Silentnight Comfort Control Electric Underblanket - Kingsize (144cm x 152cm)

The Silentnight Comfort Control Electric Underblanket is a heating pad designed to be placed directly on your mattress beneath your bottom sheet, providing targeted warmth to your sleeping area. This kingsize model measures 144cm wide by 152cm long, making it suitable for standard UK king-size beds. It functions as an energy-efficient alternative to heating entire rooms, allowing you to pre-warm your bed for enhanced comfort during colder months. The blanket is constructed from soft, durable polyester fabric that is machine washable for easy maintenance. It features a single detachable controller with four distinct heat settings, giving you personalised control over warmth levels. An integrated auto-adjusting temperature sensor monitors bedroom conditions and fine-tunes heat output within your selected setting to maintain consistent comfort and prevent overheating. The blanket heats up within approximately 10 minutes and includes safety features such as overheat protection. Easy-fit elasticated straps help secure it flat to the mattress, which is crucial for safe operation. This underblanket is ideal for those seeking an affordable way to stay warm at night without significantly increasing heating bills. It's particularly suited to individuals who feel the cold or want to create a cosy sleeping environment. The design prioritises safety and convenience, with the controller positioned on the right side when lying on the bed. It comes with a reusable storage bag for off-season organisation. Following manufacturer guidance, it's recommended to turn the blanket off before falling asleep to support natural body temperature regulation.
