sit in a healthy posture.
(Left) Multi-limited tilting : The chair can be tilted to 5 different angles as you set.
(Right) Synchronized tilting : T50’s backrest is synchronized with your back, following every degree you move.
Lumbar support, a key feature for you.
You may adjust the lumbar support up and down, inwards or outwards so it fits you the most. No gadgets are needed, and you may easily move the lumbar support with your hand.
Having it well positioned, T50 will help you sit comfortable for a long period. Adjust the tilting strength and angle so it fits you most comfortably.
[Seller’s Tips]
Work : Tilting level 1~3 + upright lumbar support
Relax : Tilting level 5 + loose lumbar support
Customizing Your Chair






Tilting Angle Adjustment
This is the lower left lever.
Push the lever down, and lean until you reach the angle you feel comfortable. Then, pull the lever up, and then the chair will be locked to that angle. You can easily change the setting whenever you want.
Multi-limited Tilting Chair
Some people like to lay back and relax on their chairs, while others prefer a straight position.
With T50, you can customize your chair for your utmost comfort.
Tilting Strength Adjustment
This is the lower right lever.
By turning the lever towards your side, the chair will be more easily tilted. By turning the lever outsides, the chair will be more sturdy to tilt.

ERGONOMIC S-CURVE DESIGN: The beautifully-shaped backrest makes your waist remain in an S-shape and prevents back pain while weight on the lumber disk is distributed properly.
EASILY CUSTOMIZABLE : With the advanced multi-limited tilting mechanism, you may set the chair to 5 different tilting angles, and lean to the degree you wish. You can also change the seat slope or slide, and adjust the armrest and the headrest as you wish. These allow you to personalize the chair to your preference.
FRESH MESH BACK : High quality polyester stripe mesh back provides a comfortable seating experience with good ventilation for long term use.
STRONG AND FLEXIBLE STRUCTURE : T50 consists of an aluminum frame to ensure high durability. The parts that touch the body are made of more soft and comfortable materials for your comfort. The seat pad allows you to have a more padded pillowy sitting experience.
