The invention discloses a seat back capable of being hidden. The seat back comprises a rear fixed plate, a front back plate with the upper end hinged to the rear fixed pate, and a supporting plate with the outer end hinged to the inner side of the back plate, wherein at least one notch is formed in the supporting plate, a limiting guide plate is hinged to the interior of each notch, and the other end of each limiting guide plate is hinged to the rear fixed plate. The seat back has the advantages that structure is simple, mechanical stability is high, and the front back plate can be hidden after being put away so that space can be saved; meanwhile, after the front back plate is pulled out, a comfortable back tilt angle and a reasonable seat surface depth which accord with the ergonomic design principle can be formed; when the front back plate is put away, space can be saved, and the seat surface depth which is covered when the front back plate is pulled out can be released so that the seat surface can be wide enough to serve as a bed.
