Abstract: A vacuum adiabatic body includes: a first plate member defining at least one portion of a wall for a first space; a second plate member defining at least one portion of a wall for a second space having a different temperature from the first space; a sealing part sealing the first plate member and the second plate member to provide a third space that has a temperature between the temperature of the first space and the temperature of the second space and is in a vacuum state; a supporting unit maintaining the third space; a heat resistance unit for decreasing a heat transfer amount between the first plate member and the second plate member; an exhaust port through which a gas in the third space is exhausted; a side frame provided at an edge portion of the third space, the side frame having at least one portion defining a wall for the third space; and a peripheral frame fixed to the side frame to have a part mounted thereto. Accordingly, each part of the vacuum adiabatic body can be mounted without any interference, and an adiabatic effect can be improved.

Abstract: A bed according to an embodiment may include a topper, at least one firmness adjuster provided under the topper, and a bedframe configured to have an adjustable position and to support the firmness adjuster. There may be a plurality of firmness adjusters corresponding to a plurality of areas of the bed, and each firmness adjuster may include a plurality of cushions provided in a cushion case and a drive to adjust the firmness of the plurality of cushions. The drive may change a position of a first spring relative to a second spring in each of the cushions to change a perceived firmness by a user lying on top of the topper and the firmness adjusters. A dryer may be provided under the bedframe to keep the cushions and topper dry.
