Office chair Oskar Alba LSO-3332, black, swivel ergonomic task chair with adjustable height and tilt

Oskar Alba LSO-3332 is a black swivel ergonomic task chair designed for daily desk work. The chair combines a cushioned seat and back with a gas-lift height adjustment and a tilt mechanism that allows controlled recline. A five-star base with smooth-rolling casters provides mobility across typical office floors while a compact profile makes the chair suitable for home offices, workstations and meeting rooms where practical, adjustable seating is required.

Advantages

The chair offers adjustable seat height via a gas-lift cylinder and a tilt function to change the back angle, supporting different working postures. Its cushioned seat and back provide basic ergonomic support for prolonged sitting compared with non-upholstered stools. The five-star base with casters ensures stable movement and straightforward repositioning at a desk. The black upholstery and simple design make it visually compatible with a wide range of office interiors.

Suitable for

• Home office desks and study areas
• Workstations in small to medium-sized offices
• Meeting rooms and conference seating where flexibility is needed
• Short to moderate-duration desk tasks such as computer work, paperwork and phone calls

When it may not be suitable

This chair is intended for standard daily desk use and provides basic ergonomic adjustments (height and tilt). It may not be suitable for users who require advanced lumbar support, multi-directional adjustment of armrests, or highly tailored ergonomic features for long-duration or medical seating needs.

Key specifications

• Type: Swivel task chair with tilt mechanism
• Upholstery color: Black
• Seat and back: Cushioned upholstered surfaces
• Adjustment: Gas-lift height adjustment and tilt/recline function
• Base: Five-star base with casters for mobility
• Typical use: Office and home workspace seating

How to use

Adjust seat height with the gas-lift lever so your feet rest flat on the floor and your knees are approximately at a right angle. Use the tilt mechanism to set a comfortable recline; lock the position if a fixed angle is preferred. Sit with your back against the cushioned backrest for support and position the chair so the keyboard and work surface are within comfortable reach. Roll the chair on its casters to reposition at the desk or between work areas.

What to consider before purchase

• Confirm the chair's height range suits your desk and body dimensions
• Check that the basic tilt and height adjustments meet your ergonomic needs
• Ensure floor type is compatible with the included casters or consider a floor mat for delicate surfaces
• Assess whether additional lumbar support or armrests are required for extended use

Usage recommendations

For effective daily use, combine the chair's height and tilt adjustments to maintain a neutral seated posture: hips slightly higher than knees, forearms parallel to the desk, and periodic movement to reduce static load. Use on a level surface and inspect casters periodically to keep them free of debris.
