Hi mjfn,
You seem to be up in lake country where unfortunately as you suspected there aren’t a great deal of alternative choices near you.
I did a search around Kingston, Belleville, and Perterborough to see if there were any local stores that might offer better value or have alternative brands. What I found includes …
http://masterbedroom.ca/. Peterborough, Belleville, Whitby, Pickering. Carries Galaxy and Strata mattresses which are local Toronto manufacturers
http://www.twoheyhome.com/ Peterborough, ON. Kingsdown.
http://www.olympicmattress.ca/ Belleville, ON. Local manufacturer that makes a range of memory foam and innerspring mattresses. I haven’t talked with them so make sure that they will provide you with the foam quality/density specs you need to make an informed choice.
http://mattressmart.ca/ Belleville, Kingston, ON. Endless Comfort which is a local manufacturer based in Vaughan.
http://www.baysidemattress.com/ Belleville, ON. Yorkdale (Dreamstar) which is also a local Toronto manufacturer.
http://diyparksfactory.tripod.com/index.htm Belleville, ON. While they don’t have any all latex mattresses … they do carry a range of mattresses including latex/innerspring mattresses made by Galaxy Bedding (a local Toronto manufacturer) which include some polyfoam in the quilting. They told me they were more than happy to share the specs of any mattress they sell or call the manufacturer if they don’t have it.
http://www.jamesreidfurniture.net/ Kingston, ON. Marshall Mattress which is also a Toronto manufacturer but they are generally in higher budget ranges and I would make sure you can find out all the specs you need to make an informed choice.
If I come across any others, I’ll certainly add them to this list.
A little further away … the list for the Greater Toronto area is in post #1 here.
