How To Use a Mattress Topper Correctly (4 Easy Steps)

To use a mattress topper correctly, fit the topper securely over a mattress and under a mattress protector and fitted sheet.

Mattress toppers are a simple yet powerful addition to your bedroom setup that add extra comfort, durability, and pressure relief.

This guide is for anyone seeking guidance on how to use a mattress topper correctly and use it as it was designed.

Which Way Up Does a Mattress Topper Go?

A mattress topper goes with the plush, textured, quilted, or pillow-top side facing upwards.

If the topper has straps, the strap attachments face downwards so they can fit around the mattress itself.

If the topper has a design featuring a pointy "egg-crate" side, this faces upwards.

The following steps explain how to fit the topper to your mattress properly.

Step By Step: How to Fit a Mattress Topper Properly

To fit a mattress topper, you need to prepare the mattress surface, uncompress the topper, then secure it in place with straps (if it has them) or a fitted sheet.

Here are the required steps in detail.

Step 1 - Prepare the Surface

Remove all bedding, including sheets and pillows, and give your mattress a good vacuuming to remove dust or debris.

Step 2 - Unbox and Uncompress the Topper

First, unbox your new mattress topper. Give it a chance to fully expand if it's been compressed and boxed for shipping. This can take between a few minutes and an hour, depending on the brand and materials.

If you have an organic mattress topper, it contains no chemicals that off-gas, so you can normally use it as soon as it's finished expanding.

If you bought a synthetic memory foam topper, it may contain chemical flame retardants. Leave the topper in a ventilated area for 2-3 days to allow it to off-gas before moving it to your bedroom.

Step 3 - Fit and Secure with Straps and Fitted Sheet

Some mattress toppers have straps or elastic corners to keep them in place, as shown in the example above. These fit underneath your mattress to stop the topper from sliding around.

If yours doesn't have straps, it simply sits on top of your mattress. Place it so the edges and corners are aligned with those of the mattress underneath.

You can then use a fitted sheet over the mattress topper to hold everything together. You may need a slightly bigger fitted sheet than normal, so be sure to get one with deep pockets.

My eco-friendly bedding reviews include some excellent deep-pocketed organic sheet sets that will fit around a mattress and topper.

You should always put your fitted sheet over your mattress topper, regardless of whether your topper has straps.

Step 4 - Redress the Bed

Finally, put the rest of your bedding and pillows back on, and voilà! Your eco-friendly sleep haven is complete.

Those are the basics that will help you get set up quickly. But to fully understand the correct way to use your mattress topper, you first need to know what it is (and isn't) designed to do.

How to Use a Mattress Topper: What it Does and Doesn't Do

Mattress toppers make a mattress more comfortable and help protect your health, posture, and sleep quality when used correctly over a mattress.

They are not designed for waterproofing or to replace a mattress entirely.

What Should a Mattress Topper Be Used For?

A mattress topper is designed to do the following jobs.

• To enhance the overall comfort and support of your existing mattress.
• Reduce mild to moderate sagging
• Change the feel entirely (eg from soft to firm, or firm to soft, etc)
• To make your mattress last longer.
• To improve the comfort of sofa beds, futons, or even an air mattress.

What Shouldn't a Mattress Topper Be Used For?

A mattress topper is not designed to be used for the following purposes.

• For waterproofing or to protect against spills and stains. Although toppers do offer some protection, you really need a waterproof mattress protector if your main aim is to prevent leaks and stains.
• To compensate for a mattress that is so badly damaged or degraded that it is no longer usable.
• To be used in place of a mattress permanently, although it is ok to use just a topper on its own temporarily.

Is it OK to Sleep on Just a Mattress Topper?

It is OK to sleep on just a mattress topper as a short-term measure, but it is not recommended as a permanent solution. Mattress toppers are designed to be used with mattresses, not in isolation.

There are situations when it can be useful, such as when you're traveling, to replace an RV mattress, or need a temporary guest bed in an emergency.

The disadvantages of sleeping on only a mattress topper include the following.

• Does not provide the necessary support for your spine, which could lead to discomfort or even long-term issues with back pain.
• If you plan to put a topper directly on the floor, you may also find that you sleep hotter, as there will be no opportunity for airflow underneath.
• The lack of airflow will also encourage mold and the accumulation of dust mites if used regularly.
• Using a mattress topper without a mattress underneath may invalidate your warranty.

Remember that a mattress topper is designed to enhance the comfort and support of an existing mattress, not to replace it entirely.
