Bed warmer, electric (Gerrards Cross SL9)

36 x 9 cms (approx). It is NOT oil filled. It's very light in weight. Been in our family for years and works perfectly. You position it just where you want it in the bed (e.g. down where your feet go, if you're a cold feet sufferer!) then plug it in to a normal socket and it heats up in a couple of minutes. You can then move it to different positions to suit you.
