Is an 8-inch Memory Foam Mattress Enough? Does Thickness Matter?

A sound sleep is one of the most intrinsic factors one seeks, and a mattress plays a significant role in putting you down to a soulful sleep. A mattress is your comfort provider, and opting for a memory foam mattress can be an ideal choice. A memory foam mattress absorbs the heat from your body and adjusts itself to procure you extra comfort.

The question that further arises is the thickness of the mattress. You don’t want to suffer discomfort in your back or neck while sleeping, and the thickness of the mattress is one of the diverse parameters that decide the level of comfort the mattress can give you!

Let’s have a keen look at why thickness matters the most when choosing mattresses and the other facets that enhance the vitality and productivity of the mattress.

Does thickness matter in memory foam mattresses?

Yes, thickness does matter in any mattress, and the same is true for a memory foam mattress. The thickness of the mattress is directly linked to luxury and comfort, but this doesn’t imply, high thickness indicates more comfort. So, let’s have a glance at this aspect.

Memory foam mattress comes in a wide range of thicknesses ranging from 3 inches to 14 inches and mattress toppers as well.

While selecting a comfortable memory foam mattress, you need to look after two other aspects that correlate with the mattress’s thickness. The first is the height of the bed from the ground and the thickness of the mattress topper.

Your bed should be at the height of at least 20-25 inches so that your feet can touch the floor and help you get in and out of bed comfortably. Combine the thickness of the mattress along with the height of the bed to know the ideal height.

The next aspect is the mattress’s thickness, which is crucial as this will be the luxury giver to you and your body. A healthy cushion and comfort is the soul of the memory mattress, and you don’t want to compromise with that!

Two layers of the mattress determine its thickness, and these act as a deciding factor to choose the right mattress for your comfort. The two aspects are,

Base Layer

This is the foundation layer that provides judgment about the durability and retention of the mattress. If you are looking for a high-quality integrated memory foam mattress, its base layer must comprise at least half of its total thickness.

The main reason for withering out of the mattress is sagging, and the healthy thickness of the base layer in memory foam mattress prevents sagging, gifting a long life to the mattress. Memory foam mattresses have the base layer of poly-foam or latex foam to deliver extra support.

Comfort Layer

The highest layer of the mattress with a soft cushion-like texture is the comfort layer. Depending on the type of mattress, there can be one or more comfort layers in memory foam mattresses.

The motive of memory foam mattresses is to aid flexible comfort to the body, and thus many mattresses are backed with different layers, which are soft at some specific points and a bit firm at other sections.

The comfort layer must be a minimum of 2 to 3 inches. This allows the mattress to take the desired shape with the cushion. The comfort layer can be of hybrid or latex, or even poly-foam in a memory foam mattress.

The overall thickness of the base and comfort layer decides the total thickness of the mattress. The comfort, durability, solace, and luxury are determined depending on these aspects, and thus thickness matters when choosing a memory foam mattress.

In what thickness memory foam mattresses are available?

When we are talking about the thickness of the memory foam mattresses, their thickness range from 3 inches to 14 inches, along with mattress toppers and every variant of the mattress has its perks. These mattresses are sub-divided into three sections based on their density as

  • Low density: The low-density mattresses are softer and can break up easily.
  • Medium-density: If you are looking for a firmer choice, the medium-density foam mattress can do the work.
  • High density: These mattresses are highly durable and robust and can withstand vigorous use.
