Combining Comfort with Functionality

Work comfortably with the S5 Chair, an adjustable work chair that is highly functional. K+r shrink meshes back and cushioned seat ensures lasting comfort, with a simple aesthetic that blends with most office styles.

Dynamic Variable Lumbar Support

The lumbar support can be adjusted independently to ensure a customized fit. By providing external support to the lower back, it helps the spine maintain its natural curve while sitting, as well as reducing pressure on the vertebrae.

Responsive Tilt System

Functional tilt mechanism allowing angle adjustments in four positions. Backrest tension can be adjusted up to four levels based on body weight for improved responsiveness and flexibility.

High-density Cushioned Seat

The S5 seat is made of high-density foam and covered in high-quality fabric. The seat depth can be adjusted to accommodate your legs as needed for all-day comfort.

Three-way Adjustable Armrests

The armrests can be adjusted in all three dimensions, allowing you to adjust them by height, forward/backward, and sideways angle. A padded surface is also provided on the top of the armrests to offer you comfort and support.

Lengthened Headrest

The longer headrest provides you with better head support, preventing you from hunching forward, scrunching your shoulders, and stressing your back. An ergonomic headrest makes leaning back and taking a short nap easy.

Mute Casters

Nylon mute wheels roll smoothly on any surface, without damaging wooden floors or your beautiful rug. The non-slip and sturdy caster base helps reduce lower limb pressure and is durable.

Sturdy and Professional

S5 chair features a sturdy frame that is strong and durable as well as a mesh lumbar support that keeps you comfortable for hours on end. It also comes with an ergonomic design and multiple professional adjustments to ensure the best balance of ergonomics and comfort.
