The SMA Caster V2 ergonomic chair is the perfect synthesis of advanced engineering, premium materials, and health-conscious design. Tailored for professionals working over 8 hours a day, this chair integrates multiple adjustment features, a premium aluminum frame, and state-of-the-art lumbar support to provide a seating experience that is as comfortable as it is supportive.
One of the defining features of the SMA Caster V2 is its durable cast aluminum base. While many budget ergonomic chairs suffer from instability, rapid wear, and an unreliable reclining mechanism, the Caster V2 resolves these problems with premium construction.
Cast Aluminum: Unlike plastic frames commonly used in cheaper chairs, aluminum offers long-term durability, high weight resistance, and a solid, premium feel.
Load Capacity: With a maximum static load of up to 1136 kg, the chair provides peace of mind and unmatched durability.
This solid foundation significantly extends the lifespan of the chair, adds elegance to its overall aesthetic, and provides a more grounded, stable feel while seated.
The mesh seat and backrest of the SMA Caster V2 are crafted from Wintex mesh, imported directly from Korea. This material is a significant upgrade from the coarse, abrasive meshes found on entry-level chairs.
Comfort: Wintex mesh is soft to the touch and gentle on skin, ideal for long-term sitting without irritation.
Elasticity: The mesh remains taut and supportive even after extended use, avoiding the sagging common in lower-grade options.
Breathability: Designed for humid climates like Vietnam’s, this mesh allows superior air circulation, keeping you cool and comfortable throughout the day.
The reclining mechanism of the SMA Caster V2 enables smooth transitions between work and rest. Unlike cheap alternatives that recline too quickly or feel unstable, this chair provides full control:
Adjustable Angle: Recline up to 140°.
Multi-position Locking: Lock the backrest at 90°, 110°, 125°, or 140° depending on your comfort and activity.
Spring Tension: The double-spring tilt mechanism ensures a secure, responsive recline.
This flexibility allows you to switch easily between typing, reading, or taking a short nap – without needing to change chairs.
The 4D headrest on the SMA Caster V2 is fully customizable for optimal neck alignment:
Height Adjustable: Raise or lower the headrest to support different sitting heights.
Tilting Mechanism: The headrest tilts independently at two joints – one on the headrest frame, another at the mounting bar.
Independent Structure: Dual-piece adjustment provides more precise fitting for various body types.
This ensures ergonomic alignment of the cervical spine, reducing tension in the neck and shoulders.
The Caster V2 features a dual-backrest design with a flexible, ABS (Acrylonitrile Butadiene Styrene) lumbar support system, specially developed to maintain spinal alignment:
Dynamic Lumbar Response: The lumbar panel automatically adjusts based on the user's pressure.
Flexible ABS Material: Absorbs and redistributes force to support the lower back consistently.
Hands-Free Adjustment: No manual setup needed – the system adapts in real time to your posture.
This design offers a more consistent and personalized support system than traditional fixed-back chairs, significantly reducing lower back fatigue and the risk of spinal misalignment.
The 5cm height adjustment range of the backrest is ideal for users from 155 cm to 180 cm in height. This allows you to position the lumbar support at the correct spinal zone, optimizing comfort and reducing muscle strain.
Whether you're petite or tall, the Caster V2 adapts to your unique body proportions.
Supporting your arms properly is essential for wrist health and shoulder relaxation. The 4D armrests offer comprehensive adjustability:
Height: Match your desk height or relieve shoulder tension.
Forward/Backward Slide: Customize for typing, drawing, or reading.
Inward/Outward Pivot: Accommodates different working postures.
Lateral Slide: Helps support your arms naturally regardless of shoulder width.
Each armrest movement locks securely in place, offering customized support in all directions.
The seat of the SMA Caster V2 features waterfall-edge design and sliding adjustment to enhance circulation and comfort:
Waterfall Edge: The curved front edge reduces pressure on the thighs, improving blood flow and reducing fatigue.
Sliding Seat Pan: Adjustable up to 5 cm forward/backward for users with different leg lengths.
This duo of features helps eliminate numbness and maintains proper posture, especially during prolonged periods of sitting.
The chair features a Class-4 gas lift, which is the highest quality standard in the industry:
Smooth Height Adjustment: Seamless vertical movement for easy seating adjustments.
SGS Certification: Guarantees safety and resistance to explosion or malfunction.
Durability: Tested to withstand years of use without weakening.
This piston supports users securely and complements the premium build of the chair.
The PU-coated casters on the SMA Caster V2 glide quietly and smoothly over various flooring types:
Noise Reduction: Operates quietly in both home and office settings.
Floor Protection: Won't scratch wood or tile surfaces.
360° Swivel: Allows effortless movement and multitasking at your workstation.
