Hi JJC,
While price is certainly one of the more important parts of “value” … the “value” of a mattress purchase is what is most important and price is just one of many factors that can affect the “value” of a mattress purchase. There isn’t a “formula” that can be used to assess or “calculate” the value of a mattress because there are so many different variables and criteria involved that can affect the price of a mattress that can each be more or less important to some people and not to others who may have completely different criteria or definitions of “value”. The “value” of a mattress purchase is also relative to how a mattress compares to the other finalists you are considering or to other mattresses that are available to you in your area (or online if you are also considering online options). There are many reasons that a mattress that may be “good value” for one person or in one area of the country may not be good value for someone else that has very different needs and preferences or that lives in a different area.
There is more about the 3 most important parts of the “value” of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists based on suitability, durability, and all the other parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
I don’t know all the specifics of the mattresses you are considering, the size you are looking at, or the other mattresses you are comparing it to but of the top of my head the prices appear to be reasonable in Canada.
I don’t know the prices off the top of my head so you would need to check their websites or call them to find out but the better options or possibilities I’m aware in the Toronto area (subject to making sure that any mattress you are considering meets your criteria and the quality/value guidelines I linkd earlier in this reply) are listed in post #1 here.
There is also a list of the better retailers and manufacturers I’m aware of that ship across Canada (both from the US and from Canada) in post #21 here that may be worth considering and/or that you can use for “value” comparisons as well.
If two mattresses were closely comparable in terms of durability and if I believed that I would be likely to sleep better on a mattress that is $200 more than another mattress then it would be worth it to me but these are decisions that each person will need to make for themselves based on all the parts of their personal value equation that are most important to them.
When you look back on a mattress purchase in a decade or more (assuming that you purchase a good quality and durable mattress) you will remember much more about how well you slept on it and how long you slept well than you will about the price you paid and relatively minor differences in price that have only a small effect on the yearly cost of ownership spread out over the years will be much less important to you.
