The word Firm and Support are often used synonymously when discussing mattresses. However, they are NOT! In the mattress industry Firm refers to a comfort level, like medium or soft. While Support refers to how the mattress will support your body. Therefore, when a mattress wears out over time we typically assume we want a firmer mattress. In reality we want a more supportive mattress. Comfort Level vs Support The mattress industry uses a multitude of words to describe different comfort levels. Some of which include; firm, luxury firm, medium, plush, soft, pillow top, and euro top (added bonus at the end - pillow top and euro top are actually describing an aesthetic). These comfort levels are what is literally on top of the support system in the mattress. In the image above you can see the difference in the comfort layers that are on top of the support system. Most mattresses come in a “triple choice”, meaning three different comfort levels. However, most of the time the support system is the exact same in all three models. Therefore, you aren’t sacrificing support for a specific comfort level. The comfort level is then a personal preference. Pillow Top vs Euro TopThe only difference between a pillow top and euro top is a recessed sew line. The comfort and support are the same in both. Its purpose is merely aesthetic.
