产品描述

This fixed link row seating with integrated writing desks, model LHR-DK925is purpose-built for high-traffic public learning and assembly environments, delivered as an unbranded lecture hall fixed seating solution. Its visual design follows a cohesive, formal aesthetic, with a coordinated palette of dark green upholstery and structural accents paired with light wood grain finishes on backrests, complemented by light gray support components and dark gray under-seat elements. Numbered end panels on each row support straightforward seat assignment, while vertical dividers between adjacent seats create clear, defined personal space for every occupant. The fixed, row-connected layout installs directly to flooring, with staggered height configurations suited to tiered spaces to preserve unobstructed sight lines to a front presentation area. Construction balances robust durability and long-term usability, starting with die-cast aluminum end support stands treated for anti-oxidation and finished in a smooth powder coat. Cross support beams use cold-rolled square steel tubing bolted securely to end stands, with zinc-plated expansion bolts for floor fixing concealed by matching plastic end caps for a clean, finished look. Seat and backrest panels use multi-layer hardwood cores clad in fire-resistant laminate, with aluminum edge trim on backrests and edge banding on writing desks to protect against impact damage. Seat cushions feature high-density polyurethane foam upholstered in dark green fabric, while gravity-driven hydraulic return mechanisms are covered in scratch-resistant, matte injection-molded PP with anti-pinch edges. Under-seat storage uses welded cold-drawn steel wire racks, and all connecting hardware receives a durable powder-coated finish. Writing desks are constructed with an E1 grade MDF core and light beige fire-resistant laminate facing for a smooth, stable work surface. Functional design supports extended, comfortable use for occupants. Seats fold upward via a silent, slow-return mechanism that prevents pinching, and the fixed, continuous writing surface mounted to the back of the preceding row provides stable support for writing, laptop use, and placement of training or course materials. A small metal hook under each desk manages charging cables and headphone cords, while the flip-down under-seat rack stores books, bags, and personal items, sitting flush against the seat back when not in use. The fixed installation resists wobble under normal use, and ergonomic seat, armrest, and desk heights reduce user fatigue during long sessions. This seating is suitable for a range of commercial and institutional spaces, including university tiered lecture halls, corporate training auditoriums, government and institutional conference halls, K-12 multi-purpose halls, continuing education classrooms, and permanent exam hall installations. For procurement, teams should note that structural components carry a 5-year warranty, and the durable material construction stands up to regular high-volume use. Each set ships across two cartons, with on-site assembly required, and the fold-up seat design supports flexible space use for assemblies, exams, and extended training sessions. The neutral, formal finish palette aligns with standard public space design requirements, and individual fixed seat divisions support controlled, separated seating for exam environments.
