ELI5: Why do certain objects (let's say a rug) feel warmer than others (the floor) although they should have the same temperature being in the same room.

The rug I put on my floor feels much warmer on my bare feet than the floor. I wondered: Why is it that for example steel feels much colder than other objects in the same environment?

Thermal conductivity. Rugs have poor conductivity  (the ability to transfer heat) compared to wood or metal. Since your body temp is around 37C and room temp ~25C anything conductive that you touch in that environment will immediately start transferring heat away from you in an "effort" to equalise the temperature betwee  the two. Rugs and Styrofoam are good insulators and so don't transfer heat as rapidly.
