I tried out the demos at City Mattress for the Prana Sleep line.  The beds felt amazing!  I was in between the firm version and the softer version.  Can anyone suggest a company and know the specs for the Prana line - like the core, etc.   

I also checked out the Sealy Spring collection.  The salesman said that Sealy had made latex matresses for private lines for several year.  He stated that they just purchased a latex factory in South America due to higher public demand - any reference to this?

Thanks!
