THREE LEVEL HEAT CONTROL Slide switch selects low, medium or high warmth, while the 40W element pulses automatically to maintain chosen comfort through the night, costing pennies compared with running central heating. FULL SINGLE SIZE COVERAGE Evenly spaced wiring distributes gentle heat across the entire 90x190cm surface, removing cold shoulder and foot zones so sleepers stay cosy in spare rooms, student digs or holiday caravans. SAFE PEACEFUL SLEEP Sensitive overheat sensor and a fused BS plug cut power immediately if temperatures exceed safe limits, providing reassurance for families, seniors and shift workers who need undisturbed rest. SECURE CORNER STRAPS Four elastic ties anchor the under blanket firmly to the mattress, preventing bunching beneath sheets and keeping warmth even no matter how much you move during the night. MACHINE WASH SIMPLICITY Detach the slide controller then launder the quilted polyester blanket at 30°C, keeping fibres soft, fresh and dust free year after year without expensive dry-cleaning bills.
