Adjustable backrest and Slide technology

The chair combines the functionality of an adjustable backrest with advanced Slide technology to deliver maximum comfort. The backrest can be set in one of three positions, allowing you to easily switch from work mode to relaxation and relieve spinal pressure. The forward-backward seat adjustment lets you adapt the chair to your height, ensuring proper posture and reducing pressure on the thighs and knees — an ideal solution for long hours at the desk.

2D lumbar support

The chair offers exceptional comfort with its adjustable backrest and Slide technology. The adjustable lumbar support provides solid reinforcement for the lower back, minimizing the risk of pain and strain. Its height and depth adjustment allows you to find the perfect position that supports the natural curve of your spine.

Adjustable headrest 

The chair is equipped with an adjustable headrest that can be customized in both height and tilt angle. This ensures optimal support for the cervical spine, which is especially important for people spending long hours at a computer. Proper head positioning reduces the risk of tension and neck pain, significantly improving overall work comfort.

3D armrests 

The ergonomic armrests offer three-way adjustment: height, tilt angle, and front-back position. This allows you to perfectly align them with your desk and personal preferences, helping to relieve pressure on your shoulders and arms. Proper arm positioning during work reduces muscle tension and helps prevent wrist pain.

Extendable footrest – relaxation while you work

Thanks to the practical extendable footrest, you can quickly and easily switch to a more relaxing position. It's the perfect solution for those who value the ability to rest during the workday without leaving their chair. The footrest allows your legs to relax, improving circulation and enhancing overall sitting comfort.

Mesh HD fabric – breathable and highly durable material

The specially designed Mesh HD fabric features a thick weave, offering increased strength and resistance to wear. Its open structure allows for free air circulation, helping to prevent overheating even during long hours of sitting.

Class 3 BIFMA gas lift and polyurethane-rubber wheels

The chair features a high-quality gas lift that allows smooth seat height adjustment. The mechanism meets strict BIFMA standards, ensuring durability and user safety. Its solid construction provides stability even with frequent adjustments. Five sturdy wheels made from a polyurethane-rubber blend offer quiet, smooth movement across various floor types.
