Abstract
A mattress includes reduced-firmness materials along a central region thereof in order to mitigate the occurrence of a central ridge following repeated use of the mattress as a sleeping surface. An associated box spring may also, or instead, present a central region with reduced firmness. An adjustable member may be employed to controllably compensate for the development of a central ridge.
Claims23
A mattress comprising:
- a head end;
- a foot end;
- a first side and a second side;
- and
- a center region traversing the mattress from the head end to the foot end, the center region including one or more materials that mitigate the emergence of a center ridge over repeated uses of the mattress.
A box spring configured for use with another box spring to support a mattress, the box spring comprising:
- a head end;
- a foot end;
- an outer side configured to support an edge of a mattress above the box spring;
- and
- an inner side configured to abut a second box spring beneath a center region of the mattress, the inner side having a firmness reduced by about ten percent to about thirty percent relative to the outer side.
A mattress comprising:
- a head end;
- a foot end;
- a first side and a second side;
- and
- a center region traversing the mattress from the head end to the foot end, the center region including one or more materials having a firmness reduced by about ten percent to about thirty percent relative to other regions of the mattress.
A mattress comprising:
- a head end;
- a foot end;
- a first side and a second side;
- a center region separated from the first side and the second side and traversing the mattress from the head end to the foot end;
- and
- a compensation means for reducing a firmness of the center region by about ten percent to about thirty percent relative to other regions of the mattress.
A method for manufacturing a mattress, the method comprising:
- constructing a first region and a second region of one or more materials having a first firmness, the first region and the second region being configured to provide a sleeping surface to one or more users of the mattress;
- and
- constructing a center region between the first region and the second region, the center region being constructed of one or more materials that together have a second firmness less than the first firmness.
A mattress comprising:
- a head end;
- a foot end;
- a first side and a second side;
- and
- a center region traversing the mattress from the head end to the foot end, the center region including one or more adjustable members controllable to adjust the center region in response to an emerging center ridge.
