You may choose among 4 types of casters to adapt your seat for CPE and daycare work. Multisurface nylon casters will suit all kinds of floor, including carpets, while urethane casters for hard floor will be used on wood or ceramic tiles.
Lock-off casters for hard floor are well appreciated while working with toddlers and small children, since they automatically brake when nobody is seated.
Glides are useful for specific tasks which require stability, instead of mobility,
Hard floor casters are made of urethane (rubber) and provide a smoother ride on a wood, cement or ceramic floor. Carpet casters can be used on a hard floor, but the reverse is much more difficult: urethane casters on carpet will create too much friction and you will have difficulty moving around while sitting in your chair.
The cylinder is the component that allows you to adjust the height of your chair. The standard cylinder allows you to adjust the height of your chair from 17″ to 22″ (43 cm to 56 cm) from the floor to the top of the seat. If you need your chair to go lower than 17″ (43 cm), you should choose the short cylinder, which adjusts the height of the chair from 16″ to 20″ (41 cm to 51 cm).
The Quatra’s multi-function mechanism includes a slide to adjust the depth of the seat, and the standard configuration will fit most people. However, if you are 5’2” (1.57 m) and under, you will need a short seat, and a long seat if you are over 6’2” (1.88 m).
The useable depth of the seat is determined by the backrest blade:
The standard 20.5″ wide seat will fit most people. If you are slim and not very wide in the shoulders, then you should opt for a narrow 18.5″ wide seat.
The standard 20″ wide seat will fit the vast majority of people. However, depending on your height and build, another seat size may be more appropriate for you. The table below can help guide you in your choice of seat size:
Size and shape
Small and slender
Corpulent or strong hips
The armrests on office chairs are often too far out, requiring the arms to be spread out to rest on them. It is recommended to work as close to the body as possible: the laterally adjustable armrests can slide inwards, to get closer to the body.
