Product Ratings

When we rated the products, we took into consideration the most important aspects related to a mattress. Therefore, we ranked our models according to the profile height, sizes available, construction, and so on. In this way, we were able to objectively present you the best firm mattress you can go with. Remember that the quality of your sleep has great significance for a healthy life.

  • Profile Height

    The profile height represents the thickness of a mattress. According to their thickness, the available mattresses are classified as following:

  • Thin: between 5 and 8 inches;
  • Standard: between 8 and 12 inches;
  • Medium-to-Thick: between 12 and 20 inches;
  • Very Thick: above 20 inches;

The most common types of mattresses are the standard ones, being at the same time more expensive than thin beds. This is mainly because they are made of multiple layers that provide the needed support during the night. Very thick models are very expensive and less common and they are usually found in a traditional bedroom decor.
Our models have a height ranging from 11.5 inches (Serta iComfort Blue 300) and 13 inches (Beautyrest Platinum Badger and BodyComfort Select 2000). The other two beds (Allassea Gold Perfect Nite and Zinus Performance Plus) are situated in the middle, having a thickness of 12 inches.

  • Cover

    The main purpose of a cover is to protect the mattress against wear and dirt. Additionally, a superior cover makes the mattress more comfortable, allowing you to sleep better through the night. However, with time the cover may deteriorate but the interior will remain the same. All the models selected by us come with a beautifully designed cover that not only makes them more stylish but also increases their longevity.

  • Layers

    Like most models with a standard thickness, our mattresses are made of a comfort layer and a support layer. While the comfort layer is only a few inches thick, the core or support layer is much thicker. The materials used in manufacturing the mattress are numerous and they differ from one model to another. If we take a closer look at our models, all of them feature a comfort layer made of foam. Of course, there are different technologies of foam that promise superior comfort and support and from our point of view, these mattresses won’t disappoint you. The support layers may be made of foam, inner springs, coils, etc. As you can see, Serta iComfort Blue 300 is the only model in our list that features a foam core. Beautyrest Platinum Badger, Allassea Gold Perfect Nite, and Zinus Performance Plus are made of pocketed coils. Sleep BodyComfort Select 2000 has a support layer of traditional inner springs. According to specialists pocketed coils are better than inner springs as they are individually pocketed in a fabric sleeve. This technology provides a greater support and minimal motion transfer.
