A sleeping and resting apparatus is disclosed that may include a bottom enclosure including a plurality of associated walls defining a first spatial region and an array of compartments positioned within the first spatial region defined by the plurality of walls associated with the bottom enclosure. Each compartment may store a predefined volume of granular material. A top enclosure may include a plurality of associated walls defining a second spatial region and an array of flexible containers positioned within the second spatial region. Each flexible container may store a predefined volume of granular material. At least one temperature controlling element may be positioned in physical proximity with the bottom enclosure to add or remove heat from the granular material stored in at least one compartment of the array of compartments.
