Mattress toppers serve as an additional surface or cushion to provide extra support to your mattress. However, not all mattress toppers are created equal. Each topper is constructed differently- whether it’s the materials used or the process of how it’s done. In turn, each mattress topper provides specific benefits and cushion that could be completely different from the next. 

We found our top picks for the best high density mattress toppers and what to look for when selecting your own. In this article, we explain how thickness and density are different and why a high-density topper may be the best match for you.

Thickness vs. Density

Many shoppers don’t know the difference between a thick and dense mattress topper. They go hand in hand, but provide different results. 

  • Thickness: Typically, mattress toppers are available in three thickness sizes ranging from two to three to four inches. 
    • A two-inch-thick mattress topper is going to provide the least amount of added cushion to your mattress. If you consider your mattress comfortable but need additional support and softness, then a two-inch-thick model would be perfect. 
    • Three inches of thickness provides medium support and is typically the most popular. It offers a noticeable layer of cushion and starts to provide a contour-like feel for your body while sleeping.
    • A four-inch-thick mattress topper provides an entirely new feel to your mattress. It completely contours to your body, while also providing an evenly firm surface to rest on. It’s the most luxurious of the thickness levels and provides the most additional cushion.
  • Density: Density determines the amount of foam per square foot. Many people think that the density tells you the overall firmness you’ll experience, but having a dense topper does not necessarily mean it will sleep more firm. High-density mattress toppers offer better support and conform closer to your body than low-density toppers. They’re more durable and prevent your body from sinking in too deep. The proper density for each individual varies on weight. Heavier people will need a higher density topper than someone who is lightweight. 
    • Three pounds per cubic feet or less are considered the least dense and most soft. This low-density topper will allow your body to melt right through, so it’s perfect for adding a soft cushion, but not the best option for support. 
    • Four to five pounds per cubic feet is the happy-medium in density. It supports average-sized individuals, while still providing a soft sleeping experience. 

Toppers with a density of six pounds per cubic feet and up are considered high-density. They can be considered the most firm, but it all depends on the weight of the person using it. They’re heavier but the best at conforming to a person’s body shape.


High density mattress toppers are great at providing therapeutic benefits, especially for those that suffer from arthritis or joint pain. This type of topper is the most heavy and supportive, but your weight will determine if this type of topper is the best option for you.
