An air mattress system, comprising: an air mattress configured to self-adjust its own pressure; a user terminal receiving a set value or user information from a user and transmitting the set value or the user information to the air mattress; and a server receiving measurement data from the air mattress to analyze a sleep pattern and sleep quality of a user and transmitting the analyzed sleep pattern and sleep quality to the user terminal, wherein the air mattress is configured such that the air mattress is divided into multiple sections and the pressure is adjusted for each section based on the set value or the user information; and wherein the air mattress includes: an air pocket unit including multiple air pockets each having a hollow portion formed therein and configured to inflate due to air inflow or to deflate due to air outflow; a body portion into which the air pocket unit is inserted; a mattress controller mounted at the body portion and controlling pressure of the air pocket unit; a pressure sensor unit measuring the pressure of the air pocket unit in real time; and an air pump supplying air into the air pockets; characterized in that the air mattress comprises a sleep time measuring unit measuring a sleep time based on a time that the user uses the air mattress; a pressure change amount calculating unit calculating a pressure change amount of the air pocket unit based on a pressure measurement value measured in real time by the pressure sensor unit during the sleep time of the user; and a pressure adjustment amount calculating unit calculating a pressure adjustment amount based on the calculated pressure change amount such that the pressure of the air pocket unit is within an optimum air pocket pressure range ranging from a preset lower limit value to a preset upper limit value that are determined based on the set value and the user information. an air mattress configured to self-adjust its own pressure; a user terminal receiving a set value or user information from a user and transmitting the set value or the user information to the air mattress; and a server receiving measurement data from the air mattress to analyze a sleep pattern and sleep quality of a user and transmitting the analyzed sleep pattern and sleep quality to the user terminal, wherein the air mattress is configured such that the air mattress is divided into multiple sections and the pressure is adjusted for each section based on the set value or the user information; and wherein the air mattress includes: an air pocket unit including multiple air pockets each having a hollow portion formed therein and configured to inflate due to air inflow or to deflate due to air outflow; a body portion into which the air pocket unit is inserted; a mattress controller mounted at the body portion and controlling pressure of the air pocket unit; a pressure sensor unit measuring the pressure of the air pocket unit in real time; and an air pump supplying air into the air pockets; characterized in that the air mattress comprises a sleep time measuring unit measuring a sleep time based on a time that the user uses the air mattress; a pressure change amount calculating unit calculating a pressure change amount of the air pocket unit based on a pressure measurement value measured in real time by the pressure sensor unit during the sleep time of the user; and a pressure adjustment amount calculating unit calculating a pressure adjustment amount based on the calculated pressure change amount such that the pressure of the air pocket unit is within an optimum air pocket pressure range ranging from a preset lower limit value to a preset upper limit value that are determined based on the set value and the user information. an air pocket unit including multiple air pockets each having a hollow portion formed therein and configured to inflate due to air inflow or to deflate due to air outflow; a body portion into which the air pocket unit is inserted; a mattress controller mounted at the body portion and controlling pressure of the air pocket unit; a pressure sensor unit measuring the pressure of the air pocket unit in real time; and an air pump supplying air into the air pockets; characterized in that the air mattress comprises a sleep time measuring unit measuring a sleep time based on a time that the user uses the air mattress; a pressure change amount calculating unit calculating a pressure change amount of the air pocket unit based on a pressure measurement value measured in real time by the pressure sensor unit during the sleep time of the user; and a pressure adjustment amount calculating unit calculating a pressure adjustment amount based on the calculated pressure change amount such that the pressure of the air pocket unit is within an optimum air pocket pressure range ranging from a preset lower limit value to a preset upper limit value that are determined based on the set value and the user information.
