Improvements in mattresses having stiffeners, particularly foam mattresses. Slits are made by at least one perpendicular incision on one side of the padding or foam portion of the mattress, the end of each incision constituting a hinge for the padding portions of the mattress which remain connected together on opposite sides of the incision, and which is opened in the manner of a book. Stiffeners are placed in at least one of the slits, the stiffeners being in the form of stiff laths connected side by side, the laths being slipped into tubular sheaths which are connected to each other and which have profiles and cross-sections corresponding to the laths. A padded and quilted cover is formed on the sides of the mattress with another slit over at least a portion of the periphery and a slide fastener is mounted in this slit.
