Detailed Description of the Invention
[0027] Referring to the drawings and, particularly to Fig. 1, a mattress topper 10, according to one embodiment of this invention, is shown in connection with a bedding or seating product in the form of a mattress 12. As shown in Fig. 1, the mattress 12 has a longitudinal dimension or length L and a transverse dimension or width W. Although the length L is shown as being greater than the width W, they may be identical. As shown in Fig. 1, the combination of mattress topper 10 and mattress 12 has a height H.
[0028] The mattress 12 may be any known mattress and is not intended to be limited to any particular mattress. For example, the mattress 12 may include a spring core or spring assembly or may be entirely foam. The mattress topper 10 of the present invention may be used in connection with any adjustable bed mattress or sofa sleeper mattress also.
[0029] The mattress topper 10 need not be sold with a mattress or other bedding or seating product. The mattress topper 10 may be sold separately and replaced at any desired time. Fig. 2 illustrates one embodiment of mattress topper 10 separated from a mattress 12. As shown in Figs. 2 and 3, the mattress topper 10 comprises a bucket or casing 14 having a bottom 16 and sides 18. As shown in Fig. 4, an upper portion 20 of each bucket side 18 may be turned inwardly at location 22 to a generally horizontal orientation for assembly purposes, as described below.
[0030] As best shown in Figs. 2 and 3, the mattress topper 10 further comprises a pocketed spring assembly 24 inside the bucket or casing 14. As shown in Fig. 2, pocketed spring assembly 24 comprises a plurality of longitudinally extending strings 26 of individually pocketed springs joined together and extending from end-to-end of the mattress topper 10.
Alternatively, the strings of individually pocketed springs may extend transversely or from side-to-side inside the bucket 14 of the mattress topper 10.
As shown in Fig. 3, each string of pocketed springs 16 comprises a row of individual fabric pockets 28, each containing at least one spring 30. Although one pocketed spring assembly is illustrated, any known pocketed spring assembly may be used including the one disclosed in U.S. Patent No.

[0031] As shown in Figs. 2 and 3, mattress topper 10 further comprises a first cushioning layer of polyurethane foam 32 below the pocketed spring assembly 24 inside the bucket or casing 14 immediately above the bottom 16 of the bucket or casing 14. The mattress topper 10 further comprises a second cushioning layer of polyurethane foam 34 above the pocketed spring assembly 24. Each of the cushioning layers of polyurethane foam 32, 34 may be any desired depth. However, in one embodiment, the depth of each cushioning layer of polyurethane foam 32, 34 is one-half inch. As an alternative, any type of foam, including but not limited to memory foam, may be used for one or both of the cushioning layers 32, 34.
[0032] Another component of the mattress topper 10 is a quilted top layer or fiber panel 36. As best shown in Figs. 3 and 4, this quilted fiber panel 36 comprises an outer fabric layer 38 surrounding a fiber interior 40 sewn together along seams 42 which assume any desired pattern.
[0033] As shown in Figs. 2 and 3, mattress topper 10 further comprises a skirt 44 adapted to fit around mattress 12. At its bottom, the skirt 44 has an elastic band 46 adapted to fit underneath mattress 12 so that the skirt 44 stays on top of the mattress 12. As shown in Fig. 3, the skirt 44 extends from a combination seam 48 shown in detail in Fig. 4 downwardly along the sides 50 of the mattress 12 and along the lower surface 52 of the mattress 12.
[0034] Fig. 4 illustrates the details of the combination seam 48 which joins together the elements of the mattress topper 10 and, more particularly, the bucket 14, the skirt 44 and the quilted upper layer 36. As shown in Fig. 4, tape 54 is wrapped around outer edges of the bucket 14, the skirt 44 and the quilted upper layer 36. The combination seam 48 joins together the upper generally horizontally oriented portion 20 of sidewalls 18 of bucket 14 below a bent generally horizontally oriented upper portion 56 of skirt 44 and an outer generally horizontally oriented portion 58 of the quilted top layer or fiber panel 36. The generally horizontally oriented portion 58 of the quilted top layer or fiber panel 36 is located above the generally horizontally oriented upper portion 56 of skirt 44.
[0035] Fig. 4A illustrates the details of another combination seam 48a which may join together the elements of the mattress topper 10 and, more particularly, the bucket 14, the skirt 44 and the quilted upper layer 36. As shown in Fig. 4A, tape 54 is wrapped around outer edges of the bucket 14, the skirt 44 and the quilted upper layer 36. The combination seam 48a joins together an edge portion 20a of sidewall 18 of bucket 14, an edge portion 56a of skirt 44 and an edge portion 58a of the quilted top layer or fiber panel 36 along with the tape 54. As shown in Fig. 4A, the edge portion 58a of the quilted top layer or fiber panel 36 is located between the edge portion 20a of sidewall 18 of bucket 14 and the edge portion 56a of skirt 44. Once, the edge portion 58a of the quilted top layer 36 and the edge portion 20a of sidewall 18 of bucket 14 and the edge portion 56a of skirt 44 are sewn together with the tape 54 with combination seam 48a, the sidewall 18 of bucket 14 is bent at location 66 downwardly to form an inverted U-shape outside the combination seam 48a.
Similarly, the skirt 44 is bent at location 68 downwardly to form an inverted U-shape outside the combination seam 48a.
Similarly, the skirt 44 is bent at location 68 downwardly to form an inverted U-shape outside the combination seam 48a.
[0036] Figs. 5 and 6 illustrate an alternative embodiment of mattress topper 10a identical to the mattress topper 10, but omitting the lower cushioning layer 32.
[0037] Figs. 7 and 8 illustrate an alternative embodiment of mattress topper 10b identical to the mattress topper 10, but including two additional cushioning layers 60, 62. Each of the cushioning layers 60, 62 comprises fiber batt.

Similarly, cushioning layer 62 is located between the bottom 16 of the casing 14 and the lower foam cushioning layer 32.
[0038] Figs. 9 and 10 illustrate an alternative embodiment of mattress topper 10c identical to the mattress topper 10, but having a non-quilted top layer 64 in place of a quilted top layer. The non-quilted top layer 64 may be made of any desired material. In either of the combination seams 48, 48a shown in Figs. 4 and 4A, a non-quilted top layer 64 may be inserted in place of a quilted top layer.
[0039] Figs. 11 and 12 illustrate an alternative embodiment of mattress topper 10d identical to the mattress topper 10, but having a different pocketed spring assembly 24d in place of pocketed spring assembly 24. The pocketed spring assembly 24d need not be made of strings of individually pocketed springs joined together. Rather the pocketed spring assembly 24d may comprise a blanket of individually pocketed springs, each spring 30d being in a pocket 28d. Although the springs 30d shown in pockets 28d are illustrated as being shorter than the springs 30 in pockets 28 of the mattress topper 10, they may be any desired size. As shown in Fig. 12, pockets 28d comprise upper and lower plies 66, 68, respectively, joined together along intersecting seams 70.
As shown in Fig. 11A, the spaced seams 70 intersect each other at intersections 72 and assume a checkerboard type of pattern. Some of the seams 70 extend transversely or from side-to-side while other seams 70 extend longitudinally or from head-to-foot.
