How Edge Support Can Improve Your Mattress Comfort & Durability

Understanding the Importance of Edge Support in Mattresses

Are you waking up with discomfort or feeling that your mattress is less durable? If yes, then you might want to explore the possibility of edge support playing a critical role in your overall mattress comfort and durability.

Edge support is a vital component that holds the perimeter of the mattress together by supporting the edges firmly without sagging or sinking. The majority of mattresses are designed with a support core in the center and soft padding on top that enables significant body support and comfort. However, as you move closer to the edges, you may find that the support core is less stable, and there is a loss of comfort and support.

In this blog, we’ll take a closer look at how edge support ( The Surprising Truth About Edge Support and Its Impact on Your Sleep Quality ) can improve your mattress’s comfort and durability.

The Benefits of Edge Support

Multiple benefits come with edge support, including:

1) Better Mattress Durability

Edge support ensures that the mattress retains its shape and doesn’t sag over time. The support core is better protected and holds its shape better, ensuring a longer lifespan for your mattress.

2) Enhanced Body Support

With edge support, your mattress will continue to provide consistent support to your body, even as you move closer to the edge. With reliable edge support, you can sit at the edge of the bed without experiencing sagging or sinking.

3) Increased Sleep Surface

Edge support increases your mattress’s sleep surface, providing full support and comfort throughout the entire bed surface. This means you can utilize all of your bed instead of avoiding the edges.

4) Improved Motion Isolation

With edge support, motion transfer between sleeping partners is also reduced. As a result, if your bed partner starts moving around, you won’t feel any motion disturbances, ensuring a good night’s sleep.

The Different Types of Edge Support

Now you understand the impact that edge support can have on your mattress, it’s time to explore the various types of edge supports available.

1) Foam Encasement Edge Support

The most common type of edge support is foam encasement. This involves reinforcing the bed perimeter with high-density foam, which stabilizes and reinforces the edges. This means your bed can withstand the pressure from sitting and standing, and you won’t experience any sagging or sinking.

2) Coil Edge Support

Coil edge support is often found in innerspring mattresses, which contain steel coils that provide firm support and protect the edges. However, some less expensive innerspring mattresses ( Unveiling the Hidden Benefits of Innerspring Mattresses ) lack edge support altogether, and these may have a shorter lifespan

3) AirEdge

This is a newer technology, AirEdge utilizes inflatable chambers along with foams, providing edge bounce, firmness, and stabilization to the mattress edges.

4) Reinforced Stitching Edge Support

Some mattresses have reinforced stitching along the mattress edges that help keep the edges from giving way or sagging.


Edge support is an essential part of your mattress, and it pays to invest in quality edge support to ensure a more comfortable, durable mattress and a better night’s sleep. While you can find mattresses with less expensive edge support or none at all, paying attention to details can significantly increase the longevity and comfort of your mattress. So, when shopping for a mattress, look for high-quality edge support that ensures consistent comfort and excellent support throughout the bed. By doing so, you can enjoy many nights of restful, comfortable sleep for years to come.
