The arrangement of the pillow 4 is convenient for a person to lean back or head, thereby improving the use effect of the sofa bed. The first cushion body 1 is rotatably connected to the second cushion body 2 and the third cushion body 3 respectively, and the pillow 4 is rotatably connected to the third cushion body 3, so that the second cushion body 2 and the third cushion body 3 can be folded, and the pillow 4 can be folded at the same time. The thickness of the first cushion body 1, the second cushion body 2, the third cushion body 3 and the pillow 4 are all the same, so as to avoid that the cushion body can be placed stably on the ground when unfolded, so that a person can lie on top of it. A first Velcro 11 is provided on one side and the back side of the outer surface of the first cushion body 1, and a second Velcro 12 is provided on one side and the back side of the outer surface of the third cushion body 3. When the third cushion body 3 is folded to form a backrest, the first Velcro 11 can be attached to the second Velcro 12 to improve the stability of the third cushion body 3.

[0034] See Figures 2-6 A storage groove 6 is provided at the bottom of the third cushion body 3, and two fixing plates 7 are provided in the storage groove 6, and a rotating shaft 8 is provided between the two fixing plates 7. The outer wall of the rotating shaft 8 is sleeved with two rotating rods 9, and one end of the rotating rod 9 is provided with a threaded hole 13, and the internal thread of the threaded hole 13 is connected to a threaded column 14, and one end of the threaded column 14 is installed with a suction cup 10. When the third cushion body 3 is rotated and folded to form a sofa, the user can rotate the rotating rod 9 and the suction cup 10 out from the inside of the storage groove 6 and make the bottom of the suction cup 10 fit the ground, so that the rotating rod 9 can support the third cushion body 3.

[0035] See Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The diameter of the suction cup 10 is smaller than the depth of the storage groove 6. The suction cup 10 and the rotating rod 9 are both located inside the storage groove 6.
