Abstract

A mattress structure for providing different degrees of relief or support to various body parts of a user or in accordance with different body lengths of the users. The mattress structure includes a principal axis and two or more relief units, distributed in different positions along the principal axis. At least one relief unit provides a degree of relief different from that of another relief unit, to define a relief layer that provides different degrees of relief corresponding to various parts of the body. The relief layer is dividable into two or more relief zones and these zones are divided according to the body parts of the user. The relief units in a relief zone are inter-changeable or re-arrangeable according to needs of the user for accommodating users of different body heights and different lengths of various body parts.

Claims

1-37. -37. (canceled)

38. A mattress structure comprising:

a principal axis; and

a plurality of relief units distributed along the principal axis to form a relief layer, wherein

at least one of the relief units has a reliefability different from that of the other relief unit to define a relief profile with different reliefability along the principal axis,

at least one of the relief units is a main relief unit with a reliefability higher than other relief units,

at least two of the relief units are different in at least one dimension,

the position of the main relief unit relative to the other relief units is changeable by interchanging the position of the relief units relative to one another along the principal axis, such that the position of the main relief unit in the relief layer along the principal axis is adjustable by a unit length in accordance with position of the body part along height of the user for customizing the relief layer,

optionally, the unit length is one inch such that the position of the main relief unit along the principal axis may is adjustable by a unit of one inch, and

optionally, the relief layer is usable with and by placing the relief on a conventional mattress.

39. The mattress structure as claimed in claim 38, wherein

the plurality of relief units includes at least two main relief units'"'"'

optionally, the two main relief units have different relief abilities'"'"'

optionally, the at least one dimension of the relief unit extends parallel to the principal axis of the mattress structure,

the dimension allows interchange of the position of the relief units in the relief layer to adjust relative distance between the two main relief units along the principal axis in unit lengths,

optionally, the unit length is one inch such that the distance between the two main relief units along the principal axis is adjustable by a unit of one inch, and

optionally, the relief layer is usable with and by placing the relief layer on a conventional mattress.

40. The mattress structure as claimed in claim 38, further comprising

a support layer positioned under the relief layer for supplementing the relief unit to support the body of the user;

optionally, a comfort layer positioned on an upper surface of the relief layer to conceal any irregularities of the upper surface;

optionally, the support layer comprises a resilient layer; and

optionally, the resilient layer comprises a plurality of independent springs or a sponge layer.

41. The mattress structure as claimed in claim 38, wherein

the relief layer is dividable into at least two relief zones,

each relief zone corresponds to a body part of the user,

each relief zone includes at least one relief unit, and

optionally, the relief layer is divided into three relief zones, namely, a shoulder relief zone for relieving pressure on the shoulders of a user, a hip relief zone for relieving pressure on a hip of the user, and a leg relief zone for relieving pressure on the legs of the user;

42. The mattress structure as claimed in claim 38, wherein the plurality of relief units are of different softnesses for providing different relief abilities.

43. The mattress structure as claimed in claim 39, wherein the plurality of relief units are of different softnesses for providing different relief abilities.

44. The mattress structure as claimed in claim 41, wherein

each of the shoulder relief zone and the hip relief zone includes a main relief unit,

optionally, the main relief units in the shoulder relief zone and the hip relief zone have different relief abilities and are dimensioned to be interchangeable according to needs of the user, and

optionally, the relief units have different densities for offering different degree of relief.

45. The mattress structure as claimed in claim 40, wherein

the support layer includes at least two support units positioned side-by-side below the relief layer,

optionally, the support units are independently placed,

optionally, the support layer comprises a resilient layer, and

optionally, the resilient layer comprises a plurality of independent springs or a sponge layer.

46. The mattress structure as claimed in claim 38, further comprising a chassis for accommodating the relief units, wherein

optionally, the chassis includes a wall having a height sufficient to overlap at least part of thickness of the relief units for delimiting relative positions of the relief units in the relief layer, and

optionally, the chassis is flexible.

47. The mattress structure as claimed in claim 46, wherein

the chassis is divided into at least two chassis areas which are in positions along the principal axis corresponding to the relief zones,

optionally, the chassis areas contain at least two relief units for holding the relief units together and securing relative positions of the relief units,

optionally, the chassis areas contain at least one support unit and three relief units, and

optionally, the chassis areas contain at least one support unit and five relief units.

48. The mattress structure as claimed in claim 40, wherein

each of the relief layer and the support layer includes an aperture,

the aperture in the support layer is in fluid communication with the aperture in the relief layer for accommodating head of a user and to form an air passage for the user to breath through,

optionally, position of the aperture in the support layer corresponds to position of the aperture in the relief layer in the shoulder relief zone, the aperture of the relief layer is located in a relief unit at a changeable relative position in the relief layer,

optionally, the mattress includes at least one comfort layer placed atop the relief layer to conceal unevenness between the relief units and to form a flat surface, and the comfort layer includes an aperture which is in fluid communication with the aperture in the relief layer and the aperture in the support layer, and

optionally, the mattress further includes a chassis for containing the relief unit, the chassis includes an air permeable structure for establishing air communication with the apertures in the relief layer, the support layer, and the comfort layer to form an air passage.

49. The mattress structure as claimed in claim 44, wherein

each of the relief layer and the support layer includes an aperture,

the aperture in the support layer is in fluid communication with the aperture in the relief layer for accommodating head of a user and to form an air passage for the user to breath through,

optionally, position of the aperture in the support layer corresponds to position of the aperture in the relief layer in the shoulder relief zone, the aperture of the relief layer is located in a relief unit at a changeable relative position in the relief layer,

optionally, the mattress includes at least one comfort layer placed atop the relief layer to conceal unevenness between the relief units and to form a flat surface, the comfort layer including an aperture which is in fluid communication with the aperture in the relief layer and the aperture in the support layer,
