When achieving a good night’s sleep, we often focus on factors like mattress firmness, comfort, and overall support.
However, another crucial aspect is often overlooked—mattress edge support.
If you’re in the market for a new mattress and have found yourself wondering about the term “mattress edge support,” you’ve come to the right place.
It refers to the strong edges that provide stable support both in the middle and along the sides.
So, let’s start because when it comes to a good night’s sleep, every inch of your mattress matters.
Mattress Edge Support – What is It?
Mattress edge support refers to the reinforced perimeter of a mattress that provides additional support and stability along the edges.
It ensures that the mattress maintains its shape and firmness, not just in the center but also along the sides.
Unlike the core support system that runs through the center of the mattress, the edge support system focuses specifically on the border area.
Importance of Edge Support for Various Activities:
Let’s discuss a few activities where Mattress Edge Support can prove valuable:
1. Offers Comfortable Seating
Whether putting on your shoes in the morning or reading a book before bed, having reliable edge support is crucial.
“My patient’s ages range from teens to 90s,” says Dr. Miller. “I always want to know about their bed, no matter their age. I ask about sleep quality, sleeping positions, how many pillows they use, and if their bed is supportive. Many of my older patients utilize their beds to put on their pants and shoes, so a supportive mattress edge is a must.”
It provides a stable and supportive surface when you’re seated on the edge of the mattress, preventing it from sinking or giving way.
This can significantly enhance your comfort and reduce the risk of discomfort or strain on your back, hips, and legs.
2. Sleeping Near the Edge:
Many people tend to sleep closer to the edge of the mattress, either out of habit or to accommodate a sleeping partner.
Without proper edge support, you may experience a “roll-off” sensation or feel like you’re about to slide off the bed.
With reinforced edge support, you can sleep with peace of mind, knowing that the mattress will maintain its structural integrity, providing a consistent sleeping surface.
3. Getting in and Out of Bed:
When you’re getting in and out of bed, especially for individuals with limited mobility or seniors, having stable edge support becomes even more important.
It offers a firm boundary that assists with ease of movement and prevents the mattress from collapsing or losing support as you transition on and off the bed.
This added stability can make your daily routine more comfortable and safer.
Considering the variety of sleep activities beyond just lying in the mattress’s center, edge support significantly enhances your overall sleep experience.
It ensures that your mattress remains supportive, stable, and comfortable, regardless of your preferred sleeping position or activities on the bed.
Who Should Care About Edge Support?
Edge Support is important for getting a peaceful and healthy sleep. Here are a few people who can get the most out of this feature.
a. Couples: Couples who share a bed often need ample edge support to utilize the full surface area of the mattress. Strong edge support ensures both partners can sleep comfortably without feeling like they might roll off the edge.
b. Side Sleepers: Side sleepers tend to utilize more of the mattress’s edge space while sleeping. A mattress with good edge support allows side sleepers to maintain proper spinal alignment and reduces the risk of feeling unsupported or sinking excessively when sleeping near the edge.
c. Elderly Individuals: Elderly individuals may benefit from mattresses with enhanced edge support, as they provide stability when getting in and out of bed. The firm edge helps prevent accidental falls and offers a secure surface for sitting.
“As a pelvic health physical therapist, I treat many pregnant women,” says Dr. Jennifer Miller. “We always discuss bed mobility and transferring safely when getting in and out of the bed. A woman’s center of mass changes during pregnancy (moving up and forward) and this can cause balance issues, so having a supportive mattress edge is important for safety.”
d. People with Limited Mobility: Those with limited mobility or physical impairments rely on sturdy edge support to assist them in sitting on the edge of the bed or transitioning from a sitting to a standing position.
e. Active Sleepers: Active sleepers who frequently change positions during the night or move closer to the edge while sleeping require reliable edge support to maintain stability and prevent any feeling of instability or rolling off the bed.
f. Heavy Sleepers: For heavier sleepers, edge support helps distribute their weight more evenly and prevents excessive sinkage.
g. Stomach Sleepers: Stomach sleepers often require firmer support, and edge support can provide the necessary stability for a comfortable sleep experience in this position.
h. Individuals with Smaller Mattress Sizes: Edge support becomes particularly crucial for individuals with smaller mattress sizes, such as twin or twin XL, where the sleeping surface is limited. Strong edge support allows users to maximize the usable area of the mattress. However, it might not be a problem with King or California King mattresses.
i. People Who Sit on the Edge of the Bed: If you frequently use the edge of your bed for activities like sitting, putting on shoes, or reading, good edge support ensures a comfortable and supportive surface. It prevents the mattress from compressing excessively and maintains proper alignment for prolonged sitting.
How Does Edge Support Differ From Overall Mattress Support?
While overall mattress support refers to the foundational support system that runs through the entire mattress, edge support specifically targets the perimeter.
The core support system, which may consist of coils, foam layers, or a combination of both, provides the main support for your body when lying in the center of the mattress.
On the other hand, edge support reinforces the sides of the mattress, ensuring that you receive consistent support and comfort even when you’re near the edge.
The key distinction lies in the fact that edge support is designed to prevent sagging or compression along the mattress borders.
It aims to maintain a consistent sleep surface across the entire mattress, so you don’t experience a noticeable difference in support or feel like you might roll off the bed when you’re closer to the edge.
