Mattress Forum

I was wondering if anyone had any recommendations for where to try & buy a latex mattress in Canada (or are there US companies which ship to Canada?).  I'm in Montreal & am looking to invest in a good mattress.  I had a quick test trial of a bed called the Rhythmic NC mattress (by a company called EvenRest) but they don't really provide too much info on their website.  It was comfortable during the few minutes when I was laying down but I'd really like to try some other ones.

Any help/advice/recommendations would be greatly appreciated.

Thanks.
