SINC 2 is the back-support-focused model in the SINC family, combining more defined lower-back contact with Smart-Glide™ movement and extensive body-fit adjustment.
Height is only a starting point. Actual chair fit also depends on thigh length, torso length, lumbar position, shoulder position and headrest reach.
SINC 2 is designed for users who prefer clearer lower-back contact and greater control over their support settings, while still being able to move between focused sitting and recline.
Smart-Glide™ allows the backrest to glide with your body as you change posture, helping the support stay in closer contact with your back instead of remaining completely fixed.
The Smart-Glide™ movement is separate from the chair’s recline function. You can allow the backrest to move freely, or use the Smart-Glide™ control to choose a fixed support position.
Leave Smart-Glide™ unlocked for continuous backrest movement, or lock it at either the upright/original position or the lowest Smart-Glide™ position.
SINC 2 is the only chair in the SINC family that allows Smart-Glide™ to be locked at its lowest position.
Use Smart-Glide™ freely when you want the backrest to follow your movement, or lock it when you prefer a more stable support position.
SINC 2 uses two responsive lumbar-support sections to create more defined lower-back contact, with additional depth adjustment to fine-tune how closely the support meets your body.
Instead of one flat lumbar surface, the Twin-Support Dynamic Lumbar uses two separate support sections that respond independently to changes in lower-back shape and movement.
The left and right lumbar sections can respond independently, helping the support maintain more natural contact with the lower back.
SINC 2 is tuned for users who prefer a clearer, more support-focused lumbar feel.
Turn the lumbar adjustment knob to move the support approximately 2 cm forward. This lets you choose a gentler or more noticeable level of lower-back contact.
Keep the support farther back when you prefer a lighter lumbar feel.
Move the lumbar support forward when you prefer closer lower-back contact.
Adjust the lumbar depth until the support feels present without creating excessive pressure.
SINC 2 uses the same Dual-Axis structure as Niture’s 5D armrests, with an additional 20° pad-tilt adjustment to create the 6D version.
The armrest combines 360° pad rotation with up to 270° pad pivot. These two rotational axes form the Dual-Axis structure and allow the arm pad to reach a wide range of positions around the body.
Together, the two axes create up to 54 cm of fore–aft positional reach without relying on a long straight sliding track.
The 5D and 6D versions share the same Dual-Axis rotation, pivot and positioning structure. SINC 2 adds up to 20° of pad tilt as the additional adjustment dimension.
Raise or lower the armrest to better align elbow support with your shoulder and desk height.
Tilt the arm pad to better match different forearm angles.
Rotate the pad through a full circle to change its orientation around the forearm.
Pivot the Dual-Axis structure to reposition the arm pad across a wider support area.
The combined rotation and pivot provide up to 54 cm of total fore–aft positional reach.
Adjust the armrest width to better match body width and elbow position.
People of the same height can have different torso, thigh and neck proportions. SINC 2 lets you adjust these areas separately instead of relying on overall height alone.
The backrest adjusts through 4 levels across a 6 cm range, helping position the lumbar and upper-back support higher or lower to suit different torso lengths.
Set the backrest so the lumbar support meets your lower-back area naturally rather than choosing a position based only on your total height.
The usable seat depth adjusts through 4 steps from approximately 44 to 50 cm, allowing you to change how much of the thighs are supported.
Aim for good thigh support while maintaining comfortable clearance behind the knees.
The physical seat structure is approximately 53 cm deep. The 44–50 cm figure refers to the adjustable usable seating distance.
The headrest adjusts in depth, rotation and tilt so it can be positioned around different neck positions and sitting angles.
Move the headrest forward or backward to adjust its reach.
Rotate the headrest to change the contact angle.
Tilt the headrest for different upright and reclined positions.
Position the headrest so it supports the neck area without pushing the head excessively forward.
SINC 2 is generally recommended for users around 145–190 cm, but actual fit also depends on thigh length, torso length, lumbar position and headrest reach.
SINC 2 moves from focused sitting into supported recline with multiple locking positions, synchronized arm support and optional leg support for short recovery periods.
SINC 2 provides 4 recline locking positions, allowing you to move from upright work into progressively more relaxed sitting positions, with a maximum recline angle of up to 145°.
The armrests move with the reclining structure, helping maintain more consistent forearm support as your sitting angle changes.
SINC 2 is available with an optional retractable footrest for additional lower-leg support during deeper recline and short recovery periods.
An integrated mini footrest also provides another position for the feet when you want to vary leg posture without extending the main footrest.
Extend it when you want additional lower-leg support during deeper recline or short breaks.
Provides a secondary place to reposition the feet during more relaxed sitting.
A breathable, responsive mesh surface used across SINC 2’s seating and support areas.
Class 4 gas lift for seat-height adjustment and everyday structural support.
Smooth-running castors help the chair reposition more quietly during normal desk use.
Move between upright work, supported recline and short recovery positions instead of staying in one posture for the entire day.
Each SINC model has a different support character. Choose based on how much lower-back contact, adjustment control and recline support you prefer.

| SINC Lite | Users entering the SINC system | Accessible, adaptive support | Yes | More accessible Smart-Glide™ entry with adaptive support and footrest included. |

SINC 2 is the back-support-focused model in the family, designed for users who prefer more defined lumbar contact and greater control over how that support feels.

Physical seat depth describes the seat structure itself. Usable seat depth describes the practical seating distance available to support the thighs.
The maximum 145° recline refers to the included angle between the seat and backrest at the deepest reclined position.
The approximately 2 cm value refers to how far the lumbar support moves forward from its rear position.
The 6 cm range is measured between the lowest and highest backrest-height settings.
The 54 cm fore–aft reach is created by the combined 360° pad rotation and 270° pad pivot. It is not a 54 cm straight sliding movement.
Physical chair dimensions are manually measured and may vary slightly between measurements.

Compare them based on support feel and body proportions rather than specifications alone. Seat depth, lumbar position, headrest reach and armrest range can all affect which model fits you best.
Specifications help narrow the choice, but the final fit depends on your body proportions and preferred support feel.
Adjust seat depth, backrest position, lumbar contact, armrests and headrest around your body.
