TRALT Ergonomic Office Chair with Adjustable Lumbar Support, Black Mesh Back

The TRALT Office Chair is an ergonomic desk chair for home-office work, with depth-adjustable lumbar support and a breathable mesh backrest.

• Depth-adjustable lumbar mechanism — lets you position lower-back support to follow your spine’s curve.
• High-density, high-resilience molded foam seat — is designed to retain its shape through repeated daily sitting.
• Breathable mesh backrest — allows airflow across your back without faux-leather upholstery.
• Class 3 BIFMA-certified gas lift — supports dependable seat-height positioning.
• Reinforced nylon base with a metal core and 330 lb (150 kg) capacity — pairs load support with 360-degree casters for movement across hardwood, tile, and carpet.

For a home office or desk setup, an everyday chair needs to support a seated working position without relying on a fixed lumbar pad or a backrest that traps heat. The TRALT Office Chair combines adjustable lower-back support, a mesh back, and a cushioned seat, with a height range and seat dimensions intended to help buyers assess fit before choosing.

How does the adjustable lumbar support work?

The TRALT Office Chair has a lumbar mechanism that adjusts in depth, so you can position the support to match your spine’s natural curve. Its purpose is to provide lower-back support during longer sitting sessions. The mesh backrest promotes airflow, while the seat uses high-density, high-resilience molded foam designed to bounce back after use.

• Adjustable lumbar depth, rather than a fixed support position.
• Mesh backrest avoids faux-leather upholstery that can peel.
• Molded foam seat is designed to resist flattening and retain cushioning.

Will the seat dimensions and height suit my desk setup?

The TRALT Office Chair has a 19.7-inch (50 cm) wide seat, a 17.3-inch (43.9 cm) seat depth, and a seat-height range of 17.7–21.7 inches (45–55.1 cm). The height range is intended to fit users approximately 5 ft 4 in–6 ft 2 in (163–188 cm), with feet resting flat on the floor. Compare the measurements with your preferred seated position and desk height.

• The seat depth is designed to leave a 2–4 finger gap behind the knees.
• The seat width provides room without making the chair feel restrictive.
• The adjustable seat height helps accommodate the stated user-height range.

What supports the chair, and what is included?

The TRALT Office Chair uses a reinforced nylon base with a metal core and a Class 3 BIFMA-certified gas cylinder. The base has a stated capacity of 330 lb (150 kg), and the 360-degree casters are designed to roll quietly across hardwood, tile, or carpet without scratching or catching. BIFMA basic durability and safety certification is included.

• Clear assembly instructions are included; assembly takes about 15 minutes.
• The chair comes with a 2-year warranty.
• A headrest is not included; the design focuses on adjustable lumbar support, the reinforced base, gas lift, and molded foam seat.

This chair is suited to people setting up a home-office workstation who want adjustable lower-back support, a mesh back, and a seat-height range aligned with their height. It is designed for desk sitting rather than headrest-supported seating, and its fit can be assessed using the stated seat and height measurements.
