TRALT Ergonomic Mesh Office Chair, White, with Adjustable Lumbar Support

The TRALT ergonomic mesh office chair is designed for home-office and desk work, combining adjustable-depth lumbar support with a seat-height range of 17.7–21.7 inches (45–55.1 cm).

• Depth-adjustable lumbar mechanism — lets you position lower-back support to follow your spine’s curve.
• High-density, high-resilience molded foam seat — designed to maintain its cushioning and shape beyond one year of use.
• High-tension mesh backrest — allows airflow through the backrest while avoiding peeling faux-leather upholstery.
• Class 3 BIFMA-certified gas cylinder — holds the selected seat height during use.
• Reinforced nylon base with a metal core and 330 lb (149.7 kg) capacity — provides a reinforced foundation for sitting.
• 19.7-inch-wide (50.0 cm) seat and adjustable height — accommodates a range of desk setups and user heights.

Long periods at a desk can make lower-back support, seat cushioning and airflow important parts of a chair’s fit. The TRALT chair brings these features together for home-office work and other desk-based routines, with adjustable lumbar depth and a mesh backrest rather than fixed back support and faux-leather upholstery.

What supports comfortable sitting during desk work?

The seat uses high-density, high-resilience molded foam, while the backrest is made from high-tension mesh. The molded foam is designed to bounce back after use and avoid flattening after one year; the mesh promotes airflow through the backrest, which can help reduce heat buildup in warm environments. The mesh also avoids the peeling associated with faux-leather upholstery.

• The seat is 19.7 inches (50.0 cm) wide and 17.3 inches (43.9 cm) deep.
• The seat depth is intended to support the thighs while leaving a 2–4 finger gap behind the knees.
• The mesh backrest has a professional appearance.

Can I adjust the lumbar support and seat height?

Yes. The lumbar mechanism adjusts in depth so you can position it to match your spine’s natural curve, rather than relying on a fixed support. Seat height adjusts from 17.7 to 21.7 inches (45–55.1 cm); the chair is intended to fit users approximately 5'4" (163 cm) to 6'2" (188 cm), with feet resting flat on the floor for proper posture.

• Adjust the lumbar depth to suit your lower-back support preference.
• Compare the chair’s seat-height range with your desk and preferred sitting position.
• Use the seat-depth guidance to leave the recommended space behind your knees.

What supports the chair, and what is needed to set it up?

A Class 3 BIFMA-certified gas cylinder supports seat-height adjustment, and the reinforced nylon base has a metal core. The 360-degree casters are designed to roll quietly across hardwood, tile and carpet without scratching or catching. BIFMA basic durability and safety certification is included.

• The base is rated for a capacity of 330 lb (149.7 kg).
• Assembly takes about 15 minutes and uses the included clear instructions.
• A 2-year warranty is included.
• This version does not include a headrest.

This chair best suits home-office users looking for adjustable lower-back support, a breathable mesh backrest and a seat-height range that fits their desk setup. Its molded foam seat, depth-adjustable lumbar mechanism and metal-core reinforced base are the defining features for desk-based sitting.
