Top 10 Best Mattress That Won’t Sag Picks Reviewed (2022)
“As an Amazon Associate I earn from qualifying purchases”
When used regularly, every night, all mattresses soften to some extent. Natural softness does not affect your bed’s pressure-relieving capabilities or comfort level.
However, excessive softening can cause the mattress materials to develop indentations and start sagging quickly. Softening is mainly noticeable in Medium Firm Mattresses and sometimes in Firm or Extra Firm ones.
The average mattress, regardless of firmness, will perform for approximately seven years before a replacement is needed. However, a wide range of factors causes some beds to more likely sag than others.
Sagging occurs typically along the surface of the bed, in the hips, shoulders, and chest areas. When the mattress has excessive sagging, the surface becomes uneven, which leads to aches and pains for sleepers.
A sagging mattress also looks terrible, and it can compromise your health in the long run. A sagging mattress causes stiffness because it throws the spine out of alignment.
You spend many hours of your day sleeping, during which your spine suffers from lying down, all twisted that can affect your blood flow to muscles.
Read on to see our picks for the top 10 best mattresses that do not sag available today. Our selections are based on verified customer and owner experiences, as well as intensive product research and analysis.

The Big Fig is a great option for heavyweight stomach sleepers, heavyweight back sleepers and couples with large body frames.
Note that stomach sleeping is not recommended by chiropractors because the heavier abdominal section usually sinks downwards causing the head and hips of the sleeper to be in an upward facing arch.
This is posture during the night increases tension to gradually build-up and potentially cause pain in the neck and back due to the tightening of the muscles in those areas brought about by the arched spine.
Compared to other mattresses, Big Fig Mattress is backed by a longer-than-average 120-night sleep trial.

BONUS 1: Saatva Classic Hybrid Innerspring Mattress
One of the best mattresses to consider if you're worried about sagging is the Saatva Classic Hybrid Innerspring mattress. This is a luxury mattress that sports many layers of comfort along with an innerspring that will give you the rest you truly deserve.
The innerspring is made out of recycled carbon steel in a dual coil design which prevents any sagging from occurring. The carbon steel is also tempered so that it is even stronger which means that it will truly stand up to the test of time.
The Saatva mattress also uses patented spinal zone technology that comfortably supports your spine and ensures that it is always properly aligned throughout the night.

Side-sleepers usually prefer the softer model because it will contour very well around your shoulders and hips to give you just the right amount of support. People under 120 pounds in weight also prefer this soft version as the others may seem too firm.
The medium-firm option is chosen by the vast majority of Saatva customers as it suits combination, side, back and average weight stomach sleepers. Sleeping on it will resemble a 5-Star luxury hotel bed experience. It is also the preferred choice of couples with different sleep styles.
If you don't like feeling like you are sinking into a mattress, usually back sleepers and stomach sleepers, then the firm option would make it the best firm mattress for you. The extra level of uplifting support is also ideal for those weighing over 250 pounds.
The edges of all these mattresses are designed to prevent sagging, so you don't have to worry about the sides getting saggy over time.
This Saatva mattress has a 3 inch Euro pillow top that adds even more support and comfort. It even has enhanced back support built in under the pillow top to ensure you're always well supported.

BONUS 2: Amerisleep AS3 12" Mattress
The Amerisleep AS3 12" Memory Foam Mattress is considered as one of the most versatile mattresses available in America.
This mattress model features a 3" Bio-Pur® cooling foam layer, 2" Affinity layer, and a 7" Bio-Core™ sag-free support layer. In total, there is a combined 12-Inches of versatile support.
Bio-Pur® is like plant based memory foam but just more responsive and breathable compared to viscoeleastic made traditional memory foam beds. Its breathability means that heat will not be stored and built up inside the mattress to cause you to over-heat as you sleep.
The Bio-Pur® comfort layer contours to the curves of your body and helps to relieve pain from pressure points. This body contouring makes this mattress very popular with side-sleepers as it ensures that your spine is correctly supported throughout the night and will prevent the build-up of muscle tension.
In addition, zero emissions are produced when this breathable foam material is being made.
The Amerisleep mattress has a breathable Celliant® Textile Technology cover, which enhances your performance by helping to improve blood circulation and muscle recovery. This Celliant® Technology works to turn your body heat into infrared heat radiation, which has been clinically proven to aid in muscle recovery.
Despite the medium-firmness of the AS3 model, it is still responsive and will allow you to feel like you're sleeping on a cloud.
Those folks who switch into different sleep positions during the course of the night, i.e. combination sleepers, love this mattress as it is designed to feel comfortable for any sleeping position. Couples like the fact that movement doesn't transfer from one side of the mattress to the other.
Full, risk-free, 100 night Sleep Trials are offered with this mattress. So test it out to see for yourself if this mattress is as good as what other people say about it.
BONUS 3: The Zenhaven
The Zenhaven mattress by Saatva is amongst the most comfortable natural latex mattresses on the market. If you are someone that is looking for a mattress that doesn't sag and are also concerned about sleeping on a bed that is packed full of harmful chemicals, you won’t need to worry about that with this one.
Instead of synthetic latex like some mattress brands, the Zenhaven mattress is made in America with Talalay latex foam. It is topped with 100% organic New Zealand wool, which is all wrapped inside of a quilted organic cotton cover.
It is designed to have 5 ergonomic zones with different foam densities so as provide optimal lumbar support and relief from pressure points. Its base layers provide the foundational support and are made-up of strong latex foam support cores.
The latex, and all the support features work together very well to keep the mattress firm and sag free.
The GOTS certified organic wool, that is just under the outer cotton cover, is breathable and helps keep the body at a comfortable sleeping temperature. This New Zealand wool layer also functions as a chemical free and natural flame retardant.
Its quilted mattress cover is hypoallergenic and made from organic cotton. Treated with an exclusive anti-microbial solution, the cover prevents the growth of harmful bacteria or mold on it.
The mattress is flippable, so you can sleep on either side; one side offers a luxury plush level of support while the other is 18% firmer and provides pressure-free support. The luxury plush side (4-5 out of 10 on the firmness scale) offers great support to the curves of your body which makes it the preferred by side-sleepers and combination sleepers.
The Luxury firm side (7-8 out of 10 on the firmness scale) offers more uplifting support. This is what most average weight stomach sleepers and back sleepers need when sleeping.
Whichever side of firmness you choose, you will be free of any effects stemming from polyurethane foam or any pollutants.
Latex is the most durable material for mattresses and the Zenhaven twin and twin xl sizes can handle sleepers who are even 500 pounds in weight. The full, queen, king, California king and split king can have 500lbs people on either side of it at the same time.
However, being all-latex in its inner layers, its edge support is not great for larger people (250lbs plus). Saatva does offer in-home assembly, which is nice because this mattress is a bit heavier to carry or mover around than the majority of mattresses.
What to Consider Before Buying a Mattress That Doesn't Sag
A mattress might seem like a small purchase, but it can have a huge impact on your quality of sleep. If you're tired, grumpy, and lethargic during the day- there is a good chance that your mattress is to blame.
Here are 7 specifics to keep in mind when buying a mattress that won't sag over time or give out prematurely.
1. Coil type
The type of coil is significantly more important than the overall bed construction. The fewer coils in the mattress, the better- this means that there will be more space between springs across which you can sink.
This also means that each spring can exert less force on your body while you sleep so they won't be as likely to become compressed over time and allow sagging to occur. High-quality mattresses have either 18 or 19 coils per inch- anything less, don't waste your money.
Each coil should be labeled with things such as its "gauge" which means the thickness of each wire used in construction, measurements in inches or centimeters, and weight ratings. The heavier all of your combined components are, the longer they'll last you so look for coils that are slightly thicker with higher weight ratings.
2. Foam quality
Over 75% of the mattress will be foam so it's best to spend a little more money on this part. Cheap polyurethane foam that isn't dense enough will have poor durability and will probably show sagging much faster than you'd expect.
If you're interested in buying a memory foam and are wondering if memory foam mattresses sag, then look for at least two pounds per cubic foot in foam density. This means that it is a less clumpy, flimsy, and cheaper feeling than those memory foam mattresses that are denser, clumpier, and more expensive.
3. Mattress size and weight
The larger and heavier a mattress is, the longer it will last you. The more space there is between coils or foam, the less they can compact or sink- this means that your mattress should be expected to last much longer than cheaper ones that have tighter construction.
If you weigh over 200 pounds (90.7 kilos) look for thick layers of memory foam on top of an innerspring support system as well as coil counts over 350 per inch (10 cm). The thicker the better.
4. Material Quality
Measure how thick each layer of material is with a measuring tape and compare any differences across the surface area of the mattress.
If a mattress is cheap, it's likely because the manufacturer isn't confident in its durability. Find out how long the warranty is for and what type of conditions apply to it as durable mattresses usually tend to have longer warranties.
Those with a 10-year warranty may not be as good as ones that have a 15-year warranty- the longer the better, when it comes to shopping for a mattress that won't sag.
Look for those that have at least some space between coils or foam so that they can absorb your weight without becoming compressed too quickly.
6. Mattress type
If your mattress is too soft, you will sink in and feel the coils underneath. If it's too firm, you'll end up feeling like you're sleeping on the floor- try out a few different types of mattresses to figure out what works best for you. Generally though, the heavier you are, the more firmer and supportive mattress you will need.
If possible visit a showroom that allows you to test them out and then try comparing prices with online retailers such as Amazon or Walmart (or order directly from the manufacturers).
There are tricks and tips to make sure that any good online deal can be had without having to go through heavy sales tactics that can help you get the right mattress that won't sag without breaking the bank.
7. Box springs
This part is often forgotten or overlooked but it's important for your back and spine. Cheap box springs will sag faster than high-quality ones that aren't made out of cheap materials like particleboard.
Look online to see how much it costs to ship one and factor this into the total cost (or buy directly from a showroom if possible). You could also look into getting a platform bed frame that doesn't need them as these won't sag as quickly over time because they have no moving parts.
Not all mattresses that won't sag require box-spring bases. It is just that box-spring foundations increase the life-span of a mattress due to the extra support they provide. They are especially useful for innerspring and flippable mattresses.
A good mattress that won't sag shouldn't be too cheap, nor should it necessarily be outrageously expensive. If you're buying online look for retailers that have great reviews- especially when it comes to quality.
Higher price doesn't always mean better quality, but certain things are expected in high-end mattresses like tight coil counts, higher weight limits, and denser layers of memory foam.
Look out for sales throughout the year (especially around holiday periods) which will help you cut down on costs without sacrificing too much on durability or quality of the mattress materials used.
It's important to be an educated consumer when it comes to buying a mattress that doesn't sag. It doesn't have to be too complicated- just follow some of the steps above and you should be able to find something that keeps you happy while not breaking your bank.
- How do I make my mattress not sag?
For twin and full-size mattresses, flip the mattress every few months so both sides wear evenly. Replace any worn or damaged parts such as missing screws or springs (like box springs).
Add a piece of plywood between the mattress and box spring to make up for a sagging middle section of the box spring or add a board underneath each side of the bottom sheet near the foot of the bed to keep sheets from slipping off the corners.
Another way to solve this is to put an old blanket on top of the mattress before putting sheets on it so they don't slip off its surface. Weight can affect how fast a mattress might sag.
A longer term strategy, especially if you have the budget for it, is to use a mattress topper made from latex or high-density foams. Any low density foam topper will not resist sagging as soon as average weight user starts using it for several weeks so they should be avoided.
The mattress topper should be between 2 to 4 inches thick in order to provide the necessary levels of support to handle the mattress dipping. Toppers are more breathable than plywood and far more comfortable than blankets.
People who weigh more will exert more force on the bed, which could cause protrusions or dips even with newer beds that are designed to hold up well under significant pressure.
- Why does my bed have a dip in the middle?
A saggy middle section of a bed could be the result of many things, not all associated with wear or deterioration. A sagging middle may simply be caused by uneven weight distribution on the mattress.
If more people sleep on one side of the bed, the mattress will wear unevenly and cause a dip in the middle. If a large pet sleeps on one side of a mattress, it could cause temporary indentations that will go away if the pet moves to another spot or is no longer allowed on that part of the bed.
- How much sag is acceptable in a mattress?
If your mattress is no more than eight years old, one to two inches of sag in the middle section isn't cause for concern. A sagging bed may also not be a problem if you don't move much when sleeping or spend most of your time lying on it while awake.
Also, some mattresses are designed with weak spots that will develop a dip in areas where people typically sleep. These dips can usually be repaired by flipping the mattress over so the weak spot faces up again and then rotating it from head to foot every few months.
- Do mattress warranties cover sag?
Mattress warranties may offer coverage for sagging issues, but you'll need to read the fine print to know whether or not you're covered.
Depending on the warranty, it could be written in such a way that it will cover sagging only if it is less than 1 1/2" (3.8cm) deep and at least 2" (5cm) long and equally spaced apart across the middle part of your bed.
Other mattresses will also carefully define what they consider to be "sag." Therefore, we recommend reading your warranty before purchasing a new mattress to avoid any confusion later on.
- Is it normal for a new mattress to sag?
New mattresses can sag too, but it usually takes years for a mattress to reach this point. In most cases, the sagging is because of an old or damaged box spring that's no longer providing proper support.
A metal frame with squeaking springs could also be adding undue pressure to one side of the box spring, which can cause a dip in a new mattress. This is because the other side of the mattress has more support and so the poorly supported side fails to resist sagging.
If you notice sag, it may be time to get a new box spring or add another one underneath so both sides of the bed have equal support.
