The HAKKAS YB4Z-A office training chair is designed for offices, training rooms, classrooms, meeting areas, study spaces, and flexible commercial environments. It features a 3D breathable PP backrest, ergonomic lumbar support, upholstered seat cushion, height adjustment, aluminum alloy base plate connection, Class 3 gas lift, and nylon five-star caster base.
The YB4Z-A office training chair is designed for offices, classrooms, training rooms, meeting areas, and study spaces that need compact seating with improved sitting comfort. Compared with the basic PP seat version, this model uses a fabric upholstered cushion, making it more suitable for longer learning, meeting, and daily office use. Buyers can also view more related models in our Training Chairs collection.
The chair back uses new PP material reinforced with fiberglass for stable daily performance. Its 3D three-dimensional circular hollow back design improves airflow, while the curved shape provides ergonomic lumbar support for the waist and back. For workplace seating comfort references, buyers can review ergonomic guidance from OSHA.
The upholstered seat uses a multi-layer solid wood bent board base with 2 cm high-density foam and fabric covering. This structure provides a softer sitting experience than a hard plastic seat, making the YB4Z-A office training chair suitable for classrooms, staff training, study rooms, and meeting spaces where users may sit for longer periods.
The YB4Z-A office training chair uses a Class 3 gas lift, allowing the seat height to adjust from 390 mm to 490 mm. This helps the chair fit different users, desks, and learning environments. The adjustable design is practical for schools, offices, training centers, and shared study spaces.
The nylon five-star base with casters allows smooth movement in offices, classrooms, training rooms, and meeting areas. Users can move easily between desks, discussion areas, and training layouts without lifting the chair. Buyers who need more mobile seating options can also review our Office Chairs collection.
The chair frame uses 1.5 mm thick 25 mm round tube with high-temperature baked coating, providing stable support and improved surface durability. The aluminum alloy base plate connection adds structural reliability, while the compact size helps save space in smaller training rooms and office areas. For buyers comparing commercial seating durability, BIFMA standards are also worth reviewing.
With its breathable backrest, upholstered seat, adjustable height, caster mobility, and compact design, the YB4Z-A office training chair is suitable for offices, classrooms, training centers, meeting rooms, study spaces, and public work areas. Buyers can also compare other options in our Meeting Chairs category.
