Posted this elsewhere but thought I would blog it in case it might help others in this cold winter with our poor joints!
"I have just bought a heated throw from a well known high street and mail order company and its fab! Its about 3ft x 5ft. Brown fleece fabric and its washable too. It covers the whole body. It has 9 heat setting and warms up in minutes. As its a brown fleece it looks fine over a chair in the sitting room and not out of place. This plus a relaxation CD put me "away with the faries" very quickly. Cost about £39 but worth it. Made by Dreamland and called relaxwell luxury heated throw.
and No don't work for them I'm sure there are other manufacturers too if you search on heated throws. Really lovely and warming if you have the time to crash and relax for a bit.
