A 30-inch coffee table usually refers to a tabletop about 30 inches in diameter. Listing heights vary by design but commonly fall between about 13.78 inches and 19.29 inches, so expect most to sit in the mid-teens to high-teens in height.
Common tabletops include tempered glass, MDF or engineered wood (often with veneers), rattan, and solid wood veneers like mango or acacia. Frames and bases are typically metal or iron, solid wood components, or MDF construction.
Many 30-inch tables offer a lower shelf or two-tier designs—examples include clear glass lower shelves, open shelving for baskets or magazines, and woven rattan lower shelves for extra storage.
All listings indicate adult assembly is required. Some include tools or state “Some Tools Provided,” others say “Tools Provided,” and at least one notes tools are not provided; most include hardware and illustrated instructions.
Tempered glass tops are described as heat-resistant and easy to clean. Several wood or MDF tops are noted as easy to maintain—wipe-clean or damp-cloth surfaces—though specific care instructions vary by finish.
