This freestanding tall office bookcase, model OBC-GS904520follows a traditional design with a clearly defined two-section vertical layout. The upper 1350 mm tall section holds glass-fronted hinged doors framed in cherry wood veneer, while the lower 650 mm tall section features solid wood-veneer doors, elevated on a 60 mm base plinth for a polished, balanced silhouette suited to professional interiors. The bookcase is constructed with an E1 grade MDF core finished with cherry wood veneer and a smooth lacquer coating, with 2mm PVC edge banding protecting all exposed panel edges. Upper doors are fitted with 5mm clear tempered glass set within veneered frames, while the 5mm hardboard back panel sits securely in routed panel grooves for structural stability.

Four independent hinged doors enable unobstructed access to all storage zones. This bookcase is suited for placement behind executive desks to hold reference materials and curated display pieces, or in shared open office document zones to organize archives and frequently accessed resources.
