Who should skip it
Skip this model if you require adjustable armrests. The fixed arms cannot be raised, lowered, or moved forward. You might also look elsewhere if you need a high-back design for full shoulder support.

Key specs explained for this chair
Fixed Arm
The armrests do not move or adjust. This design choice prioritizes structural stability and durability over customization. You get a solid, rigid support system that resists wobble during typing or leaning. This is ideal if you prefer a consistent arm position and want to avoid the mechanical complexity of adjustable joints. It simplifies the chair's structure, potentially extending its service life.
250 pounds weight capacity
The chair is engineered to safely support a maximum user weight of 250 pounds. This limit is enforced by its sturdy base and BIFMA-certified gas lift. You should verify that your body weight falls within this range to ensure safe operation and prevent mechanical failure. This capacity is standard for many mid-range office chairs, offering reliable support for average-sized adults.
16.7'' to 19.7'' seat height
The seat cushion adjusts vertically within a three-inch range. This allows you to raise or lower the chair to match your desk height and leg length. You can achieve proper ergonomic alignment where your feet rest flat on the floor. This adjustability helps accommodate different body types and desk configurations, ensuring your thighs remain parallel to the ground for better circulation and comfort.
90°-120° tilt mechanism
The backrest reclines between ninety and one hundred twenty degrees. This range lets you lean back for short breaks or deeper relaxation without leaving your desk. You can customize the resistance using the tension knob to match your weight. This feature supports dynamic sitting, allowing you to shift positions and reduce static pressure on your spine during long work sessions.
Design and build specs
The DUMOS chair uses a mid-back mesh design to support your spine. The listing states the breathable mesh promotes air circulation, which helps keep you cool during long work sessions. The seat cushion is made of high-resilience foam, described as providing comfort without sinking over time. This combination aims to balance airflow with structural support for your lower back and hips.
According to the listing, the chair measures 21.5 inches wide, 22.2 inches deep, and 38.2 inches tall. It weighs 21.6 pounds. The height adjusts from 16.7 to 19.7 inches. The fixed armrests enhance stability and durability, though they do not move. A storage space at the back allows you to hold books or tablets. The base supports up to 250 pounds and includes a BIFMA-certified gas lift for safe height changes.
Movement is handled by 360-degree silent casters that protect floors. You can recline between 90 and 120 degrees using a tilt mechanism. A tension knob lets you adjust the recline resistance to match your body weight. Assembly is listed as taking about 15 minutes with included tools. The finish is grey and black. These specs suggest a practical setup for standard desks, focusing on stable support and basic ergonomic adjustments rather than extensive customization.

Before You Buy This Chair
This DUMOS chair fits standard desks with its 21.5-inch width and 22.2-inch depth. You must verify your desk height accommodates the 16.7 to 19.7-inch seat range.
