  • the present application relates to an integral, dual-zoned molded pillow composed of high resilience foam (HRF) and viscoelastic foam (VEF) contoured to form selected zones of elasticity; to a separate tri-zoned HRF and VEF mattress pad ; to a reversible mattress having a tri-zoned sleep surface; and to a mattress protector having one or more pouches for accommodating pad inserts to create a multi-zoned sleep surface.
  • the shape and thickness of the HRF and VEF portions are selected to achieve integration of the pillow with the sleep surface to provide optimal support for the entire spinal column of a sleeper, namely upper back, cervical and cranial therapeutic support by the pillow and superior spinal support by the mattress surface.
  • a pillow 10 according to an example
  • the pillow is of a standard shape - typically 21" width, 16" length and 5" inch thickness - with tapered edges 12a and 12b along its length and width respectively.
  • the pillow is formed by a two-stage molding process to produce an upper portion 14 of soft VEF and a lower portion 16 of firm HRF. By proper selection and control of the chemistry and the molding process the body of the pillow emerges from the mold, after curing, with a thin, semi-rigid "skin" 15 intimately sealing portion 14 to portion 16.
  • the HEF inner/lower part 16 appears in vertical cross section as an upwardly concave asymmetrical "paisley” or “dumbell” shape which forms the bottom portion, foot 10a, and crown 10b of pillow 10.
  • the softer VEF outer/upper part 14 of the pillow overlies lower part 16 and embraces and encapsulates the transverse edges thereof, defining the transverse edges 12b of pillow 10.
  • the cranial region of the sleeper subsides into the soft foam and is brought to rest by impinging against the firm HRF.
  • the cranium is effectively and comfortably cradled in the concave "valley" formed between the differently thickened ends of portion 14.
  • the pillow provides two different zones of support for the head and for the upper neck and spine: each zone has differing elasticity based on the thicknesses of HRF and VEF underlying that zone.
  • the PIPTM 5, the polymer foaming chemistry is selected to specify about 5 lb/ft 3 density VEF for the outer core 14 and about 3 lb/ft 3 density HRF for the inner core 16.
  • the total weight of the PIPTM 5 is approximately 5 lbs.
  • the PIPTM 4 the polymer foaming chemistry is selected to specify about 3 lb/ft 3 density VEF for the outer core 14 and about 3 lb/ft 3 density HRF for the inner core 16.
  • the total weight of the PIPTM 4 is approximately 4 lbs.
  • the choice and design of high resilience foam for the inner core may be made with a view to the modulus ("sag factor" ) of the material, i.e. its ability to support weight with an ever-increasing resistance (force of reaction) so that the head does not bottom out. This consideration is of particular importance for supporting the head of a side-sleeper above the surface of the mattress.
  • the density of the VEF and HRF portions may be chosen
  • the pillow may be varied as to its size and/or shape.
  • the pillow has a thickness between 3" and 4", and is referred to as the PIPTM Silhouette.
  • the PIPTM Silhouette retains the same essential structure as the PIPTM described above, but uses proportionally thinner portions of the two foam sections.
  • the pillow comprises a neck pillow 100 for travel having a substantially horseshoe ⁇ like shape.
  • This travel pillow comprises a section of HRF 102 shaped to provide a base of support for the body of the pillow on the user's shoulders and neck, and a crown section of VEF 104 positioned on top of the HRF section 102 and on the inside surfaces facing the user's head to provide padding and support for the user's head as it leans against the top and inside surfaces of the pillow 100.
  • Fig. 8 shows a front cross-sectional view of the neck pillow 100 showing a user's head and shoulders in dashed lines.
  • Fig. 9 shows a top view of the neck pillow 100 showing a user's head and shoulders in dashed lines.
  • the pillow comprises a knee pillow 152 designed for placement between a user's knees and presenting two zones of elastic resistance integrally formed of HRF and VEF portions contoured for optimizing support of the knees and legs of a user.
  • This knee pillow 152 has a substantially rectangular and elongate profile in top view, as seen in Fig. 10, with two raised knee-support mounds 154 for supporting the knees of a user lying on his or her back with the pillow 152 placed under the knees.
  • front cross-sectional view as shown in Fig.

  • Fig. 12 shows the knee pillow 152 being used as a knee support, e.g., for a user lying on his or her side, to provide padding between the user's knees.
  • the pillow 152 is folded in half lengthwise, creating a doubly thick support zone comprising both mounds 154. The user's knees can then be separated by this doubly-thick support zone.
