THE SCIENCE BEHIND THE SEAT

GAMING PERFORMANCE STARTS WITH SOLID SUPPORT

With a stable posture grounded by the Razer Iskur’s ergonomic lumbar support system, you’ll always have a starting point to align the rest of your body around—a fully-realized, adjustable design that reinforces your lower back in a way that fixed backrests and one-size-fits-all pillows can never achieve.

PROMOTING THE IDEAL GAMING POSTURE

With your lumbar support secured, you can then make the necessary tweaks to optimize the rest of your posture using the Razer Iskur’s adjustable height, backrest, and armrests. This provides 3 key benefits:

CONSISTENT EXECUTION

brought about by a highly repeatable sitting position

MAXIMUM RESPONSIVENESS

by adopting ideal arm positions for mouse and keyboard

LONGER PEAK PERFORMANCE

sustained by proper posture that minimizes aches and strains

2) NECK
Kept in neutral position (i.e. not bending forwards/backwards).

3) SHOULDERS & UPPER BACK
Rest upper back on chair, pull shoulder blades together, and release to natural position.

4) ARMS & ELBOWS
Forearms flush on armrest, with elbows bent at 90 to 100 degrees.

5) LOWER BACK

Steel tube framing for solid structural integrity


Reinforced plywood lumbar support frame for added weight tolerance


Steel-reinforced wheelbase for an unyielding foundation
