Rapid warmth – thanks to four heat settings and ultra-fast heat up

New and improved heat-settings and an easy-to-use digital controller allow chosen temperatures to be reached quickly for a faster warm-up.

Warmth arrives within minutes, letting users choose a comfortable setting to avoid overheating.

Even, safer heat distribution – with pinsonic channels that secure wiring

Pinsonic channels hold the internal wires in place so heat disperses evenly across the underblanket and wires are prevented from tangling.

Consistent heat across the sleeping surface reduces hot spots while improving operational safety.

Simple fit and care – with elasticated straps and a detachable controller

Easy-fit elasticated straps secure the underblanket to the mattress and the cable/controller detaches so the cover can be washed.

Straps keep the underblanket flat and secure while machine washing restores freshness and hygiene after repeated use.
