Durability of softer vs. firmer latex comfort layers

Dear Phoenix, and everyone,

My husband and I are trying to decide between the Parklane Macadam and the Parklane Overton latex mattresses. The Macadam is “firm,” with a 32 ILD support layer and two 32 ILD comfort layers, 100% natural. The Overton is “medium” with a 28 ILD support layer and three 19 ILD comfort layers. The Overton’s comfort layers are also 85% natural and 15% synthetic latex.

I am a side sleeper and the Overton feels better in the store, but we are slightly worried that the softer material will cause the mattress to sag sooner. We made a big mistake in the sleep deprived newborn months with a Sealy Posturepedic from Sleep Country. It sagged horribly within the first few months - well within their 100 day return policy - but between sleep deprivation and the return to work etc. I never got around to returning it. We’ve got about a 2 inch depression in the middle now, after just over one year of use!

So now we’re back in the market and we want this to be a solid long term investment.

I saw the post from another member who heard from a Parklane staff member that they had been having lots of returns on the Macadam from people who thought it was firmer than they remembered from the store. Maybe that is our cue to “go with our gut” and get the Overton, but we would be pretty disappointed if we developed sagging issues anytime soon. With all the plaudits about latex we would hope for at least a good 10 years.

What do you think?

Hi hopeful,

Latex is the most durable of all the foam materials and is much more durable than the polyfoam that is used in the Sealy Posturepedic mattresses in any firmness level.

While it’s true that the firmness of any foam material is a factor in durability (softer is less durable than firmer) … latex is durable enough that even in softer versions it will be a very durable choice and I would choose a latex mattress that your careful testing (hopefully using the testing guidelines in the tutorial post) indicates is the best match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) rather than purposely choosing a mattress that is too firm because of any potential issues with durability. The only time I would choose a firmer mattress is if you really can’t tell the difference between two mattresses that are very close in which case I would choose the one that was slightly firmer but it sounds like there is a clear difference between them in your case.

If a latex mattress you choose is well inside the comfort/support range that is suitable for your body type and sleeping style and isn’t “on the edge” of being too soft when it is new (see post #2 here) then outside of defects in the materials (which would be rare) it would be reasonable to expect that even a softer latex mattress will maintain its comfort and support for 10 years and often longer than that.

It’s always more realistic to think of 10 years as a maximum reasonable expectation for any mattress no matter what the quality of the materials and then treat any additional time after that as “bonus time” because after about 10 years the limiting factor in the useful life of a mattress will often be the changing needs and preferences of the people sleeping on the mattress and even if a mattress is still in good condition after a decade … a mattress that was suitable for you 10 years earlier may not be the best “match” any longer and may need to be replaced. With higher quality materials throughout a mattress or for people whose needs and preferences or physical condition hasn’t changed much over 10 years then “bonus time” or even “extended bonus time” with higher quality/density materials like latex is much more likely than with other types of less durable materials.


Phoenix, thanks a million. Good point about the changing needs and preferences of the people sleeping on the bed after 10 years. I will go test the two mattresses one more time and then make a decision! Will write back to provide a review of whatever we choose once we’ve had it for a while.

Really appreciate your time - thanks for making this site possible.
