Multi-use apparatus for seating, protective covering, and cushioning

An apparatus, comprising:

• a foldable outer shell comprising:
• a first lateral portion and a second lateral portion separated by a first folding region that extends along a central longitudinal axis of the outer shell;
• and
• a first longitudinal portion and a second longitudinal portion separated by a second folding region that extends perpendicular to the central longitudinal axis;
• a frame disposed within the outer shell;
• a cushioning element disposed within the outer shell;
• a pair of adjustable seat straps coupled to the outer shell, wherein each adjustable seat strap is configured to be selectively transitioned between a coupled configuration and an uncoupled configuration;
• a pair of adjustable case straps coupled to the outer shell, wherein each adjustable case strap is configured to be selectively transitioned between a coupled configuration and an uncoupled configuration;
• and
• a handle positioned in the first folding region,
• wherein the apparatus is configured to be selectively transitioned between a plurality of configurations comprising:
• a mat configuration, in which the outer shell is at least substantially flat;
• a seat configuration, in which the outer shell is folded in the second folding region and in which the pair of adjustable seat straps are in the coupled configuration;
• and
• a firearm cover configuration, in which the outer shell is folded in the first folding region and in the second folding region and in which the pair of adjustable case straps are in the coupled configuration such that the outer shell defines a firearm-receiving cavity configured to receive a firearm, wherein the handle is configured to be gripped by a user when the apparatus is in the firearm cover configuration to lift the apparatus and the firearm.
