- Waterproof and easy cleaning: Waterproof, stain-resistant covers simplify upkeep and help prevent moisture buildup that could affect sleep quality.
- Durability and washability: Removable, machine-washable covers and robust frames extend mattress life in busy households.
- Portability and storage: For travel or small spaces, consider foldable designs or mattresses that store conveniently with the crib.
- Multi-stage use: Dual-sided or 3-in-1 mattresses offer extended use from infancy through toddlerhood, maximizing value in tight spaces.
