Why are some toilet seats so cold?

High specific heat capacity (takes a lot of energy to warm up) OR high heat conductivity (saps heat from your body rapidly).

Your body's perception of heat is actually based on the rate of heat transfer so the second will register as cold even though the material may be at room temperature. This is why metals are cold to the touch.

There you have it.

Ceramics don't have extremely high heat capacity, but their heat conductivity is somewhat high. That's why some thermal pastes for PCs are ceramic based.
