Claims
1. A mattress core comprising: a base, the base having an open slot A located in an upper portion of the base and an open slot B located in a lower portion of the base, wherein at least one of a horizontal length of slot A and a width of slot A are larger than a horizontal length of slot B and a width of slot B respectively, and the horizontal length of slot B extends for a majority of a length of the base lower portion and the width of slot B extends for a majority of a width of the base lower portion; a one piece inner block located within the base lower portion slot B and shaped as a rectangle block to fill in the majority of the base lower portion slot B with the base lower portion having a remaining space forming a groove within slot B, wherein the groove is shaped as a small rectangle block and accommodates a human arm and shoulder, and the inner block and the groove completely fill up slot B; a one-piece strip-shaped inner block located within the base lower portion groove wherein the base lower portion is completely filled in by said inner block and strip-shaped inner block; and a cover plate complementary to the base upper portion slot A to completely fill in the base upper portion slot A.
2. The mattress core of claim 1 wherein the inner block is a replaceable inner block comprised of at least one of sponge, spring, and palm.
3. The mattress core of claim 1 wherein the strip-shaped inner block is comprised of compressible material.
4. The mattress core of claim 1 wherein the cover plate is complementary to slot A, and the inner block in slot B contacts the strip-shaped inner block and the combination of the inner block and the strip-shaped inner block is complementary to slot B.
5. The mattress core of claim 1 wherein one of the horizontal length of slot A and the width of slot A is equal to the horizontal length of slot B and the width of slot B respectively.

DETAILED DESCRIPTION
(7) FIG. 1-5 shows two preferred embodiments of a mattress core with replaceable inner blocks. It include a base 6, a slot A 4 is located in the upper portion of the base 6, a slot B 5 is located under slot A in the lower portion of the base 6. An inner block 2 is located within the slot B 5. There may be one or more inner blocks 2 in slot B 5. Inner block 2 can be made of sponge, spring, or palm. The space between the inner block 2 and the slot B 5 forms a groove 7. A strip-shaped inner block 3 is placed in the groove 7. The strip-shaped inner block 3 is made of soft material. A cover plate 1 is placed in slot A 4. The cover plate 1 matches and fill up slot A 4. The inner block 2 is in close contact with the strip-shaped inner block 3. Both the inner block 2 and the strip-shaped inner block 3 are located within slot B 5, and the combination of both matches and fill up the space in slot B 5. The horizontal length and width of said slot A are larger or equal to the horizontal length and width of said slot B. The inner block 2 can be made of two half blocks, i.e., first half block 8 and second half block 9. The first block 8 and second block 9 are in close contact with each other. The material for the first half block 8 may be the same or different with the material of the second half block 9. The base 6 can includes two half bases, i.e., first half base 10 and second half base 11.
(8) One preferred embodiment of present inventions are shown in FIGS. 1-3. It includes one inner block 2 used for a full or twin size bed. An inner block 2 is placed in slot B 5 within the base 6. A strip-shaped inner block is then placed into the groove 7, which is formed between the inner block 2 and the slot B 5. Finally a cover plate 1 fills up the slot A 4 within the base 6. It is then ready for use. The strip-shaped inner block 3 is made of soft material. Therefore when someone is laying on his or her side, his or her shoulder and arm can be wholly or partially placed into groove 7. It reduces the pressure against the shoulder and arm. When it is necessary to change the inner block 2, one may simply take out cover plate 1, take out the inner block 102, place a new inner core block 2 into original position, and then put the cover plate 1 back in.
(9) FIGS. 4-5 show yet another preferred embodiment of the present inventions. When bed is a double, queen or king size, the mattress may include a first half base 10 and a second half base 11, which together forms an integrated base. A first half inner block 8 and a second half inner block 9 are placed in slot B 5 formed by first half base 10 and second half base 11. A strip-shaped core block 3 is placed in the groove 7, which is the space between slot B 5 and first half inner block 8 and second half inner block 9. A cover plate 1 is then set in slot A 4, which is formed by first half base 10 and second half base 11. The mattress is then ready for use. Because the strip-shaped inner block 3 is made of soft material when someone is laying on his or her side, his or her shoulder and arm can be wholly or partially placed into groove 7. This reduces the pressure against the shoulder and arm. When a person is laying in another's arms, the holding person's arm can be placed underneath the other's body into the groove. It reduces the pressure on the holding person's arm and shoulder. Further it avoids the feeling or numbness and stiffness for the holding person. It minimize any discomfort that may occur. When it is necessary to change the first half inner block 8 and/or the second half inner block 9, one can simply take out the cover plate 1, take out first half block 8 and/or second half block 9, put a new first half block 8 and/or second half block 9 into their respective original position, and then put the cover plate 1 back in.
(10) Although an exemplary embodiment of the product of the present invention has been illustrated in the accompanied drawings and described in the foregoing detailed description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications, and substitutions without departing from the spirit of the invention as set forth and defined by the following claims. What the present invention does not disclose, is the prior art.
