Warm Nights in Minutes – Thanks to ultra-fast heat up

Immediate relief from chill when climbing into bed, ideal for evenings and particularly cold spells. Fast heat-up reduces the need to preheat a room for comfort.

Personalised Comfort – With three heat settings

Three heat settings let users choose a lower, medium or higher warmth level. Simple control of temperature makes it easy to match personal preference without extra layers.

Sleepers can fine-tune warmth to taste, making the bed comfortable for different preferences. Lower settings help maintain a gentle background warmth while higher settings deliver quicker heat.
