8-Year-Old 28 ILD Talalay: Can It Lose Support Without Visible Sagging?

I’m hoping to get some advice from those of you with experience with component latex mattresses because I’m trying to determine whether my issue is likely the latex, the coils, or something else before I start replacing parts.

Mattress Configuration

In March 2018, I purchased a queen component mattress from Arizona Premium Mattress consisting of:

  • Leggett & Platt Combi-Zone Pocket Coil
  • 3” Talalay latex (#28 ILD / medium)
  • 3” Talalay latex (#19 ILD / soft)
  • Bamboo/wool zippered cover

Both latex layers are the original Talalay layers from 2018. I also purchased a Leggett and Platt Falcon adjustable base in the same order, and the mattress has only ever been on that base.

For reference, I weigh approximately 200 lbs, and my husband weighs approximately 230 lbs. Mr Ken Hightower had walked me through the components and explained that the 19 ILD layer would need to be replaced periodically because of my weight, but that it was the comfort I needed for my hips and shoulders as a side sleeper.

Background

For the first several years, we absolutely loved this mattress. It was comfortable, supportive, and we slept great.

About six months ago, our lower backs started bothering us, and we felt like the mattress had become too unsupported. We suspected the 3” soft (19 ILD) layer had lost support, so we removed it completely.

Since then, we’ve been sleeping directly on the 3” medium (28 ILD) Talalay over the Combi-Zone coils, and initially that seemed to help.

We’ve also always been diligent about rotating/flipping the components periodically over the years. Most recently, we rotated everything about two weeks ago, but it made no noticeable difference in either of our symptoms.

Current Problem

Over the past month, we’ve developed a new issue.

I now wake up with lower back pain almost every morning. The pain is worst immediately upon waking and gradually improves after I’ve been up and moving around for about 30 minutes.

My husband has also recently begun waking up with lower back pain. It has happened the last couple of mornings and also improves after he’s been up for a while.

Why I’m Wondering About the Mattress

A few weeks ago, we stayed at The Greenbrier hotel. Their mattress felt much more supportive, buoyant, and springy—honestly like mostly coils with very little foam. However, it wasn’t “firm” feeling. Both of us woke up feeling great there, with significantly less back discomfort than we have at home.

That experience made me wonder whether our 8-year-old 3” 28 ILD Talalay layer has simply lost enough resilience that it isn’t supporting us the way it used to, even though there are no visible impressions, sagging, tears, or deterioration.

My Questions

  1. Is it common for an 8-year-old 3” 28 ILD Talalay layer to soften enough to cause symptoms like this, particularly for heavier sleepers?
  2. Would you suspect the Talalay latex before the Combi-Zone coils, or vice versa?
  3. If you were troubleshooting this mattress, would you:
    • replace the 28 ILD Talalay,
    • replace it with a firmer ILD,
    • use a thinner comfort layer,
    • or investigate something else first?
  4. Has anyone experienced Talalay latex that looked perfectly fine but had clearly lost support over time?

I’m trying to diagnose the problem before spending money replacing components. Any thoughts or experiences would be greatly appreciated, especially from anyone familiar with Arizona Premium Mattress or the Combi-Zone coil system.

Thank you!

Hey there cbear08,

You have already done a good job narrowing things down, and you’ve eliminated several of the obvious possibilities.

One thing that often gets overlooked is that latex can lose some of its support and resilience without showing visible body impressions or sagging. A Talalay layer can still look almost new while no longer providing the same pushback it did when it was new. That’s especially true after years of nightly use under higher body weights.

At around eight years old, with sleepers at approximately 200 and 230 pounds, I don’t think it’s unreasonable to suspect the 3-inch 28 ILD Talalay. The 19 ILD layer lasting that long is actually pretty impressive, even though softer latex is usually the first component to wear.

I also wouldn’t completely rule out the Leggett & Platt Combi-Zone coil unit. Pocket coils generally have a long service life, but after eight years they can lose some of their original responsiveness even if they haven’t actually failed. It’s possible that both the latex and the coils have changed enough over time that you’re now noticing the combined effect.

Your experience at The Greenbrier is interesting but not uncommon. You described that mattress as feeling more buoyant and springy rather than simply firmer, and both of you woke up with much less back pain. That makes me think you’re noticing a loss of resilience more than a need for a significantly firmer mattress. Plus sized sleepers need support, not necessarily a firmer mattress, and there is a difference. But I have written about these situations many times. Generally, when someone sleeps away from home, hotel, cruise ship, or some other vacation excursion, almost any mattress can feel better if you wake up without pain, but it does not make it the right mattress for you. It just means it is temporarily better than the one at home,but it can sometimes become a unrealistic situation overall.

Before replacing anything, I would make sure the adjustable base is still lying completely flat and supporting the mattress evenly. If possible, I’d also try the mattress on a solid platform or even on the floor for a night or two just to rule out the foundation.

If the problem stayed the same, my next step would probably be replacing the 3-inch 28 ILD Talalay before replacing the coil unit. It’s more common for latex to gradually lose some of its performance while still looking perfectly normal. If you liked the feel of the Greenbrier mattress, you might also consider whether a slightly firmer Talalay layer, or possibly a thinner comfort layer, would better match what your bodies need today than what worked eight years ago.

I’d also be interested in hearing what @Arizona_Premium thinks. He has worked with this component design for many years and have probably seen enough aging Talalay layers and Combi-Zone coil units to know which component is more likely to be responsible after eight years of regular use. He is your guy for this situation.

Hope this helps, but I think Ken can walk you through this again.
