With thermochromic furniture in your house, you'll always know who has been sitting in your seat!

Thermochromic furniture is an innovative kind of furniture (in this case a table) infused with a special dye that changes color when it's temperature changes. Therefore if you sit down on the bench for a few minutes and the heat from your body reaches the die, the spot where you're touching the bench will change color. Likewise, if you put your palm down on the table it will leave a hand print in the same color. The mark fades later as the temperature returns to normal and the dye reverts to its previous state.

This piece of thermochromic furniture is called ‘Linger a Little Longer’ by Jay Watson.
