Abstract
A mattress and a method of adjusting the pressure of a mattress are provided. The method includes a first process of measuring internal pressure before a user lies on a mattress having at least two zones in which cells having a closed inner space filled with fluid are formed, a second process of measuring an increase in the internal pressure of each cell occurring when the user lies on the mattress, and an average pressure adjusting process of adjusting an amount of the fluid introduced into each cell of the mattress based on a pressure variation caused by a difference between the internal pressure detected from each cell in the first process and the internal pressure detected from each cell in the second process.
