[0002] Traditional pillow cores are usually molded in one piece, and can only use one type of material, either soft or firm. However, users have different needs. Some users prefer firmer materials, while others prefer softer materials. It is impossible to make a pillow core that can be both soft and firm, so improvements are needed. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a comfortable pillow core that balances softness and firmness, and a pillow with the same core.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a comfortable pillow core, the innovation of which is: it includes a left pillow core and a right pillow core, which are interlocked and installed in a Tai Chi-like manner. The left pillow core and the right pillow core are made of sponge materials with different hardness. The left pillow core has a hook-shaped structure and an embedding area is set inside. The right pillow core also has a hook-shaped structure and covers the inside of the left pillow core. A part of the right pillow core is embedded in the embedding area, and the other part is wrapped around the side of the left pillow core.
[0005] Furthermore, the upper surfaces of the left and right pillow cores are spliced together, and the splicing point has a stepped structure.
[0006] Furthermore, the surfaces of the left and right pillow cores are curved.
[0007] Furthermore, the left and right pillow cores are each made of different colors.
[0008] It also includes a pillow whose innovation lies in that it incorporates a pillow core based on any of the above-mentioned options.
[0009] The beneficial effects of this utility model after adopting the above structure are as follows:
[0010] This invention utilizes left and right pillow cores made of sponge materials with different hardness to provide a balance between softness and firmness, catering to the needs of different users and improving comfort. Attached Figure Description

[0013] 1. Left pillow core, 2. Right pillow core, 3. Embedded area. Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Example
[0016] See Figure 1 A comfortable pillow core includes a left pillow core 1 and a right pillow core 2, which are interlocked in a Tai Chi-like manner. The left pillow core 1 and right pillow core 2 are made of sponge materials with different firmness. The left pillow core 1 has a hook-shaped structure with an embedded area 3 inside. The right pillow core also has a hook-shaped structure and covers the inside of the left pillow core, with part of the right pillow core embedded in the embedded area and the other part wrapped around the side of the left pillow core. Specifically, the use of different firmness sponge materials for the left pillow core 1 and right pillow core 2 provides a balance of softness and firmness to suit the needs of different users and improve comfort.
