Hi Lisa_mocha,
This would depend entirely on the firmness of each type of latex. A “plush” Dunlop mattress could be much softer than a firm Talalay latex mattress. both types of latex come in a wide range of ILD’s or firmness levels.
I agree with you that this is quite costly but besides the online options you have there are also many lower cost latex mattresses available in the Toronto area as well that would be well worth considering.
There is quite a difference in “feel” between Dunlop and Talalay for most people yes (regardless of which manufacturer uses either in their mattress) and the firmness of each mattress and any other design differences including the thickness of each layer would also make a significant difference in how any mattress feels and performs. You can read a little more about the difference in “feel” between Dunlop and Talalay in post #7 here but your own perceptions will be a much more accurate way of telling which you prefer.
My daughter for example was all set to buy a Talalay latex mattress because it’s my personal preference but I told her to test both and not to go by anyone else’s preferences and when she did she thought I was crazy and much prefers Dunlop which is what she sleeps on.
