The invention relates to a pad (1), in particular for a mattress in the nursing care and hospital fields, comprising a liquid-tight and elastic lower layer (3) and a liquid-permeable and elastic upper layer (4) disposed on the lower layer (3). The lower layer (3) and the upper layer (4) are enclosed by an outer cover (17), which comprises a liquid-tight outer cover lower part (18) facing the lower layer (3) and a liquid-permeable outer cover upper part (19) facing the upper layer (4). The pad (1) is very comfortable to lie and/or sit on and has excellent breathing properties. In addition, the pad (1) is easy to clean and can be recycled accordingly frequently. In order to improve the reclining comfort and breathing properties of existing mattresses, the pad (1) is easy and cost-effective to retrofit.
The invention relates to a pad (1), in particular for use in the nursing care and hospital fields, comprising an elastic spacer textile (2), which is surrounded by an elastic molded foam body (4), wherein a separating layer (3) is disposed between the molded foam body (4) and the spacer textile (2). By foaming the molded foam body (4) to the spacer textile (2), the pad (1) can be produced in any arbitrary outside contour (S), wherein uncontrolled penetration of the molded foam body (4) into the spacer textile (2) and a related undesirable increase in the compressive strength are voided by the separating layer (3). The pad (1) is thus very comfortable to lie and/or sit on.
The invention relates to a solids filter (4), in particular for a vacuum cleaner or an exhaust gas cleaning system, wherein at least one filter element (18) is implemented for filtering solids (11) from a fluid flow (7) as an interwoven spacer comprising two cover layers (21, 22) disposed transverse to a flow direction (3) and spacing threads (23) running between said layers. The solids filter (4) comprises a long service life together with a high level of filter effectiveness.

MATTRESS, IN PARTICULAR FOR USE IN CARE AND HOSPITAL FACILITIES
The invention relates to a mattress (1), in particular for use in care and hospital facilities, comprising a base layer (2) and a top layer (3) disposed thereupon. The top layer (3) is formed by an elastic knitted material spacer (7) enclosed by a top layer cover (8). The top layer cover (8) has a liquid-permeable top layer cover lower part (9) and a liquid-permeable top layer cover upper part (10). The mattress (1) allows simple and frequent reprocessing.
