Energi-24 Ergonomic Chair Permanent Contact Vinyl Without armrest Height-Adjustable Seat Black 150 kg CT100D/BK 640 x 640 x 960 mm 5

Support that sustains concentration through long shifts

The ergonomic chair offers continuous lumbar support via a permanent contact mechanism that keeps the backrest aligned with movement for uninterrupted support. This design reduces the need for frequent posture adjustments, helping maintain focus during extended tasks. The height-adjustable seat and depth/height back adjustment combine to provide a stable seating posture for extended use.

Tailored adjustments for a precise fit

The seat height is adjustable from 530 mm to 830 mm. The seat depth adjusts up to 450 mm, matching the 450 mm depth of the seat to accommodate different leg lengths. The 490 mm seat width provides balanced support without feeling constrictive. The absence of armrests allows the chair to be positioned close to worktops and reception counters for easier interaction and cleaner sightlines.

Durable construction for demanding environments

The frame is finished in black. The seat and back are covered in vinyl over foam, while metal and plastic components form the supporting structure. The chair is fire-retardant and supplied with five castors for smooth mobility. Self-assembly is required. Overall dimensions are 640 mm width, 640 mm depth and 960 mm height. Weight is 14.9 kg.

Designed for professional settings and broad use

Built for lab, office and reception counter environments, the model suits a wide age range from 16–99 and diverse daily routines. The compact footprint and lack of armrests make the chair particularly useful where space is limited or frequent movement is required. The black finish provides a discreet, professional appearance that integrates easily into modern interiors.

Clear model identity and brand origin

The CT100D/BK model is a practical, performance-focused seating solution from Energi-24. The design balances functional adjustability with robust materials to meet the needs of busy workplaces.

Practical benefits and everyday upkeep

Vinyl covering allows for straightforward surface care. Five castors ensure reliable manoeuvrability across hard and soft floors. The combination of adjustable settings and a permanent contact mechanism delivers consistent comfort and efficient posture support for routine use.
