Thanks for considering DLX. Latex is a great product and works well for many people, but not for everyone. For most, latex has a buoyant, resilient feel with a more of an “on” the mattress than “in” it experience.
With our LatexLux, we use 1.5" of high-density (1.8 lb) foam over the 3" latex to help mellow out that latex feel. Giving it a more traditional feel.
As for our comfort guarantee, we ask that you sleep on the mattress for at least 30 nights to allow your body to adjust and the mattress to break in. If you’re still having issues, reach out. We’ll ask a few questions and walk through some in-home tests. If a different layer will help, we’ll send one out at no cost one-time within the first 120 nights.
Keep in mind that the Premier and LatexLux are identical except for the 3" comfort layer. If you’re uncertain, we generally recommend starting with the Premier since it has a more traditional feel. If after 30 nights, you discover you’d prefer latex, you can simply pay the difference between the LatexLux and Premier and we’ll send out the latex layer to convert it within the first 120 nights.
We do sell replacement parts after 120 days, but only to DLX mattress owners. This is off-menu, so you’d need to contact us directly to purchase. Please note that the 3" layer is a universal part, so technically you could “hack” the mattress with a 3" layer from another source if you prefer.
Regarding sleeping warm, our mattresses like any other with a similar design don’t necessarily sleep warmer or cooler by themselves. Coil-based mattresses generally sleep cooler because of airflow beneath the padding. But the amount and density of foam above the coils matter. Higher-density foams trap more heat, and softer mattresses sleep warmer because you’re more enveloped by the materials. That’s why memory foam tends to sleep the warmest. It’s dense and you sink into it, almost like being wrapped in a blanket.
The Premier uses springs and contains no memory foam, which helps with airflow, but it’s not a “cooling mattress.” Cooling technologies are often gimmicks. Phase-change materials do work, but the effect typically lasts 10 minutes to an hour. Gel foam, on the other hand, is largely a gimmick and doesn’t provide real cooling.
It’s also important to note that many factors outside the mattress affect temperature. Bedding plays a huge role. Mattress protectors, sheets, comforters, and blankets all impact heat retention. Personally, I once bought a new comforter for a mattress I’d slept on comfortably for 10 years, and suddenly I began waking up sweating. It wasn’t the mattress. It was the new comforter.
Lighter, more breathable bedding makes a big difference. Cotton is natural and breathable but tends to hold moisture, whereas performance fabrics wick it away similar to wearing a cotton t-shirt vs. a Nike Dri-FIT shirt during exercise. Duvets also trap heat because of their layered design, even without the insert. Add sheets and blankets on top, and you’re essentially wrapped in multiple layers, like wearing three T-shirts instead of one.
Some people even rotate bedding seasonally to match the weather. What you wear to bed matters too, as does what you eat or drink before sleep as these can affect your body’s ability to regulate temperature.
If you’ve optimized bedding and sleep habits but still sleep hot, you may want to consider a product like BedJet, Chilipad, Eight Sleep, or SmartDuvet by Rize Home. These are more expensive, but if temperature regulation is your top priority, they may be worth the investment.
