I was going to buy a HoMedics shiatsu massage cushion from Argos today at £50 but they were sold out. However while wandering through Lidl for tonight's tea I came across a similar product to the one which my dog killed by chewing through the cable.

I bought two at £15 each and I have to say that they are every bit as effective as my HoMedics massage cushion and they come with a 3 year warranty.
They are excellent at mechanically breaking knots in my back and calves.
