King-size electric underblanket with three heat settings and a detachable controller. Machine-washable fleece construction with elasticated straps for a secure fit.
Fast warm-up – Thanks to an electric underblanket design
Heating elements run beneath the fleece layer to bring sheets up to a comfortable temperature within minutes, controlled by selectable heat levels. The underblanket spreads warmth evenly across the sleeping surface rather than concentrating hot spots.
Sheets warm quickly so falling asleep is easier on cold nights, particularly in bedrooms with little background heating.
Custom overnight comfort – With three heat settings
A detachable controller selects low, medium and high settings, allowing a gentle preheat or a steady overnight temperature. Simple controls make adjustments straightforward without complex menus.
Users can tailor warmth to personal preference, avoiding overheating while maintaining steady comfort through the night.
Hygienic and secure fit – With detachable controller and elasticated straps
Controller detaches so the fleece blanket can be machine washed at 40°C, while elasticated straps hold the pad in place on a king mattress. Care instructions specify the blanket must be fully dry before reconnecting the controller.
Keeping the bedcover fresh is simple, and straps stop the underblanket slipping for uninterrupted sleep.
