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
1) HEAD
Rested on a head cushion with ears aligned to shoulders.
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
Lumbar should rest comfortably against support while sitting in upright/slightly reclined position.
6) LEGS & KNEES
Feet should rest flat on floor, with thighs flush against the seat and knees bent at 90 degrees.
The lumbar support helps correct my posture – without much fuss.

Steel tube framing for solid structural integrity
Reinforced plywood lumbar support frame for added weight tolerance
Steel-reinforced wheelbase for an unyielding foundation
