Suppose on a summer afternoon, you have two chairs one made of **steel** and other of **wood**. Which one is better to sit on if you prefer colder one, provided they are at the same temperature?  
Would your answer vary if both the chairs are now replaced by a **solid wooden box** and a **steel box filled with water**?  

We may assume that they are at a temperature higher than body temperature.
I understand that we need to apply the concept of heat transfer but unable to decide between conduction and radiation.
