The DIWO Modern 3-Bay Mixed Open-Closed Office Storage Bookcase Cabinet (model OBC-3B-DGW-2235) balances functional storage and refined visual presence for commercial workspaces. Its symmetrical three-bay layout combines varied storage access types to create dynamic visual rhythm: the left bay features a full-height vertical-grain walnut wood-veneer sliding door, the middle bay integrates two offset light grey matte hinged doors positioned at upper left and lower right with remaining open shelf space, and the right bay presents four fully open horizontal display shelves. The dark grey melamine-finished carcass, paired with walnut accent panels and matte grey doors, delivers a contemporary two-tone aesthetic suited to professional interiors. All exposed panel edges are finished with color-matched 1mm PVC edge banding for a cohesive, polished look. The unit stands at 2235mm tall, 2235mm wide, and 420mm deep when assembled, with a side panel thickness of 15mm and 3mm thick stapled hardboard back panel. Construction uses P2 grade particleboard for core carcass and shelf components, MDF substrate for accent panels and doors, cold-rolled steel matte black concealed hinges rated for 50000 open-close cycles, and matching hardware for long-term regular use. The left bay’s horizontal sliding door fully conceals stored contents, while middle bay enclosed cabinets offer hidden storage for less frequently accessed items, and open shelves across the middle and right bays support visible display and easy item retrieval. Each shelf supports a distributed static load of 34kg for open shelves and 30kg for enclosed cabinet shelves, with a recommended maximum stored item height of 400mm per shelf to maintain clear sightlines and stable weight distribution. An included wall-mounted anti-tip anchor with 500N pull-out resistance is required for installation to prevent tipping during loading or door operation. This cabinet is ideal for placement behind executive desks to hold files, books, and decorative display pieces, or in open office break-out areas to showcase reading materials, decor, and organize shared office supplies. Procurement teams should note the unit ships across multiple cartons with a total packaged gross weight of 100kg and 0.65 cubic meters of packaging volume per set, requires 40 minutes of assembly time per unit, and must be secured to wall surfaces per safety requirements to meet workplace safety standards.
