Metals are good heat conductors, so the extra heat is drawn away from the warmer area (your hand) to the cooler areas. Foam is a heat insulator, so the heat won't travel away as fast.
Metal conducts heat better than wood, so when you touch a metal object, it can quickly draw the heat away from your skin, making it feel cooler. Wood is a poor conductor of heat, so it doesn't transfer heat as efficiently, leading to a different sensation when touched.
Metal can conduct heat away from your body (hands) faster than carpet.
foam insulation
The wind can make it feel cooler - wind chill.

In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
Because metal has better thermal conductivity than wood. Thermal conductivity depends of the atomic and molecular structure of the stuff. The air is a poor thermal conductor, but water is better.
The solid metal handlebars are colder because metal is a better conductor of heat/cold than rubber. Its like putting your hand in a 400 degree oven. your hand can stand the air because it is a poor conductor of heat. but you are burned if you touch the metal.
Your body is generally warmer than the spoons. The average human body temperature is around 98.6°F (37°C), while spoons, being made of metal, typically take on the ambient temperature of their surroundings, which is usually cooler than body temperature. Thus, when you touch a spoon, it will feel cooler to your skin.
As long as they wear shades and smoke.
Memory foam is dramatically cooler than latex. I am always never too hot in my bed, but I got mine from www.bedinabox.com (phone no 1-800-588-5720). I was amazed by the price they gave me, a nice and humble company.
Steel is more dense than foam. Steel is a metal with a higher mass per unit volume compared to foam, which is a lightweight, porous material.
