Some thermal socks and or sheepskin slippers
Thanks.is it an open draughty location ??
can you move to another wall ??
do you have cold feet when sitting watching the tv?
is this a room in your house ??
a colder annex ??
do you in general suffer from cold extremities ??
the point about watching the tv is in the normal family setting rather than the fairly static at a desk situation ?
