[0024] The bottom of the connecting block 4 is fixedly mounted with a chassis 2 , the upper end surface of the chassis 2 is fixedly mounted with a sponge pad 3 , and the bottom of the chassis 2 is fixedly mounted with a seat 1 .

[0025] The utility model is provided with a fixing block 21, a groove 11, a threaded rod 12, a slider 13, a U-shaped rod 6, a connecting block 4, a through groove, and a lumbar pillow 7. During use, the designer can drive the slider 13 to move up and down by rotating the threaded rod 12, so as to adjust the height of the lumbar pillow 7. The lumbar pillow 7 can be fixed and adjusted according to the height of the user, which is more convenient to use.

[0026] like Figure 3 As shown, the outer wall of the lumbar pillow 7 is provided with a protective cover 8, and the outer wall of the protective cover 8 is symmetrically fixed with two fixing components.

[0027] By providing a protective cover 8 on the outer wall of the lumbar pillow 7, this design can prevent the lumbar pillow 7 from being contaminated during use. By providing a fixing component, the protective cover 8 can be fixed to the lumbar pillow 7, which is more convenient to use.

[0028] like Figure 3 As shown, the fixing assembly includes two fixing belts 16, the ends of the fixing belts 16 are fixedly installed on the outer wall of the protective cover 8, and a shaped buckle 17 is fixedly installed on the other outer wall of the protective cover 8 at a position corresponding to the fixing belt 16.
