Mark Adler Junior 4.3 - a swivel chair for children that adjusts to height
Junior 4.3 is an ergonomic children's chair designed for comfort at the desk and a safe, stable position while studying. The adjustments have been designed so that the chair can "grow" with the user in the 90-150 cm height range, while remaining easy to use - even on a daily basis.
Fit range for height: 90-150 cm - ergonomic support for years.
Adjustable seat height and depth - better leg support and comfortable position.
Quick adjustment knobs under the armrests - setting without looking for levers.
Armrests fold 0-90° - easily slide under the desk and save space.
Adjustable, removable footrest - helpful especially for younger children.
Gravity casters - stability when sitting and mobility when standing up.
Breathable materials (mesh) and high-density foam seat.
Assembly without screws - fast, intuitive assembly.
Backrest height adjustment - a seat that keeps up with changes
The backrest can be adjusted according to the child's height, so that the back has the right support at each stage of development. Adjustment is convenient thanks to the knobs located on both sides of the seat - access to the mechanism is located under the armrests, making daily adjustments easy.
Fits the user's height: 90-150 cm.
Adjustment with knobs on both sides - quick and intuitive.
Seat height: 46-56 cm - mechanism activated from 25 kg.
Protection against accidental change of settings during use.
Advanced fit - proper leg support and comfortable positioning
Adjusting the seat depth helps set the right leg support, which promotes comfort at the desk. In addition, the solution synchronizes settings so that as the height of the backrest changes, it becomes easier to maintain an ergonomic, healthy sitting position.
Adjustable seat depth - to fit the length of the legs.
Synchronize settings with backrest height - consistent ergonomics.
Armrests 0-90° - order at the desk and more space
Folding armrests allow you to reposition the chair in seconds. When folded, it can be slid deeper under the tabletop, which helps keep things tidy and works especially well where a child's room has limited space.
Folding range: 0-90°.
Ability to slide the chair completely under the desk.
More convenient use in smaller spaces.
Gravity casters - stability while seated
When the child is sitting, the casters automatically lock under load, increasing stability. When he stands up, the chair regains mobility, and the smooth surface of the casters makes it easy to keep them clean - even with heavy daily use.
Automatic locking under load.
Unlocking when you stand up - free rearrangement of the chair.
Resistance to moisture and dirt, easier cleaning.
Breathable materials and lightweight construction - comfort at your daily pace
The mesh fabric backrest promotes airflow, which helps keep you comfortable even during extended activities. The high-density foam seat is designed to stand up well to regular use and maintain resilience, and the whole thing remains lightweight, so rearranging the chair is not a problem.
Mesh on the backrest - constant air circulation.
High-density foam - resistance to deformation.
Durable, pleasant to the touch upholstery.
Quick startup - installation without screws or tools.
Adjustable footrest - support for your feet when you need it
The footrest makes it easy to set a comfortable position for younger children, providing stable foot support. It can be adjusted and later - when the child grows up - completely removed, leaving the seat in a more "youthful" configuration.
Adjustable to fit the user's height.
Can be dismantled at a later stage.
