A medical air mattress has a mattress body (30) a lower bedspread (10) and an upper bedspread (50). The mattress body (30) is formed by multiple air cells substantially parallel arranged in a row forming an air cell row. The upper bedspread (50) covers the mattress body (30) and is securely connected to the lower bedspread (10). The mattress further comprises a pumping assembly (70) with a pump (71) and at least a pipeline connecting the pump (71) with the air cells such that inflating and/or deflating of the air cells is controllable selectively.
