I'm looking for one of those mattress topper things, in the hope of
relieving my bad back. (The mattress I've got is pretty good so don't want
to replace that and in any case we have one of those electronic adjustable
beds so mattresses are quite tricky for it. ) Has anyone noticed anywhere
with any special offers etc? Would quite like one of the memory foam ones
but not sure if it would be flexible enough to move with the bed so am also
looking at the down ones.
