It has to-
Be double bed size
Have dual controls
Have timers
Have plenty of temperature settings
Be able heat just the feet end (this is most important, DH has severe nerve damage in his feet which means they're permanently icy cold in winter).
I've googled and looked all over the place. The cheapest I've found one is on Amazon for £55 but I was really hoping to find something cheaper that still suits our requirements, especially now that winter is coming to an end. Am I being delusional hoping for something cheaper that still does everything we want it to or will we just have to suck it up and get the £55 one?
