Finally I get the chance to pass on this information.

I met a dear gentleman at a trade show from BioFit.   The trade show was very 
slow, so I spent alot of time in his chair.  It was great!.  He also had 
tables of varying heights.  His name is Bob MAson phone # 800597-0246 vm 335.

Mopec is also very ergonomically minded with a chair  they offer.  You can 
email them at MOPEC@aol.com

Then again if you want ergonomic microtomes call Carl Zeiss/Microm at 
800-233-2343
