Locke
Sunon Locke is an ergonomic task chair designed for people who spend long stretches at a desk and want a chair that responds clearly to changing work patterns. Sunon describes Locke as combining the support of a comfortable office chair with the elegance of a modern office chair to create a personal relaxation experience. In practical buying terms, that means a chair built around controlled recline, lockable focus support, dual-sided lumbar support with 160mm of targeted spinal relief, soft padding, and a 75mm thick seat cushion designed to support without sinking. It also keeps setup and adjustment straightforward with a quick-assemble design and one-second tilt resistance adjustment.

When lower-back support becomes the deciding factor
Back support often becomes most noticeable after several hours, when a chair either keeps you settled or starts to feel less considered. Locke includes dual-sided lumbar support that provides 160mm of targeted spinal relief, and Sunon also specifies soft padding to enhance comfort. Taken together, those details point to a chair designed to give the lower back a more deliberate support zone while keeping the contact feel less harsh. For a buyer comparing ergonomic task chairs, this helps explain how Locke is intended to support longer desk sessions without relying on a generic backrest feel alone.
When fast adjustment saves time and effort
Chair controls are most helpful when they are easy to use in the middle of real work, not only during initial setup. Locke uses an STG quick-adjust chassis with a Mercedes-style paddle shift, and Sunon states that tilt resistance can be adjusted precisely in just one second. The system is also described as simple to use and designed for people who value efficiency. In buyer terms, that means less interruption when you want to change the chair’s feel between tasks. Instead of treating adjustment as a separate routine, Locke is built to make comfort changes quick enough to fit naturally into the workday.
When arm support needs to follow your recline
Armrests can feel helpful while typing but less aligned once you lean back. Locke addresses that with armrests integrated with the backrest, so as you recline, the armrests trace your posture to support your arms. Sunon also states that the 4D adjustable armrests offer height, depth, and rotation adjustments, giving buyers a clearer way to judge whether the chair can adapt to different working positions. For long desk sessions, that matters because arm support should stay usable as your posture changes, not only when you sit perfectly upright.
