Help figuring out durability of R&S Mattress sold Brooklyn Bedding for my Personal Value Equation?

Hi phuff,

6" layer of soy based foam (is that the same as polyfoam of some kind?)

Yes … it’s polyfoam that has replaced a small percentage of one of the two main petrochemicals used to make it (the polyol) with a soy oil based alternative. You can read more about “soy based” polyfoam in post #2 here. I would compare it and other “plant based” polyfoams to conventional polyfoam of the same density in terms of durability.

What I’d like to know is what kind of durability can I expect to get out of these mattresses. If they’re both going to last 5 years than I’ll be able to figure out how much I’m spending a year and decide if I like the Bliss that much more per year than the mallory, etc. Or if the coils will last longer than the soy polyfoam as a support core, then that makes the mallory last longer with approximately the same comfort level before we have to replace it, then that might make it significantly cheaper, see?

There isn’t any formula that you can use to assign a number of years that you will sleep well on a mattress because there are so many variables involved including the type of materials, your body type and sleeping style, and where you are inside the “range” of a mattress that is suitable for you in terms of PPP. If you are close to the threshold of a mattress that is too soft for you then even a small amount of foam softening may put you outside the range of a mattress that is suitable for you while if you have plenty of “room” for foam softening before a mattress loses the comfort and/or support that is suitable for you then it will last much longer. There is more in post #4 here and the posts it links to about the many factors that can affect the useful life of a mattress relative to each person.

Depending on your weight and sleeping style … the top 5" - 6" or so of a mattress will be the most important factor in the useful life of a mattress and the support core will have much less to do with durability than the comfort layers. Since the top 4" of both mattresses is latex which is the most durable of all the foam materials they should both last you much longer than 5 years (and double that would be a more reasonable expectation) although I would give the edge to the Bliss which has 6" of latex on top.

The most important part of the “value” of a mattress purchase would be how well it matches your unique needs and preferences in terms of PPP because no matter what the cost or quality of a mattress, if you don’t sleep well on it then it would have little value to you. This is where careful and objective testing using the testing guidelines in the tutorial post is important when you are testing local mattresses.

After suitability … then durability would be the next most important part of the “value” of a mattress purchase but based on your descriptions neither one would have a weak link in the materials (you can see the guidelines I would use in post #4 here).

Finally after suitability and durability, then the other parts of your personal value equation that are most important to you (including the price) would also be a significant part of the “value” of a mattress purchase.
