6311 Ergonomic Sit-Stand Chair


The 6311 ergonomic sit-stand chair is designed for jobs that require regular switching between sitting and standing, as well as those that call for a relatively high seat, such as at counters, in workshops, at reception desks, and at laboratory workbenches. For these active work environments, the 6311 chair ensures comfort and ergonomics.

Its “Ergo-shape” seat features a circular, beveled design that relieves pressure points under the thighs and promotes blood circulation. Users can fully extend their legs while keeping their feet firmly on the floor, minimizing pressure points under the thighs and allowing them to maintain an upright, mobile, and dynamic posture.

To accommodate all body types, this ergonomic office chair features height adjustment via a gas lift. It also offers an adjustable backrest.

Two technical upholstery options are available: Stamskin faux leather, which is waterproof, antimicrobial, and resistant to most stains. The PUXX upholstery, meanwhile, is treated to be cleaned with isopropyl alcohol, making it an ideal choice for meeting the hygiene requirements of a hospital environment.

This ergonomic sit-stand chair is available in the 6331 model: the classic backrest transforms into a side-swiveling backrest that can serve as an additional armrest. This provides a solution for specific tasks or precision work requiring support for the upper limb, whether right or left.

Thanks to its wide range of options, the 6331 ergonomic chair addresses numerous challenges specific to each industry.

Stamskin and PUXX

Behind these exotic names lie two high-quality technical upholstery fabrics, which we offer for our seats in the 6311 series.

Stamskin is a high-performance synthetic leather designed for heavy-duty use and specific technical requirements (harsh environments, medical applications, etc.). It is extremely abrasion-resistant and features an antimicrobial treatment.

PUXX, on the other hand, is a flooring material specifically designed for sensitive medical work environments. It is treated to withstand cleaning with isopropyl alcohol, making it ideal for workstations with strict hygiene requirements.
