A seat post includes a tube having a stop secured in the middle portion. A pipe is slidably extended through the stop. A rod is secured to the pipe and has a seat cushion secured on top. A spring may bias the pad to engage with a stop of the tube and to cushion the rod. A bolt is threaded to the tube and engaged with the pad for adjusting the spring force of the pad and the spring against the pipe. A barrel is secured on the tube and one or more studs are engaged between the barrel and the rod for preventing the rod from rotating relative to the barrel.
