How to Make a Mattress Firmer

A flat and firm mattress guarantees a good night’s sleep. While the mattress you picked out might have been perfect for you originally, your mattress will soften over time. Not only can a too-soft mattress be uncomfortable, but also it can cause back issues. Prevent or fix a mattress that's lost its firmness by following these simple tips.

Preventing a Too-Soft Mattress

Here's how to prevent a too soft mattress.

Step 1 - Control the Temperature

If you can regulate the temperature in your bedroom, you can combat your mattress getting softer faster. The warmer the temperature is in your room, the softer the mattress will get. Colder temperatures make it easier for mattresses to retain their firmness, so keep your room cool.

Step 2 - Provide Adequate Support

If your mattress has inadequate support, it will go soft more quickly. Make sure your mattress has adequate support, like a plywood base, and never simply put the mattress on the floor.

Fixing a Too-Soft Mattress

Here's how to fix a too soft mattress.

Step 1 - Buy a Mattress Topper

A mattress topper is a cushion-like pad that goes on top of your mattress. You can purchase ones in varying prices and qualities. Memory foam is a popular choice. Most toppers come with a strap that can be wound around the corner of the existing mattress so that it doesn’t move. Place a topper on your too-soft mattress to fix the issue without having to invest in a completely new mattress.

Step 2 - Replace the Existing Plywood

Before replacing the plywood under your mattress, check with your manufacturer for their recommendations. Then, if appropriate, purchase some plywood that has the same measurements as the mattress. Make sure the plywood is not treated, and that it has been sanded for even edges and sides. Replace the existing plywood on your mattress with the new one. Use the same type of materials on the new plywood that was used to secure the old plywood.

Step 3 - Replace the Box Spring

Box springs are known for giving in to the wear and tear of daily use. If your box spring is losing functionality or if it's broken, replace it with another quality box spring to restore the original firmness. In addition, this will help raise the height of the mattress, giving you a firmer and flatter surface to sleep on.
