Title: why is leather so cold.
Post by: paul.fr on 16/05/2007 03:29:55

no matter how warm my home is, leather furniture is always cold. Even at work with the aircon at high the furniture is cold. Why is leather always cold?

Leather has a higher thermal density than air so unless the temperature is the same or greater than body temperature, the leather will feel cool. Once you have sat on your sofa for a little while, it will stop feeling cold since its temperature will have been raised to that of your skin.

Vinyl is even worse (it is real leather and not imitation leather you're talking about, isn't it?) but I don't know whether it's caused by a higher thermal density or greater thermal conductivity.
