When you spend money on a product like a new mattress, which sometimes ends up costing a lot if you are choosing a high-quality brand, then you expect it to fulfill all your requirements and to provide long and peaceful nights for years.
In the market, however, you may find anything and everything, and without a bit of guidance, you may end up with a bad quality mattress. Among the most important things to consider when purchasing a new one is to be sure that it doesn’t slump in the future. And here we are, to list you the best mattresses that won’t sag and give you some tips to buy the perfect one which will not disappoint you in the future.
Why Do Mattresses Sag?
Firstly, though, we need to understand the root of the problem. Sagging could be the result of many different causes; let’s see together a couple of them.
- Bad materials used. It’s clear to everyone how the quality of the materials and of the final product affect strongly the performance of the latter in the long run. Be careful of how a mattress is advertised: oftentimes we find ourselves with beautiful ads full of nice words but, when we look at it more carefully, we find out it is all a façade.
- The foam is not resistant enough. The foam contained in the mattress is exposed to significant pressure every night for many consecutive nights. Mattresses typically soften over time and give less support precisely because the foam “gives up” a little bit more every night, finally creating this feeling of sagging.
Remember that all mattresses will, eventually, sag. It’s part of their life cycle. However, there are better ones that will stand the test of time much better than others. Here are our top picks.

Things to Consider When Purchasing the Best Mattress That Won’t Sag
Remember that trial is fundamental, as, in the end, the one who will have to be sleeping years on a mattress is you. Apart from reviews and advice, you are the one who has to test and find by themselves if you approve of a certain product. Anyways, here are some of our tips to help you navigate the ocean of mattresses that constantly invade the market.
Mattress Types
There are tons of mattress types, and often the one you choose ends up being a personal decision. However, there are types better than others at providing good, no sag mattresses.
For example, latex is much indicated for the most durable mattress. If the layers are designed well enough, i.e., if they are made with resilient materials, then the latex is able to give you the best comfort while also not wearing out with time.
Hybrid mattresses are also very recommendable: the combination of pocket or traditional springs with modern memory foams and gel layers give the mattress good support as well as providing the customer with a nice texture and feeling of coolness and relief.
Speaking of springs, as mentioned, there are two types of them. The traditional ones are the most popular and widely used worldwide, especially because they are perfect for people on a budget while still giving a decent amount of comfort. However, mattresses like these alone (so not in combination with any type of foam, latex, or gel) may not be enough for maintaining a good quality of sleep throughout the years. With time and use, they might give you some problems, so we don’t recommend it if you are specifically looking for mattresses that don’t sag.
Mattress Firmness and Sleep Positions
Contrary to what we said about types, a mattress firmness or your sleep position should not affect the way the mattress will behave in the future. We mean that a good, high-quality mattress that doesn’t sag should stay like that regardless of the way you sleep or its firmness.
That is because those two elements are purely subjective: you shouldn’t be at a disadvantage just because you are a heavy sleeper or you sleep on your stomach. Therefore, you don’t have to worry about it: if the mattress is good enough (and we can guarantee, the above-mentioned surely are), then it will hold regardless of the firmness you bought it with or your sleeping habits.
The Right Materials
A high or low quality material makes all the difference when considering a mattress that won’t hopefully sag. To make sure the product you are being is of the best quality, or at least decent enough to last more than five years, then a useful tip is to check a manufacturer’s website very carefully. If they are legit, one of the first things you’ll notice is the labels and certifications of quality displayed on the page introducing the mattress.
You can then look those certificates up online, and you’ll have a clear idea of the quality of the mattress you could potentially bring home. If they are important labels, then it is clear the company doesn’t joke around its high standards. One of these certifications is the CertiPUR-USⓇ, which is a must have for all mattresses that want to be at the top as it guarantees basic safety and healthy conditions such as the absence of dangerous chemicals in the materials used. There are many others, though, and not all of them may be legit, so keep an eye on scams and dubious companies.
Mattress Foundations
It is very important to check whether the mattress you have chosen is compatible with the foundation you already have. The vast majority of mattresses that don’t sag are perfect on the most common and popular foundations, including box springs, platforms, or adjustable bases.
If you don’t have the right foundation at home, worry not, as most of the mattresses selling companies also offer the possibilities to buy, alongside your mattress, the optimal foundation as well as pillows or sheets.
Warranty and Sleep Trial
Another key aspect when buying a mattress that won’t sag is the warranty, as well as the sleep trial. We all know by now, one of the biggest problems with mattresses is that often they don’t stand the test of time well. Because of this, it is fundamental to check whether you have enough time to test your bed or not, as well as the possibility to return it as soon as you see signs of sagging.
About sleep trials, of course, the more, the better. There are some mattresses that offer amazing trials lasting even up to 18 months, even though the average is 100 days. When looking for a new mattress, pay attention to such detail and try to buy the one that offers you more time: you can test by yourself the quality of the product, and it shows the company is not afraid of letting you try it for long periods of time. Which is, of course, a very good sign.
About warranties, numbers vary, even though nowadays many companies go for lifetime ones. That is, without a doubt, perfect; however, be careful: not always sagging is considered a good enough reason to return the product, therefore make sure to check that out on the company’s website or directly from the customer support before buying it.
FAQ
Why Is My Mattress Sagging on One Side?
Sagging is the natural result of the material of your mattress being worn out after a long time of use. If it’s sagging just on one side, however, the cause could also be found in the materials used for the design of the mattress: some of them are clearly better than others. We advise you to check with your manufacturer and see if the warranty covers this problem.
How Long Should a Mattress Last Before Sagging?
An average number for an average mattress would be from about 7 to 10 years. Of course, the better the materials and design of a mattress, the more it will last, and vice versa. If yours doesn’t even last seven years, then you should try to understand the cause: if it’s because of the way the mattress is made, then we suggest checking some other manufacturers out.
Can You Fix a Sagging Mattress?
Yes, there are a few possibilities to fix the problem. Among the most common solutions, we have the idea of placing pillows underneath the mattress so that the discomfort won’t be much; otherwise, you could try and flip or turn over your mattress and see if that helps with your sleep. However, these suggestions are temporary and won’t last much: buying a new mattress that doesn’t sag seems to be the best option.
Conclusion
We have seen how hard it is for some mattresses to stand the test of time. In reality, in many cases, it’s not even their fault: the foam they are made of, even if it is of the highest quality possible, will eventually present some problems.
However, if the materials used are top notch, such as those used in the best mattresses that won’t sag presented above, you surely have the possibility to enjoy even decades of optimal sleep without much to worry about. That is because one of the main reasons for sagging comes from the bad quality of the materials. The list we made above gives you a vast choice when it comes to the best of the best, so you can enjoy long nights of sleeping without having to worry about sag ever again.
