Hi mattressnightmare,
Several of the stores in the Toronto list I linked in my last reply (including Dormio and Soma) carry organic Dunlop latex that you could try but they wouldn’t carry SleepEZ mattresses which are only available online or in the Phoenix area.
You can see my comments about both Soma and Dormio in the Toronto list and a forum search on Soma and on Dormio (you can just click the links) will bring up more comments and feedback about both of them as well.
