##### SYNC5 MULTI-FUNCTIONAL MECHANISM

## FIVE LEVELS OF FINE-TUNED COMFORT

Adjust your chair to fit your individual body shape, size, and posture. CORE Smart is built with SYNC5, a multi-functional mechanism that allows for 5-way adjustability.

With synchronous tilt, simply lean back to recline the backrest and seat simultaneously for a more comfortable, ergonomic sitting experience.

## SYNCHRONOUS TILT

We prioritize user comfort, so you can simply lean back and relax while experiencing the benefits of our innovative design. Synchronous tilt allows the backrest and seat to move together at the optimal ratio, providing ergonomic support for your entire body.

##### CORE.RDY 180 TECH

## COMFORT COVERED FROM ANY POSITION​

No more tirelessly shifting your body around trying to find the best position for you. CORE.RDY tech is a one-of-a-kind lumbar support that self-adjusts to your posture while you lean to the side and provides ample support for your spine at any given time—ensuring the most ergonomic gaming experience possible.

##### ERGONOMIC HEADREST WITH SIDE SUPPORT

## ENJOY NECK COMFORT FROM ALL SIDES

The design of the ergonomic headrest with built-in winged support keeps your head snugly in place. This semi-circular cushion gives you more positions to rest and alleviates muscle pain while the soft memory foam envelops your head and neck. With our reinforced elastic strap, you can adjust the headrest but it won’t budge when you need it to stay in place.
