Heated Cushion recommendation, please?

My heated throw is very light no heavier than a normal throw
Have you tried a heated gillet ?

I have a electric heated 12x24" pad from Amazon. It's light weight and flexible to wrap round any area that needs extra warmth. . It has 4 setting timer up to 2 hours and 6 heat settings. I usually have it on my back but if my leg ,arm or neck hurts it wraps to the right shape.

Heated throws aren’t heavy - at least mine isn’t. Have you looked at a good range of them? Lakeland is as good a place as any to start.

I’ve only seen one brand of heated cushions (Stoov) and they are quite expensive - the ones I saw were around £100 each, and you might want to buy covers to match existing cushions on top of that. Admittedly they were advertised on Facebook, and it’s usually possible to shop around for much better prices than on there.
