4 Ways to Make Your Mattress Feel Firmer

/ August 3, 2020

So you've had your mattress for a while, and it no longer feels as firm as it used to. That's totally normally—a mattresses's components soften up and conform to your body over time. But while a soft mattress can still be supportive, some people simply prefer the feel of a firm mattress. So what can you do if your mattress feels softer than you'd like it to be?

How to make your mattress firmer

Mattress feeling a little too soft for your liking? There are some easy steps you can take to make your mattress firmer that don't require buying a completely new mattress. Here's what you need to know.

Add a mattress topper

Mattress toppers are most often designed to make your mattress softer, but there are some that do the opposite. A topper is 1-3 inches thick and can be made of memory foam, latex, polyurethane, or filled with down. If you want to make your mattress firmer, a memory foam topper is a good choice because it typically comes in different levels of firmness. A latex topper is also a suitable option. It has a “springy" feel that will give you the firmness you want.

Replace your foundation

Consider the support structure of your mattress. If it's sitting on a box spring, check how old the box spring is. A box spring that's worn out and has loosened springs won't provide the support your mattress needs and could cause your mattress to sag and feel soft. If you can't replace your box spring, try adding a bunkie board between the mattress and box spring for temporary added strength and support. (Always check with your manufacturer first before doing so to ensure this won't void your warranty.)

Flip your mattress

Most mattresses made today are not designed to be flipped, but a small number are. Check with your manufacturer before you flip yours. If yours can be flipped, you may find that one side of the mattress is fimer than the other. For example, our Zenhaven mattress was specifically designed to be flippable and has two different comfort levels: a softer comfort level on one side and a firmer comfort level on the other.

Watch your thermostat

Foam mattresses soften up in high temperatures (as well as in contact with your body) because heat softens the density of the foam. If your room is too hot, turning down the thermostat will help keep it a bit firmer. In fact, it might even help you sleep a little better, as sleeping hot is one of the most common obstacles to getting quality sleep.

Is it time to replace your mattress?

When all of the above fails, consider the age of your mattress. If it's more than seven years old, it might simply be too worn out, and so the best thing to do would be to get a new one.
