Advice for Hybrid Latex/Coil Mattress

[phoenix]

Hi js715,

They don’t actually let you choose your layers, nor do they have an option of down substitute. But you can choose the softness or ILD of the latex. Does the breakdown of materials sound good?

There is some missing information and I’m not sure if the layers and components are listed in order from top to bottom (or bottom to top) but if the polyfoam layers are an inch or less on each side then there would be no obvious weak links in the mattress (although I would still want to know the type and blend of the latex and the more specific details of the design along the lines of post #4 here).

The talalay latex is 4" thick, 2" on each side since it’s double sided. Is that enough thickness of latex to actually feel a difference in the ILD rating? I wanted softer like 25-28. But it doesn’t seem like enough latex to feel a difference.

Yes you would most likely feel a difference between different ILD’s. Both the thickness and firmness of the latex and the type and firmness of the innerspring underneath it will affect the pressure relief of the mattress.

And the coils in the mattress are 13 and 1/2" thick which I think is fairly heavy which is good i think.

You probably mean 13.5 gauge wire which is on the thicker/firmer side but the innerspring won’t normally be the weak link of the mattress anyway so I would evaluate it based on your testing for PPP (including motion separation with both of you on the mattress if you sleep with a partner) rather than on the specs of the spring.

The final question that I had was about the box spring. I really like the feel of an actual box spring with springs but he was saying that it does cause a lot of movement in the mattress. Any thoughts on an actual box spring with springs?

A box spring that is designed to work with an innerspring mattress is generally a good choice and can have a positive effect both on PPP and on the durability of the mattress (it adds some “give” under the mattress and cushions any “shocks” on the springs, border wire, and helicals which can affect their durability) but as he mentioned it can affect motion separation and movement on the mattress. Whether you choose a solid foundation (or a modular grid such as you have) vs a box spring would really be a matter of preference (and can change the feel and performance of the mattress) but it’s important that the manufacturer confirms that your foundation would meet their warranty criteria. The “best” choice for a foundation/box spring with a new mattress is generally the one that the manufacturer recommends, especially if it’s designed to be part of and affect the performance of the “sleeping system”.
