adjustable

This term describes a quality of flexibility and customization. It suggests a mechanical or systemic capacity to be tuned, shifted, or modified without breaking the object. It carries a strong connotation of utility and user-centric design, often appearing in technical specifications for furniture, tools, or software settings. While similar to flexible, adjustable implies a more controlled, deliberate change. A flexible material bends under pressure, but an adjustable component is intentionally moved to a new fixed position to achieve a better fit or performance.
