Choosing solid wood for structural parts of cabinets can lead to issues such as warping, especially if the wood is not properly seasoned or if it is exposed to changes in humidity and temperature. Solid wood, being a natural material, has a tendency to expand and contract with moisture content variations. This movement can result in warping, twisting, or cracking, particularly in larger pieces or for components that experience tension and stress.

In contrast, materials such as composite wood and plywood are engineered to minimize these issues. Composite woods often incorporate various wood particles that are bonded with adhesives, allowing for greater stability and resistance to moisture-related problems. Plywood is constructed from multiple layers of wood veneer glued together, which also diminishes the propensity to warp due to the cross-grain orientation of its layers.

While softwoods can warp, their susceptibility often varies depending on the specific type and how well they are processed. For structural parts, materials with better stability characteristics, like composites or plywood, are recommended over solid wood to ensure longevity and maintain the integrity of the cabinetry.
