A pneumatic cushion for use as a sitting, lying and reclining cushion. The cushion includes a casing made from limited-extensibility material. The casing includes a plurality of webs made from limited-extensibility material, the plurality of webs are adapted to divide a cross-section of the pneumatic cushion into a plurality of chambers and positively connect opposite sides of the casing to each other thereby limiting the cushion's maximum spread at web level. A plurality of gas-tight bladders capable of being pressurized with a pressure fluid are inserted in each of the plurality of chambers created by the plurality of webs and the casing.
