Silentnight Comfort Dual Control Electric Underblanket - King Size (150x160cm)

Silentnight Comfort Dual Control Electric Underblanket - King Size (150x160cm)

The Silentnight Comfort Dual Control Electric Underblanket is designed to provide personalised warmth for couples sharing a bed. This underblanket fits securely beneath your bottom sheet on a standard king size mattress (150cm wide by 160cm long). Its primary function is to pre-warm the sleeping area, offering a cosy retreat during colder months. The design focuses on energy efficiency, with low power consumption making it an economical alternative to heating entire rooms. Key features include dual, detachable controllers that allow each side of the bed to select from three different heat settings independently. This means one person can enjoy a warmer setting while their partner chooses a cooler one. The blanket is constructed from soft, machine-washable polyester and includes easy-fit straps to keep it securely in place on the mattress. Important safety elements are integrated, such as an overheat protection system and BEAB approval, which means its safety has been verified by an independent third party. The manufacturer recommends turning the blanket off before falling asleep to help regulate body temperature for better sleep quality. This product is best suited for couples with differing temperature preferences who want an affordable way to stay warm. It's a practical solution for those looking to reduce overall heating costs by warming just the bed rather than the whole bedroom. The blanket is intended for all-night use on its lowest setting, though many users prefer it for pre-heating. Its low-profile design means it works under most fitted sheets and mattress toppers, including Silentnight's own memory foam products. The included three-year manufacturer's guarantee provides added peace of mind for long-term use.
