Comes with a cooling contact cover for comfort. - Brand: Uniesleep - Target age: 0-24 months - Cover material: Cooling contact cover - Cushion type: Head cushion - Design: Rabbit ear design Purchase price: Approximately 12,000 yen Usage period: Approximately 1 month Because of its structure, which tends to trap heat, I think it can be used all year round, even though it's a cooling contact type.
