Inflatable Mat

A casing for receiving a loose insulating material, the casing comprising:

• an inner shell of flexible sheet material;
• an outer shell of flexible sheet material;
• and
• a baffle arrangement located between and connecting the inner and outer shells and comprising a first elongate baffle member and a second elongate baffle member, the first and second baffle members disposed adjacent to one another and formed of flexible sheet material laterally spaced along the inner and outer shells,
• the first and second baffle members, the inner shell and the outer shell defining one or more chambers for receiving the insulating material,
• wherein the first baffle member and the second baffle member are connected to the outer shell along a respective baffle outer edge at an outer connection region and to the inner shell along a respective baffle inner edge at an opposing inner connection region,
• the opposing inner and outer connection regions of the first baffle member being non-linear and following an inverse path from one another in plan view.
