Each pair of spring 8 has a same size, and a ratio of a length of the supporting spring 5 to a length of the pressure relief spring 6 in each pair of spring 8 varies smoothly along the length direction of the sleeping system 1, thus a smooth curve formed at a joint between the comfortable layer and the supporting layer along the length direction of the sleeping system 1 (referring to FIGS. 2 and 3). Each pair of spring 8 is packaged in an independent bag 7. Each bag 7 is in a same size. That is, in each bag 7, the total length of the pressure relief spring 5 and the supporting spring 6 is same. In at least one embodiment, the total length of the pressure relief spring 5 and the supporting spring 6 can be 20 cm to 40 cm, for example, 25 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm. It is should be understand that, the total length of the pressure relief spring 5 and the supporting spring 6 can be determined according to different requirements.

[0038] The sleeping system 1 can be divided into a plurality of sections corresponding parts of a human body. For example, referring to FIG. 4, the plurality of sections can include a first section 10 corresponding to a head part of the human body, a second section 11 corresponding to a shoulder part of the human body, a third section 12 corresponding to a back part of the human body, a fourth section 13 corresponding to a waist part of the human body, a fifth section 14 corresponding to a haunch part of the human body, a sixth section 15 corresponding to a thigh part of the human body, a seventh section 16 corresponding to a knee part of the human body, an eighth section 17 corresponding to a shank part of the human body, and a ninth section corresponding to an ankle part of the human body. When a human lays on the sleeping system, pressure of different parts of the human body on the sleeping system 1 are different. In order to provide a more comfortable sleeping experience, a ratio of a length of one of the plurality of the pressure relief springs 5 to a length of a corresponding one of the plurality of the supporting springs 6 can be designed based on the pressure of corresponding parts of the human body on the sleeping system.

[0039] In at least one embodiment, in the center of the first section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 can be 11:16; in center of the second section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 can be 7.5:19.5; in the third section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 can be 9.5:17:5; in the fourth section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 can be 11:16; in the fifth section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 14:13; in the sixth section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 can be 8.5:18.5; in the seventh section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 can be 8:19, in the eighth section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 can be 11:16; and in the ninth section, the ration of the length of the pressure relief spring 5 to the length of the supporting spring 6 can be 12:15.

[0040] In at least one embodiment, in order to provide a more comfortable support to the human body, the ration of the length of the supporting spring 6 to the length of the pressure relief spring 5 can be varied gradually and smoothly. For example, for the first section to the second section, the ration of the length of the supporting spring 6 to the length of the pressure relief spring 5 can be varied from 11:16 to 7.5:19.5 gradually and smoothly. Therefore, a smooth curve is formed at a joint between the comfortable layer 3 and the supporting layer 4. In at least one embodiment, the difference of the length of two adjacent pressure relief springs 5 can be less 2 cm, thus keep the length of the pressure relief spring 5 varies smoothly.

[0041] In at least one embodiment, the sleeping system 1 can be divided into a plurality of sections according to a height of a human body. That is, a length of each section along a length direction of the sleeping system 1 can be determined according to a height of a human body. For example, if a person has relatively long legs, a length of sections corresponding to the leg part of the human body can be designed to be relatively long accordingly. Thus, the sleeping system 1 can be designed to Meet the needs of people of different heights. For example, the seeping system 1 can be designed for a human body with a height of 120 cm, 130 cm, 140 cm, 150 cm, 160 cm, 170 cm, 180 cm, 190 cm, or 200 cm.

[0042] In at least one embodiment, in order to provide a more comfortable sleeping experience, a wire diameter of the pressure relief spring 5 is less than that of the supporting spring 6. In at least one embodiment, the wire diameter of the pressure relief spring 5 can be 1.1 mm-1.8 mm, and the wire diameter of the pressure relief spring 6 can be 1.8 mm-2.3 mm.

[0043] Referring to FIG. 5, one of the plurality of pressure relief spring 5 and a corresponding supporting spring 6 is integrally formed. Such design can avoid the noise and spring dislocation due to a bonding structure under long-term friction. The pressure relief spring 5 and the supporting spring 6 are both in the shape of a barrel which is small on both sides and large in the center. Such design can reduce resistance and friction when the spring is forced to contract downward, thereby reducing noise and increasing service time. The one of the plurality of pressure relief spring 5 and a corresponding supporting spring 6 are packaged in an independent bag 7, which can prevent mildew due to damp and prevent invasion of flying. The bag 7 can be made of non-woven fabric which is durable and anti-worn and anti-tear and water-resistant. Adjacent bags 7 are interconnected with each other by hot welt adhesives so as to keep the bags 7 in place and not to move around. In at least one embodiment, the bag 7 can be made of woven material which is durable and anti-worn and anti-tear and water-resistant. The woven fabric can be single woven fabric including PP (polypropylene), PE (polyethylene) woven fabric, or compound woven fabric including PP and PE compound woven fabric, or PP and PET (polyethylene terephthalate) compound fabric.

[0044] Referring back to FIG. 4, in order to protect the sleeping system and provide a perfect support, the sleeping system 1 further includes a bottom layer 100 arranged under the supporting layer 4. The sleeping system 1 further includes two supporting members 102 arranged at two opposite sides of the sleeping system 1.
