A difference of millimeters?

A few months ago I bought a used beach cruiser bicycle from a local bike co-op. I have run into some problems while trying to replace the seat and I could use some advice.
My seat post says 25.0 on it; the internet informs me that a "standard" seat post size is 27.2. The seat post I have looks exactly like this,
designed for a cruiser style seat that attaches with a bolt. This is all well and good except that I don't know how to find a seat that will fit this size, as most cruiser seats I've been looking at on Amazon don't have sizes listed (because it doesn't matter? Does it?)
This all started because the seat I bought from the hardware store a few weeks ago will not securely attach to the post no matter how much tightening I do. I realize this might be a problem with a poorly-designed seat but I am really not sure.
So my question is this: would a higher quality seat tighten down to 25mm? Do I need a different style of seatpost/seat that doesn't attach with a bolt?
The old seat (very rusty and squeaky) fit just fine but unfortunately I am no longer in possession of it.
