Shape-memory materials, such as certain alloys and polymers, recall their original shape after deformation and can return to form with the application of heat or electricity. In the context of furniture, this means objects that can adjust automatically to ergonomic preferences, revert to flat-pack mode for storage, or even “heal” after accidental dents or deformations. The technology promises durability, adaptability, and extended product lifespans, as a single piece can serve multiple purposes throughout its life, transforming with the owner’s needs or whims.
