Don’t count on the warranty. Here is an exchange I had with a warranty marshall who happened to do a lot of BeautyRest’s. The mode of operation seems to be that they will use every tool at their disposal to deny warranty claims. The other issue is the lesser dense foams they use, simply do not last as long. I can not say for sure this is planned obsolescence, diliberate use of lower dense foams, or they think their foams are great, and just are not when compared to brands that use higher quality foams.
I will defer to @DLX on this, but will still offer my observation. Since I bought a DLX for my 87 year old mother in law, who had replacement hip and knee surgery (after I had to throw her less than 16 month old BeautyRest into the trash due to the pot hole it developed under her side sleeping hip, an almost 3K waste of time, as she did not consult me prior to buying it)( she had the extended warranty, and Raymour and Flanigan- talk advantange of old lady extended warranty too. The time it would take to get them to act on the warranty… well, I am not going to say it.) DLX had a new split firm/med queen in her house in less than a week. A year and a half later, she still sleeps on the firm side as an 87 year old 170lb woman, the mattress does not have a dent, body impression, or any other compromising defect.
Some mattresses have a dedicated eurotop, usually 2", others do not, but as I hopefully mentioned in my initial post, for most folks there is more than one road to happiness when it comes to finding a comfortable mattress. Foundation, pillow and mattress construction plays a crucial part. What density the foam that is in that pillowtop will matter for longevity. Once those words, density and longevity come out, you dont know if that euphoric week or two feel is going to last for more than 9 months or 29 months. A quality, durable, comfortable mattress is just that, comfortable for the long haul.
When you’re comparing polyfoam and memory foam, it really comes down to the quality of each material. For example, a 2.4 lb high-density polyfoam is going to outperform a 1.5 or 2 lb memory foam by a long shot. It’s not that one type is always better than the other—it’s about how well it’s made and the density used.
The same goes for latex. A well-processed latex layer will usually last longer than most memory foams, unless the mattress has some unique design or construction going on. Memory foam is great for pressure relief and body contouring, but latex can do that too when it’s layered properly. It all depends on how the materials are put together.
Also, don’t take material labels at face value. Polyfoam, for example, comes in a wide range of quality levels. Just seeing “polyfoam” doesn’t tell you much unless you know the specs.
One more thing—this is a personal bias of mine, but I almost forgot to mention it: edge support. You can check out this video here that breaks it down really well. In my experience, edge-to-edge coils offer more consistent support and hold up better over time compared to mattresses that use a foam encasement around the sides. Especially when the whole edge is foam, even high-density foam—those sides just tend to wear out quicker. And if you’re someone like me who sleeps near the edge, that’s a big deal. One part of your body ends up on a 3-5 inch foam perimeter, while the rest is supported by the coils and comfort layers. It throws everything off.
Hopefully this helps.
