Abstract

A mattress and method of manufacturing the same are provided that may be used during pregnancy. In particular, a mattress and method of manufacturing the same are provided that include a main body portion. The main body portion may define a top surface, bottom surface, first side surface, second side surface, foot surface, and head surface. The mattress may further define a cutout formed in the top surface. At least one insert may be provided that may be disposed in the cutout of the main body portion, with the at least one insert including a substantially concave surface that may receive a user'"'"'s stomach.

wherein the second insert abuts the plane of the top surface,

wherein the first insert is disposed entirely below the plane of the top surface, and

wherein the plug insert is configured to engage the second upper surface of the second insert.

2. The mattress of claim 1, further comprising a cover surrounding the main body portion, wherein the cover is configured to maintain the at least one insert in the cutout, and wherein the cover comprises an access opening configured to allow the user to access the at least one insert.

3. The mattress of claim 2, wherein the cover is configured to deform along a portion of the cover aligned with the cutout.

4. The mattress of claim 1, wherein the main body portion of the mattress comprises at least a first layer and a second layer;

wherein the first layer of the main body portion is configured to define the top surface of the main body portion;

wherein a first portion of the cutout is defined in the first layer and a second portion of the cutout is defined in the second layer;

wherein the at least one insert comprises a first insert and a second insert;

wherein when the first and second inserts are engaged with the cutout, the second insert engages the first and second layers and the first insert engages the first layer and the second insert.

5. The mattress of claim 4, wherein the second layer of the main body portion is configured to define the bottom surface of the main body portion.

6. The mattress of claim 1, wherein the at least one insert is configured to be replaced with at least one replacement insert;

wherein the at least one replacement insert defines a replacement concave surface; and

wherein the replacement concave surface has a curvature that is different than the concave surface of the at least one insert.

7. The mattress of claim 1, wherein the cutout is defined in the top surface between the first side surface and a centerline extending between the foot surface and the head surface.

8. The mattress of claim 1, wherein the at least one insert comprises a first insert and a second insert;

and wherein the first insert defines a great-circle distance between 1.96 and 3.93 inches.

9. The mattress of claim 1, wherein the at least one insert comprises a second insert;

and wherein the second insert defines a great-circle distance between 10.24 and 11.81 inches.

10. The mattress of claim 1, wherein the at least one insert is configured to be removable, such that the cutout defines a great-circle distance between 11.81 and 13.39 inches.

11. The mattress of claim 1, wherein the first upper surface of the first insert is substantially planar, and wherein the second upper surface of the second insert is concave.

12. The mattress of claim 1, wherein the second lower surface of the second insert defines at least one perpendicular angle, and wherein the second upper surface is concave.

13. A method of manufacturing a mattress for use during pregnancy, the method comprising:

forming a main body portion comprising;

a top surface,

a bottom surface,

a first side surface,

a second side surface,

a foot surface, and

a head surface;

forming a cutout in the top surface of the main body portion; and

forming at least one insert;

wherein the at least one insert is configured to be disposed in the cutout of the main body portion, wherein the at least one insert defines a substantially concave surface configured to receive a user'"'"'s stomach,

wherein the at least one insert comprises an inflatable insert, which inflatable insert is configured to inflate and deflate to change in size,

wherein the at least one insert comprises a first insert and a second insert;

wherein the first insert defines a first upper surface and a first lower surface and the second insert defines a second upper surface and a second lower surface;

wherein the second insert is configured to receive the first insert therein and the first lower surface is configured to be disposed adjacent the second upper surface;

wherein the second insert is configured to be received by the cutout of the main body portion and the second lower surface is configured to engage the cutout; and

wherein the first upper surface and a plane of the top surface of the main body portion are configured to define a first volume and the second upper surface and the plane of the top surface of the main body portion are configured to define a second volume, such that the second volume is greater than the first volume; and

wherein the mattress further comprises;

a plug insert having an upper surface and a lower surface;

wherein the lower surface of the plug insert is configured to engage the first upper surface, and

wherein the upper surface of the plug insert is substantially planar, such that the upper surface of the plug insert is substantially flush with the lane of the to surface of the main body portion;
