On cold winter nights, climbing into a bed that has been gently pre-warmed makes all the difference. The Tristar BW-4752 electric underblanket fits a double bed and warms the entire sleeping surface evenly, so you and your partner can drift off without shivering. Place it under your fitted sheet, choose one of three heat levels for each side, and let the polyester fleece add a soft, cosy layer between you and the mattress.

Why choose it

This underblanket gives each sleeper independent control over their side of the bed, so you can enjoy your preferred warmth without compromise. The detachable controllers make it easy to wash the blanket, and the built-in safety features—overheat protection and automatic shut-off—let you relax even if you forget to switch it off. The thin, flexible design stays unobtrusive under your sheet, and the polyester surface feels smooth against the mattress.

Ideal use cases

• Pre-warming a double bed before going to sleep
• Providing extra warmth for elderly people or those who feel the cold
• Reducing heating costs by warming only the bed, not the whole room
• Adding comfort in guest rooms or holiday homes during cooler months
• Soothing tired muscles with gentle, consistent heat

Good to know

The blanket should be laid flat between the mattress and the bottom sheet, with the controllers at the head end. Always remove the controllers before washing and ensure the blanket is completely dry before reconnecting. Not suitable for use with a waterbed or an adjustable bed base. For best results, switch on 30–60 minutes before bedtime, then adjust to a lower setting for the night.
