An inflatable device comprising:

• a top sheet;
• a bottom sheet, wherein the top sheet is connected to the bottom sheet to define a cavity configured to be inflated, wherein the top sheet forms a top wall of the cavity in use, and the bottom sheet forms a bottom wall of the cavity in use;
• a plurality of passages extending from the cavity to an exterior of the device, through the bottom sheet, wherein the plurality of passages are configured to permit air to pass from the cavity to the exterior of the device and to flow between a bottom surface of the device and a supporting surface upon which the device is configured to rest;
• and
• a plurality of gussets connected to the top sheet and the bottom sheet and extending across the cavity, each of the plurality of gussets including a base connected to the bottom sheet and extending along the bottom sheet, and two arms extending from the base across the cavity to the top sheet, wherein the arms are connected to the top sheet,
• wherein at least the base of each gusset is an air-permeable material, and wherein a first gusset of the plurality of gussets is positioned to cover at least one of the passages, such that the air-permeable material of the base of the first gusset is configured to allow air to pass through the base and out through the at least one of the passages to escape to the exterior of the device.
