Activejet YK848 is a modern office chair combining the best possible ergonomics with an attractive design. Its subdued black colour scheme and elegant design will bring a touch of class to any office or home work corner. Thanks to its universal character and many interesting design solutions, this model will prove useful for students, office workers and people working remotely, ensuring comfort even during long hours of study or work.
ERGONOMICS AT THE HIGHEST LEVEL
The Activejet YK848 office chair is designed to provide comfort to the user and minimise the risk of unpleasant effects of prolonged work at the computer, such as stiffness and pain in the muscles and joints.
The ergonomic design, with a specially separated and contoured lumbar and head section, adapts to the natural curvature of the back, helping to maintain correct posture throughout the day.
The 48.5 × 52 cm wide seat provides comfort and stable support, while the 50.5 × 57 cm high resistance mesh backrest covers almost the entire back for solid support. This makes even long periods of computer work less of a strain on the spine.
6D ARMRESTS
Mounted 6D armrests relieve pressure on the arms and shoulders, making typing easier.
The movable 6D armrests can be raised and lowered (by 7.5 cm), moved forwards and backwards (by 5 cm), rotated left and right by up to 40° of play - all to select the ideal position for your body shape and the task at hand.
ADJUSTABLE HEADREST
Thanks to the full-length headrest section, the Activejet chair provides adequate body support along its entire length, allowing our neck and neck muscles to rest. In addition - for our comfort - the headrest is adjustable: it can be raised by up to 6 cm and rotated by 38°.
3-PART FLEXIBLE LUMBAR SUPPORT
The special 3-part split lower back ensures ideal support for the lower back.
BREATHABLE MATERIAL
The backrest of the chair is made of breathable fabric mesh for excellent air circulation while sitting, keeping the back dry and comfortably cool even on warmer days.
The seat is covered with a pleasant-to-touch upholstery fabric with high-quality foam underneath. This combination of materials means that the chair breathes along with the user - even long hours of work do not cause discomfort due to excessive sweating. Breathable materials translate into greater comfort and hygiene in everyday use.
PULL-OUT FOOTREST
Turn a classic office chair into a full-size lounge furniture with the extendable footrest with soft padding. Unfold the footrest and relax - everyone needs a break sometimes.
SWIVELLING DESIGN
The Activejet YK848 office chair allows you to recline to a maximum of 155° and relax like never before.
ALWAYS ON THE MOVE
Don't like to stand still for too long? Then you couldn't have found a better place!
The Activejet YK848 armchair rotates 360° around its own axis, allowing you to freely reach for objects around your desk without having to get up and leave your workstation. The five-star steel base equipped with five castors ensures smooth movement on the floor - whether you are working at a classic desk or a gaming workstation.
With all these facilities, the chair actively supports you as you move and change position, increasing your efficiency and comfort at work.
TAILORED TO YOU AND YOUR NEEDS
The Activejet chair offers useful features to facilitate daily work and study, allowing you to adapt to your needs.
Thanks to its pneumatic gas lift (class 3 gas shock absorber) and convenient multi-function mechanism, you can easily adjust the height of the seat to the optimum level or change the angle of the backrest to find the most comfortable position behind the desk.
STYLE AND COMFORT
The Activejet YK7848 is an ergonomic office chair that takes everyday office work to a higher level of comfort and... style. With its subdued elegance, the armchair will fit perfectly into both classic and more modern industrial interiors.
