Abstract: A posture correcting device includes a supporting body, wherein one end of the supporting body is disposed with a front supporting portion, wherein the supporting body is surrounded along one of the ends to form a wearing cavity, wherein an opening is formed between two ends of the supporting body.

Abstract: A rollable pillow includes an elongated pillow body and a constriction assembly. The pillow body has a first end portion, a second end portion and a main body extended between the first end portion and the second end portion. The pillow body is normally extended in a closed position to form an arc-shaped support structure and able to be rolled up and furled to a furled condition to form a furled spiral structure. The constriction assembly includes an extensible constriction member arranged at a first predetermined position of an outer side of the pillow body and a first joining member arranged at a second predetermined position of the outer side of the pillow body such that the constriction member is able to be extended to connect with the first joining member to constrict the pillow body in the furled condition so as to retain the rollable pillow in the furled spiral structure.

Abstract: A rollable pillow includes a pillow body and a constriction assembly. The pillow body has a first end, a second end and a main body having an inner side and an outer side. The constriction assembly includes a first joining member and a second joining member. The rollable pillow has a furled state. In the furled state, starting from the second end and ending with the first end, the outer side of the main body is rolled up inwardly along the inner side to form a laminated furling structure, wherein the first joining member and the second joining member of the constriction assembly are respectively extended in opposite directions along the outer side of the laminated furling structure and joined together to form a closed constricting structure to constrict the laminated furling structure.
