Comments/Advice from Dr. Vaga (doctorate in piano performance, decades sitting on piano benches):

Overwhelmed with the choices? The top of the line in terms of quality and durability is Jansen - will last a lifetime, we have NO issues or returns with Jansen benches. Made in the U.S., selected hardwoods, hand crafted, unlimited guarantee on quality, I have had several Jansen benches in my studios (university and private studio) over several decades, the quality is outstanding. Jansen sets the highest standard, period.
Poeschl was also good quality - but after 30+ years, Poeschl could not survive the economy, and has gone out of business.
