The Chillow is a big soothing cool pad. But unlike the ones you may have seen before, it feels pleasantly cool without having to be put in the fridge! How it does that is down to some very clever gel technology which we don't understand, but we can tell you for sure that it works because we use them ourselves.

We all know that lovely feeling of rolling over to a cool patch in bed - but did you know there's even a word for it?

And that's nothing to the relief it gives if you do really need cooling down - sunburn, fever, and especially hot flushes. If you know any Ladies of a Certain Age who seem to be always throwing off their cardies and fanning themselves, this is a gift that they will really appreciate.

The theory is you use the Chillow at night, slipping it in your pillow so you get the benefit without having to think about it...

...but in fact you can use it any time and more or less anywhere. It's less than an inch thick, lightweight, and superbly practical because unlike normal heat or cool bags it takes no preparation whatsoever.
