A large, flat pad filled with soft, firm, or resilient material, used as a bed or part of a bed for sleeping or resting on.
Any large, soft, thick pad used for protection, cushioning, or support, such as those used in gymnastics or gardening (e.g., 'air mattress', 'garden mattress'). Figuratively, anything that provides a soft, protective, or supportive base.

Semantic Notes
Typically rectangular and sized to fit a bed frame (single, double, king, etc.). Part of a core semantic set with 'bed', 'pillow', 'duvet'. May be subdivided by type: 'spring', 'memory foam', 'latex', 'air'. Not to be confused with a 'mat', which is thinner and often for the floor.

Common Mistakes
- Misspelling: 'matress' (missing 't').
