Steelcase Amia 브라운 가죽 - 플래티넘 프레임 (재생)

Product Feedback: Steelcase Amia (Brown Leather, Platinum Frame)

I have been using the Steelcase Amia for approximately 14 days in a home office environment with an adjustable-height desk.

Construction & Mechanical Quality

The chair demonstrates strong build quality. The leather upholstery and platinum frame present a premium appearance and feel durable in daily use. All mechanical components — including seat height, seat depth (slider), recline tension, and lumbar height adjustments — function smoothly and are intuitive to operate. The seat cushion provides consistent support and distributes weight effectively without noticeable pressure points.

Lumbar Support & Backrest Contour

From an ergonomic standpoint, the backrest presents a neutral contour profile. While this design may accommodate a broad range of users, I found that for a smaller frame (5'1"), the default lumbar depth was slightly insufficient to fully engage my natural spinal curvature.

Without modification, I experienced a subtle sense of postural effort — specifically, a need to engage stabilizing musculature rather than fully relaxing into the backrest. After introducing a slim lumbar insert positioned horizontally at the thoracolumbar junction (approximately 4–6 inches above the seat pan), support improved meaningfully. The additional depth enhanced pelvic anchoring and reduced muscular guarding.

This suggests that while lumbar height adjustment is effective, additional lumbar depth adjustability may benefit smaller-framed users or those requiring more pronounced contour support.

Armrest Configuration

The armrests on this model are height-adjustable only and fixed in width. For a narrower shoulder frame, the armrests are positioned relatively wide. As a result, I am unable to use them comfortably during typing tasks without encouraging shoulder abduction (elbows drifting outward). This limits ergonomic optimization during active desk work.

Users with narrower builds may benefit from inward width adjustability or optional narrower arm configurations.

Functional Performance

With lumbar contour appropriately adjusted via a slim insert, the chair performs well during focused work sessions. Seat depth adjustment is particularly valuable for shorter users, and the recline mechanism provides smooth, controlled movement.

Overall stability and seat comfort are strong. The chair’s neutral back design offers versatility but may not provide a more contoured or “enveloping” feel without minor customization for certain body types.

Overall Assessment

The Steelcase Amia is a well-engineered, high-quality ergonomic chair with strong foundational adjustability and premium construction. For smaller-framed users, incremental improvements in lumbar depth adjustability and armrest width flexibility could further enhance ergonomic performance.

With minor customization, the chair provides stable and comfortable support suitable for extended use.

Very satisfied with this purchase. Chair is in excellent shape with just a few blemishes that are hardly noticeable. The new casters and hydraulic cylinder are great!
