The Tall Mixed Storage Bookcase with One Raised-Panel Door and Open Shelves, model TBC-9004001900D4S, is an unbranded floor-standing storage cabinet designed for vertical organization with a balanced display and concealed-storage appearance. Its tall rectangular form is finished in low-sheen taupe lacquer or paint, giving it a restrained modern presence that works with both residential and professional interiors. The left side is occupied by a full-height hinged door, while the right side presents open horizontal shelving, and a full-width lower open cubby extends across the base. A recessed plinth lifts the visual mass and creates a shadow line at floor level. Overall dimensions are 900 mm wide, 400 mm deep, and 1900 mm high. Construction uses 25 mm engineered-wood composite panels for the main carcass and shelves, with matching taupe faces and sealed painted edges in a fine square profile. The back is a 9 mm composite or hardboard panel set into a rear rebate. The 22 mm framed composite door features a central raised field and stepped perimeter moulding, adding traditional cabinet detail within the clean exterior. Two concealed adjustable hinges support the tall door, which swings through a 110-degree arc and carries a 30,000 open-close cycle rating. Hardware remains visually concealed. The four right-hand open shelves are spaced on a 310 mm pitch, making them suited to books, binders, and display pieces, while the enclosed compartment and lower cubby offer mixed storage choices. Each shelf supports a 20 kg static load, the top surface supports 35 kg, and total cabinet static load capacity is 155 kg. Shelf deflection is limited to L/200 over a 600 mm span. The cabinet weighs 78 kg net and should be loaded with the center of gravity below 1200 mm from the floor to maintain stable use. This bookcase is appropriate beside a desk in a home study or office for reference materials, samples, and objects that benefit from both hidden and accessible storage. It also fits living rooms and reception areas where a taupe display cabinet can combine decorative open shelving with concealed storage. Procurement planning should account for the substantial build, assembly requirement, and packaging information provided: the product is supplied flat packed, with a reference assembly time of 40 minutes per set and reference packaging figures of 100 kg gross weight, three cartons, and 0.65 cubic meter volume per set. Shelf and top load limits, door clearance, and the recommended loaded center of gravity should be reviewed before installation and use.
