I found an answer at the following site, and thought it to be well stated.
http://experts.about.com/q/Piano-Organ-Keyboard-650/piano-13.htm Following the quote from the above referenced site (which advises an adjustable seat) is info about a recommended seat height if a fixed seat is chosen.

Question
Hi Thomas,
What is the proper height of a piano keyboard in relation to the seat?
Thank you,
Randy
Hello Randy! Thank you for the question. There has been much discussion regarding the correct height of the piano bench relative to the key level. Rather than provide you a measurement, the optimum height from the bench to the key level must vary with the individual player. Remember, a piano is a percussion instrument. The idea is to adjust the height of the bench to afford the performer maximum mechanical advantage. With different torso lengths, the optimum bench height can vary considerably. The correct piano posture dictates that the wrists be somewhat horizontal with the arms as the curved fingers rest on the key surfaces. If the elbows are too low relative to the key level, the wrists must flex creating a mechanically inefficient state. Likewise , if the elbows are too high, the wrists must extend also creating a mechanically disadvantaged state...and discomfort If an adjustable bench is not available then like the old adage, “if the shoe don't fit…” either break out the encyclopedias or take a saw to the bench's feet. Gaining maximum mechanical advantage is what it is about. Not some fixed number.
I hope this information is helpful.
Kind regards,
Thomas Britanyak

The information below was found at the following site:
http://ssl.sheetmusic1.com/smssl/piano.chair.html Paul Jansen & Sons (the manufacturer of piano benches for Steinway, Baldwin, Yamaha in the U.S., and other quality instruments) is no longer manufacturing the adjustable piano chair. The labor required for each chair has made the manufacture of an adjustable chair cost-prohibitive.
The Jansen non-adjustable chair is still available, they will continue to make these popular practice/performance chairs.
If you have a bad back (as I do), there is only one possible way to practice for any length of time at the piano: using a piano chair which supports the lower back.
Jansen chairs are constructed of hardwood maple, no assembly required. The Non-Adjustable chair seat slopes toward piano with 19" height in rear and 18" in front. This is also excellent for solo instrumentalists, as the forward slope of the chair top creates correct posture and better comfort.
