Product Description

The Yaqi Furniture LHS-2SEAT-FW01 is a 2-seat fixed tiered lecture hall desk-chair unit designed for high-traffic fixed-row public seating environments. It features a coordinated neutral aesthetic, with light wood-look panels paired with a matte grey steel frame, creating a polished, understated look that suits formal public and institutional spaces. Each 2-seat module connects side-by-side to form continuous straight or curved rows, with a vertical center panel separating adjacent seats to define personal space, and a full-height rear modesty panel that doubles as a kick panel for the row directly behind, streamlining row layout and sightlines across tiered floors. Its construction prioritizes long-term durability: the 25mm writing surface uses an E1-grade MDF core with fire-resistant HPL laminate, bordered by 1mm color-matched PVC or PU edge trim. Modesty and divider panels are crafted from 15mm multi-layer plywood with a light wood melamine finish, while tip-up seat panels use 18mm multi-layer solid wood with curved ergonomic edges, supported by 14mm bent plywood internal boards. Support legs and cross beams are formed from 2mm thick cold-rolled steel with a matte grey electrostatic powder coat, and 5mm thick pre-drilled hot-rolled steel base plates enable secure floor anchoring. The hydraulic buffered slow-return tip-up seat mechanism is housed in a black PP plastic cover, folding seats vertically when unoccupied to keep aisles clear, with silent return to avoid disrupting events. Integrated steel wire book nets under each writing surface offer convenient personal storage, and desk edges can be factory-cut to accommodate optional AC power and USB charging outlets; an optional 35mm thick molded polyurethane foam seat cushion upgrade is available for extended comfort. This unit is well suited for tiered university lecture halls, corporate training auditoriums, secondary school multi-purpose halls, public conference auditoriums, standardized exam halls, and government hearing rooms, where its durable build supports heavy daily use. For procurement, note that a minimum 900mm row-to-row pitch is required for adequate clearance, each 2-seat module ships in 2 cartons with a 40-minute per-set reference assembly time, and buyers can select the optional foam cushion or integrated power upgrades to match specific space needs.
