Mattress Lingo Defined: What is edge support and why do I need it?

You’re shopping for a new mattress and doing research online (smart!) when you see the term edge support pop up. What the heck does that mean?

First, here’s a helpful guide on how to buy a mattress online. Next, let's talk edge support!

What is edge support?

Edge support refers to the amount of support the outside edge of the mattress offers. In mattresses with edge support, the perimeter of coils along the interior edge of the mattress are reinforced to make the edges sturdier. Think of this like the crust of a grilled cheese sandwich (or peanut butter and jelly, if that’s more your taste) that keeps the soft, bouncy bread and cheese middle supported and stable!

Why does mattress edge support matter?

Who cares about sturdy edges? You might! Especially if you don’t have them. Edge support is one of those things in life that you really only notice when it’s not there. You may not think about it when you’re sitting on a mattress, unless that mattress has weak edges. Then, you’ll notice because you’ll feel like you’re collapsing into the mattress or you’ll slide right off the bed!


The Benefits of Edge Support: 

More Mattress

Having a sturdy (not saggy) perimeter means you can comfortably lie on more of the mattress’ surface area. So, if you share your bed with a partner, you’ll both feel like you have more space because the edges offer support. 

Easier to Exit

Sturdy edges also make it easier to get in and out of bed because you can sit comfortably on the edge of the bed—great for older folks, people who struggle with mobility, or anyone who just needs a little extra stability! It’s also handy for people who like to sit on the bed to put on their socks and shoes.

Longer Lifespan

A supportive mattress edge can actually help extend the life of your mattress as a whole because it limits sagging and improves the overall structure.

Snuggle Securely

Proper edge support helps make you feel more secure while sleeping too, which is especially important for heavier people. According to the Sleep Foundation, people who weigh over 230 pounds may prefer stronger edge support to help them feel secure. Edge support acts like a gentle barrier that keeps you in place even if you sleep close to the edge of the bed.

But, don’t all mattresses have some edge support?

Nope! Foam mattresses are made purely of memory foam so they don’t have edge support. Latex mattresses don’t have coils or springs so while still more supportive than foam, they generally don’t have any sort of edge support, unless you spring for an upgrade. 

Standard spring coil mattresses and hybrid mattresses may have added edge support but not all do so make sure you do your research. 

Luckily all Allswell mattresses have added edge support! Plus, if you want a little extra, our Supreme and Cool mattresses offer a reinforced quantum edge that provides even more support and structure. Not sure what we mean by hybrid? Learn more in our complete guide to hybrid mattresses!
