Underblanket vs throw — which one?
Underblankets go under your sheet and heat the bed before you get in — most efficient for overnight warmth. Heated throws are for sofas and armchairs — think cosy evenings watching TV. Underblankets typically cost £25-60, throws £20-50. Dual-control models let each side of the bed set their own temperature — essential for couples with different preferences.
