<p>PROBLEM TO BE SOLVED: To provide a mat for bedding, giving good sleeping comfort, and improved in usability while retaining air permeability.SOLUTION: A mat for bedding is obtained by assembling a large number of filament loops each formed of a curving continuous filament made of elastic synthetic resin, and accommodating a three-dimensional structure net-like body 5 in which the filament loops are mutually connected, in the inside of an outer cover 2. The mat for bedding is provided with an inner cover 4 which has a bag-like shape for accommodating the whole part except one surface of either an installation side surface or a contact side surface of the three-dimensional structure net-like body 5, and has the strength not allowing an edge part of the continuous filament to penetrate thereinto.</p> |
