Haworth Soji Office Chair with Ergonomic Adjustments and Lumbar

In this review the Haworth Soji Office Chair is judged as a solid option for people who spend long stretches seated and need adjustable lumbar support and versatile arm adjustments. The single biggest reason to consider it is its thoughtful ergonomic control set that syncs movement and posture without complicated setup; the chair arrives ready to use and its adjustments - seat height, seat depth, tilt tension and a 4D arm system - cover the bases for most body shapes up to 325 lb. Build quality and sustainability credentials also stand out compared with many standard office chairs.

Key Features

• Ergonomic design: The chair is informed by ergonomics to promote healthier posture and sustained performance during longer work sessions.
• Adjustable lumbar: Built-in lumbar support with an optional 3.5 in adjustment range lets users fine-tune lower back support for comfort.
• Comprehensive adjustments: Seat height, seat depth, back lock and tilt tension control provide individualized positioning and recline feel.
• 4D padded arms: Arms move in four directions so arm position can be tailored for typing, meetings, or leaning back.
• Ready out of the box: No assembly is required, so the chair is usable right away and measures about 28 in wide by 27 in deep and 39-44 in high.
• Sustainable build: Up to 94% recyclable with up to 23% recycled content and certified to GREENGUARD Gold and BIFMA level 3 standards.

Who It's For

The Soji is aimed at professionals and home-office users who want a durable, adjustable managerial chair that focuses on lumbar support and ergonomic controls. Its controls are simple to operate, making it suitable for people who want precise support without spending time on assembly or learning complex mechanisms. Office ergonomics is a natural fit for teams that need repeatable comfort across multiple users.

Those seeking a plush, deeply cushioned executive recliner or a model with forward tilt should look elsewhere, since this model does not include forward tilt and leans toward supportive mesh-backed seating rather than luxury padding. If you need extreme tilt or a highly soft seat, consider chairs focused on recline comfort.
