How To Restore Memory Foam Mattress: A Complete Guide

The worst part? It’s not an aesthetic issue only. It can affect your sleep quality as well. So, this guide will give you everything you need to know on how to restore memory foam mattresses.

Memory foam mattresses are some of the most comfortable to lie on. If you’re having a hard time sleeping, it will surely help. Here is the thing though, as awesome as they are, memory foam mattresses can sag and get body impressions on them.

Know these tips and tricks, and you will be bringing your mattress back to life in no time. One thing is for sure; you will have a better sleep on your newly restored mattress. Say goodbye to those sleepless and uncomfortable nights, and let’s get started.

Why Do Memory Foam Mattresses Sag?

To fully understand the problem, it’s best if we first get into the reasons why your mattress might sag in the first place and why it may need restoring.

There are mainly three reasons why a memory foam mattress might sag. They are:

  • Too much weight
  • Bad foundation
  • No support
  • Too Much Weight

This is one of the most common reasons. The thing with these memory foam mattresses is the thinner they are, the faster they will sag and need restoring. When you sleep on the mattress every night, it will start to sag more and more.

The weight of you lying on them will cause the materials inside to wear. This can be somewhat controlled by getting a thicker mattress.

A typical memory foam mattress will be 10 inches thick. So, if you have thicker ones, that means you’re in pretty good hands, or should we say on pretty good mattresses.

Silly jokes aside, remember that the thinner the mattress, the quicker it will wear out and sag. Also, shared beds mean it’s having to deal with twice the pressure and will wear out even sooner.

First, you will see indentations and somebody marks. All these are fine. It’s the sagging you should worry about.

  • Bad Foundation

A bad foundation means trouble for your mattress. All of them will come with a set of instructions. They should specify what kind of foundation you need and also how much space there should be between the slats as well.

Slats that are more than 3 inches apart will cause damage to your mattress. You will notice that the bed will start to dip, and the foam will be damaged as well.

The idea here is to prevent the mattress from losing its shape. A proper foundation is exactly what helps you achieve that.

Also, the manuals are your best friend here. Make sure you place the mattress on a proper foundation.

  • No Support

No support equals a saggy mattress. It’s as simple as that. New mattresses will come with a few layers, and the bottom-most layer acts as the support layer.

Without this layer, the mattress will sag faster. A lack of support is common in cheap mattresses that have bad support cores.

How To Restore A Memory Foam Mattress?

Alright then, now that you know what the reasons are for the sagging of your mattress, let’s touch on the things you can do to restore it. This section will be helpful if your mattress has already sagged, and you want to give it new life.

We will also touch on some preventive measures you can take to stop your mattress from sagging early. But more on that a bit later.

  • Add More Support

The number one thing you can do is add more support. You can add a bed frame or better foundation when you notice your mattress is sagging. This will help the issue a bit.

You can also use a plywood sheet as support for the mattress. However, we don’t really recommend using solid support or foundation underneath the mattress.

This can lead to mold growth underneath since it restricts air circulation. The best you can do is actually have slats that are 3 inches apart from each other.

Even the manufacturer of the mattress will also probably tell you that this is the best you can do when it comes to proper support and foundation.

  • Get A Mattress Topper

Another very popular and effective fix is using a mattress topper. When you use a thick memory foam mattress topper, it will help even the surface out. This can also help you sleep better in some cases as well.

Since adding a mattress topper evens the surface, you will feel that your body is better supported, and thus you also sleep better. A good quality mattress topper is definitely worth the money.

One thing to note, though, this isn’t a permanent fix. It will also not help you much if the sag is prominent. Mattress toppers are great for dealing with minor sag.

Another similar solution is using a mattress pad. Many people use these terms interchangeably, but there are some differences between the two. Mainly, mattress toppers are thicker and also creates sort of a soft barrier between the mattress and you.

Mattress pads, on the other hand, do not provide as much support as toppers and are made from cotton or polyester.

  • Flip The Mattress

This is more of a last hurrah to the whole sagging thing. As a last resort, you can flip the mattress, and it should help the situation. In fact, regularly flipping the mattress is good to ensure that your mattress doesn’t sag as quickly.

Keep on reading, we will also touch on some preventive measures you can take to stop your mattress from sagging.

Anyway, when you flip the mattress, you will find the sag will go on the other side of the mattress, and you can enjoy a firm sag-free mattress. There is a slight caveat, though.

For this to work as intended, your mattress needs to be dual-sided. You see, not all mattresses are meant to be used in all orientations. Some will have a ‘right’ and ‘wrong’ side.

In the case of some memory foam mattresses, there will be comfort layers at the top of them, and the bottom layers will be for support. You can see then what the problem is when you flip it.

The support layers are usually a lot firmer than the comfort layers. Although some people like a firmer mattress. If that is you, then all the more power to you.

And of course, you can always get a dual-sided mattress, but they aren’t the best quality. So, you need to make a choice here.

Another thing you can do is rotate the mattress instead of flipping it. This way, you don’t put the firmer side of the mattress on top.

How To Prevent Mattress Sag As Much As Possible?

As the old saying goes, prevention is better than cure. This is also true when it comes to mattress sag. While some sag is simply unavoidable, you can mitigate the issue somewhat by taking some preventive steps before it’s too late.

Here is what you can do:

  • Mix Up Your Sleeping Spots

This one will work great if you live alone and don’t share the bed. When you regularly sleep on the same spot of the bed, you certainly are putting more pressure on that particular spot.

Changing up your spot every now and then will take care of this issue and help you get more life out of your mattress.

  • Rotate The Mattress

You can also try rotating the mattress and help it wear slowly. You don’t have to do this too often, though. Once every 3 to 4 months should do. If you want to be extra adamant about it, you flip/rotate it once every month.

This will also do something similar to the first tip. It will take constant pressure off from one particular spot. This time instead of switching up your sleeping spot, you’re just switching up the mattress itself.

As we mentioned earlier, you can also flip the mattress, but the results for that aren’t guaranteed since not all mattresses are made to be dual-sided.

Get A Mattress That Has Great Warranty

You know what, if you buy a high-quality mattress in the first place, you don’t have to deal with many of the problems other cheap mattresses will have you endure.

And the best part is, good mattresses also come with a good warranty. So, getting a mattress that has a good warranty will set you up for success. Keep in mind, though; companies will only honor the warranty only if there are defects and very bad sag.

In most cases, companies will simply replace saggy mattresses that have sag over 1 inch. And it goes without saying that mishandling the mattress won’t help your warranty claim either.

Short Buying Guide

We can’t say buy a good mattress to deal with sag and not give you a buying guide. That just didn’t seem right to us. So, we decided to include a short buying guide to help you choose the right mattress.

When buying a mattress, there are a couple of things you need to look for:

  • Thickness

Make sure your mattress is thick enough for a comfortable sleep. This will also help you with sag. You want a mattress that is 10 inches or thicker. The absolute minimum is 6 inches, but we really don’t recommend this.

  • Firmness

Then you have firmness. Memory foam mattresses might come in three different firmness levels. They are soft, medium, and of course, firm. Firmer mattresses are great for people who are a bit on the heavier side. It also depends on personal preference.

  • Brand

Getting one from a good brand will automatically take care of a lot of things. You will know you are getting a well-reputed product. But make sure not to overspend on features that are just marketing gimmicks.

Frequently Asked Questions

  • How often should I flip my mattress?

Flipping your memory foam mattress is a great way to deal with sag. It will help prevent it, and if you already have some sag, it can deal with that too. Generally, flipping it once every 3 months or so is good. But you can do it every month if you want to be extra adamant.

  • How thick should my memory foam mattress be?

This is a very common question we get from first-time buyers. Getting a thick mattress has many benefits. It helps you prevent sag, and depending on your preference, it can also be more comfortable to sleep on.

Getting above 6 inches at least is recommended. If you can, try to get 10-inch mattresses; those are completely worth it and give you awesome support and sag protection. Keep in mind the thicker the mattress, the more expensive they are.

Memory foam mattresses are an investment in every sense of the word. A high-quality one will easily last you up to 10 years if you take proper care of it.

The great thing is most brands will actually offer you a 10-year warranty as well. So, that is a pretty nifty deal if you ask us.

  • How do I take care of my mattress?

Taking care of your mattress isn’t as difficult as you might think. Just follow the steps we mentioned here, clean it regularly, and avoid eating on the bed. Also, try to keep it away from intense heat sources.

  • Does my mattress need to breathe?

Yes, otherwise, you might see mold growth, and that is just disgusting. The best way to ensure your mattress is breathing is by using a bed frame that has spaces of at least 3 inched between the slats.

Wrapping Up

There you have it. Now you know how to restore memory foam mattresses. While it helps to get a high-quality mattress in the first place, following the steps we mentioned, this guide will help you get the most out of your investment.

Besides, don’t sweat too much. Sag is normal with mattresses. You can still help prevent it or reduce it, though. Happy sleeping!
