Kastel Konvert Task High Back Office Chair

Kastel Konvert Task High Back Office Chair

The Kastel Konvert Task High Back Office Chair is an upholstered task chair for people working at a desk in an office or home office. Its defining features are a high back, a synchronous mechanism and 4D armrests, combining a taller backrest with adjustable seating and arm support for everyday desk work.

High Back Design and Fabric

The Konvert’s high back gives you a taller backrest while seated, making it a clear choice if you prefer more backrest above the seat than a low-back task chair provides. The chair is upholstered in Planet fabric, with colour options across grey, beige, red, blue, brown, black, green, pink and purple families.

Its fabric upholstery gives the chair a softer, textile-covered appearance than an exposed hard seat or back. Choose a shade that works with your office palette, whether you want a neutral grey, beige, brown or black, or a more noticeable blue, green, red, pink or purple accent.

Adjustable Task Chair Features

The synchronous mechanism coordinates the movement of the seat and back as you recline, so the chair responds to changes in your seated position rather than remaining completely fixed. Seat-height adjustment lets you set the sitting height to suit your desk and working posture.

The listed design includes 4D armrests, giving you adjustable arm positioning to help make the chair more adaptable to your desk setup. Configuration choices may include versions with or without armrests, adjustable seat depth and a headrest; check the selected configuration before ordering, as these features are not included in every version.

Back-height adjustment and lumbar support are not specified as features, so the Konvert is best considered for its high back, adjustable seat height and synchronous mechanism rather than for those particular adjustments. This distinction helps you compare it with task chairs that explicitly offer adjustable back height or dedicated lumbar support.

For Office and Home Workspaces

The Kastel Konvert task chair suits a desk-based workspace where a high-back design and adjustable arm support are useful priorities. Its fabric choices and alternative base colours—black, white, aluminium or silver—make it possible to coordinate the chair with different office interiors without changing its core task-chair function.

Kastel identifies this model as circular, offering a product choice with a circular designation; no further details about the materials or processes behind that designation are specified. A two-year warranty is provided. Together, these details help you assess the chair’s configuration, appearance and stated warranty when choosing seating for an office or home office.
