Mattress sagging questions

Hi Scot, I'm glad the site has answered your questions.

Let's see if I can help answer the remaining ones.

The prestige you have is a firm single sided mattress. Unfortunately, but oh so commonly, there is very little discernible information about this mattress online or from Sealy as to whats inside and its components. Its one-sided nature suggests there is only one comfort layer and from the price point, we can assume its entirely synthetic. The 8cm Yanis latex topper you mention is a graphite synthetic blend.

We have a range of detail in our posts about the blends of latex here.

To try and summarise discussing latex is like discussing 'Beer' without specifying whether it be lager, ale or stout you can't really gather any information.

In this case, we know its graphite, which is usually used for an FR layer in more expensive high-quality latex mattresses. Some cheaper mattresses will use this as their 'latex' layer as its the cheapest type of latex. It is also the crumbliest. I could hazard a guess that if you opened the topper and started to rub it would crumble pretty quickly. This is the downside of synthetic cheaper latex but that said its considerably cheaper than high-quality latex! You've found that it has now compressed somewhat, which is a common issue customer come to us with from other mattresses.

Now all foams will compress over their lifetime, just like a spring compresses and softens, like a sofa cushion or car suspension etc. This is natural. The issue is how far it compresses over its lifetime. One thing that is accepted is the higher quality the foam or latex the better the responsiveness (how quickly it comes back to its original position) and how resilient it is. Remembering that Latex in its natural state is used in hundreds of varied applications because it's robust and flexible. The weaker the blend or more synthetic the further away from this benefit you may move. There is no way of ever preventing compression, but you can ensure the material compresses minimally over time. You've been maintaining your mattress which is always the first part of the advice.

1-inch toppers are pretty much useless I'm afraid Scot. They may hold limited short-term value but not the for the long run. This is because all foam will compress over time and once it's compressed there is little left to have any effect. All our toppers are 5cm or greater. We would never guarantee that any mattress would not compress to some degree but what we will say is that we only offer high blends of natural and 100% natural latex mattresses so your really buying the best you can get. To meet your firm preference and latex combination I would recommend the Fusion zero. It gives firm support but has two layers of Dunlop latex, one being a removable topper. I think this is a higher specification of the current mattress you have.

Hope that helps Scot.
