Need sleep? The search for the best king size mattress, can be a long and arduous one, with lots of confusion and fatigue from the endless choices and features. The objective of this review, is to inform you on how to make the best choice, and offer an unsolicited recommendation. When looking at mattresses, you will be looking at the actual structures, especially if you’re doing this completely online, which many people are doing nowadays. The best king size mattress, according to this humble reviewer, is the one that offers both high-density foam and coils. A lot of reviews will rank foam mattresses as one of the worst, and admittedly, they are an underdog, but, they’re extremely affordable. Now that you know this, you’ll want to get the biggest bang for your buck, right? Right.

Introduction

What is the Cost of A Comfortable Mattress and How Durable They are?

The best king size mattress, within the price range of $300 to $700, will offer you comfort, and support although keep in mind, that the durability is a weaker point here. The products you’ll find in this review, include Gel Foam Mattresses, High-Density Foam Mattresses with Fiber material and Foam Mattresses with varying coil count and distribution. The choice you’ll make, will depend on how you qualify good sleep. If you’re a couple, you’ll want something that avoids feeling the movement of the other. If you’re a couple with back and neck-pains, you’ll want something with better lumbar support. Sweat, ventilation, temperature can make a big difference in the quality of sleep as well, which is something you won’t even be able to see or feel if you’re shopping at a store.

So, this information is pretty powerful stuff. Sweating is a natural occurrence, while sleeping, and foam mattresses can handle the sweat for a bit, but there might be some washing and drying involved, which isn’t the case with latex and other types of mattresses. The coolness of a the very best king size mattress is also very important, as it can really be the difference between a sense of breathability or being sunk into a hot pool of wet cotton or wool, and you probably don’t want that.  Gel foam mattresses advertise themselves in keeping a cool atmosphere for a refreshingly cool, and somewhat sturdier quality of sleep.

What Type of Mattress is the Best for Lower and Upper Back Pain?

Depending on the type of researcher you are, you might’ve heard about coil counts and/or spring beds. Coil count, and all the different spring structures offer the lumbar support you might need for lower or upper back pain. The best king size mattress will offer coil count, and spring beds to help with the quality of your sleep

Keep in mind though, if you are experiencing severe lower and upper back pain, the longer-term orthopedic effect will outweigh the difference in cost. I think this best mattress for bad back  guide is going to help you more.

Why Coil Number is Important for Choosing the Right Mattress?

If you haven’t opened a new tab by now, let me explain that coil numbers, while important, aren’t as important as the design of their structure. Springs or coils come in different heights, which account for the cost difference because the longer they are, the more flexible they are to your body’s positioning. So, take a look at the coil count but keep in mind Inches and material. With coil material, just stick to metallic ones – you’ll see in this review, they agree with me, so take my word for it.

What is Foam Density?

King-sized Foam mattresses that feature high-density foam, and fiber material use Zone-systems to offer the lumbar support coils promise. It’s what makes them affordable, because the Zone-systems are reliable except the durability is a weaker point. Lucky for you, some of these products have friendly warranties, so look out for that because it’s also not too common for mattresses in this price-range.

Foam mattresses remain firm, for a bit, but you’ll find they are also very soft. Some mattresses include a pillow-touch or quilt, which ups the overall quality of the mattress. That’s the thing with foam mattresses, every added feature seeks to improve the support for a luxurious experience. In the world of only-foam mattresses, it’s a game of mixing and matching features to deliver a somewhat targeted need. Think of it as a one-trick pony, that really likes to please you, but unfortunately only knows that one trick. But again, don’t just take my word for it restless sleeper, and read about it some more here . If you are a Stomach sleeper , you should this guide for stomach sleeper’s mattress.

What Do You Need to Figure Out to Make the Best Decision?

Who are you?Not in a philosophical sense, but what do you need out of this mattress the most, is what you need to figure out to make the best decision. Are you afraid of dust-mites? (I am by the way). Do you prioritize motion sensitivity over coolness? Is allergy-resistance a factor for you?When you’re sleeping, do you sleep better knowing that the king-sized mattress is manufactured with low VOC levels i.e. car-gas emissions and so forth? Ask yourself, when you’re looking at the features, whether this is the feature that truly matches what you need. In fact, write a list of all the products you find, and rank the features.

Pros

  • It’s really comfortable, because it is extremely breathable. The quality of the material of the mattress, is what keeps the temperature cooled down, and it adapts to weather changes.

Cons

  • It does give great support but durability might be an issue for this mattress. The firmness could also be an issue over time, and sweat may collect as the material is a bit different so washing/drying will probably be routinized for youOne of the great things about this mattress is that it is very useful for overweight people. In addition to that, it really helps with weather changes. Unfortunately, the material of this mattress makes it a weaker option, which is why it is ranked so much lower.

Here is hot mattress solutions.

Dreamfoam Crazy Quilt Pillow Top Mattress

Dreamfoam Crazy Quilt Pillow Top Mattress

This mattress offers the 3-Zone support system, which is really the reason why Foam Mattresses can offer a very solid lumbar support for your back and neck pain. This mattress, will make you very comfortable at a very reasonable price. The DreamFoam mattress also offers an additional feature, called the Quilt Pillow, which provides an extra softness to your sleep.

Pros

  • The 3-Zone Support System will truly offer the necessary support that you will want when sleeping. It doesn’t have the lumbar support that you may seek in a springboard-based mattress, but the 3-Zone Support does distribute the weight across the mattress for one’s body.

Cons

  • The mattress is an affordable mattress, for both couples and single people. It is a great option, for those who don’t’ want to spend too much money, and aren’t interested in condition-specific features such as allergy resistance.

Features

  • People who prefer softer mattresses – Quilt Pillow
  • Customers who also want something cheaper
  • Overweight people – as it offers lumbar support & distributed pressure

Dynasty 12-Inch Gel Memory Foam Mattress

gel foam mattress reviews

This mattress will keep things very nice and cooled down. So if you want something that is both thicker and has the Gel-Foam, this is a really great option because it really does make sure that you’re sleeping in a comfortable and breathable environment.

Pros

  • It’s very breathable, gives space and cools people down while sleeping. Expect the Oven Effect to only be an issue, for when you’re turning on the oven i.e. it’s not an issue anymore.

Cons

  • The price is higher than most of the products on this list, but will do the trick if how breathable a mattress is and temperature are very important to you. Which, many people say it is.
  • This mattress is the mattress to choose because it tackles, in my humble opinion, the biggest issues with foam mattresses. Gel Foam Mattresses offer the Cool breeze sensation, which keeps it very cool and keeps it very comfortable without the Oven effect that you’ll find with many of these products. The price range is high, which makes it one of the more expensive ones in the list.

Features

  • It’s a great price for those who are looking for something of better quality without too high of an expense.
  • Gel-Foam makes this perfect for people who need breathable features
  • Overweight people – as it offers lumbar support & distributed pressure

LUCID 8 Inch Memory Foam Mattress

It’s an absolute front-runner in this list and ranks higher because of the quality of the mattress, due to the material and the Dual-layered factor.
Pros

  • The foam mattress is thicker than the rest, which means that the typical problem of going soft Is less of an issue than it is with thinner mattresses.

Cons

  • The only issue with this mattress, is that it isn’t one of the mattresses with a Zone-System, so it’s not meant to help with lower back and upper back pains. So if you do have orthopedic issues, this one isn’t the one to go with.

Features

  • Thinner Foam-Density allowing less movement between people
  • Customers who also want something cheaper
  • Overweight people – as it offers lumbar support & distributed pressure
  • Someone looking for an extended warranty – it has a 25-year warranty

Brentwood Home Bamboo Gel 13 Memory Foam Mattress

Bamboo is an up and coming type of material, that allows companies to manufacture in more environmentally friendly ways, and with better quality material. This one is suitable for young couples, college students and people who are experiencing lower back and upper back pains. The comfort level of this mattress is one of the major reasons why it is so well-received by people.

The mattress is definitely something that has been well-received by people, and considered to be very comfortable. It is highly recommended as material, that allows people to sleep with the assurance that they haven’t paid an exorbitant price, but still bought a reliable product.

Cons

  • As with many of these mattresses, despite the material, the durability and longevity remains an issue. The longevity and durability will decline over time, so you’ll find that you may sink into it as well after 6 years, but that’s the norm with many of these mattresses.

Signature Sleep Contour 8-Inch Independently Encased Coil Mattress

Front of Signature Sleep Contour 8-Inch Independently Encased Coil Mattress

This mattress, like the one after it, has coils and foam. Definitely, a product that can be considered a steal. It offers couples, a great sense of comfort as well as sturdiness. It does have a boxspring, so this can offer some lumbar support.

Pros

  • This mattress, does have the coil count that one might expect, and can give the support that you need and desire. The affordability of this mattress, makes it an absolutely solid choice if you’re looking for something that won’t break, or sink you into a very hot pool of sweat.

Cons

  • The Foam material, in this case is of lesser quality than other mattresses because it is constructed differently. It doesn’t offer the 3-Zone Comfort, which can offer the distributed softness-firmness effect that offers customers a completely relaxed experience.

Features

  • Thinner Foam-Density allowing less movement between people
  • Customers who also want something cheaper
  • Overweight people – as it offers lumbar support & distributed pressure

Home Life Comfort Sleep 6-Inch Mattres

Corner Home Life Comfort Sleep 6-Inch Mattres

When looking for something simple and very affordable, and perhaps the most temporary, this is absolutely the mattress for you. It is suitable for couples, but provides the best comfort for a single person. This is absolutely a find for budget-hunters.

Pros

  • The foam density, at 6-Inches, is really no-frills structure. It’ll keep things sturdy for a temporary amount of time, and provide some softness so comfort won’t be an issue for at least some time. But keep in mind, that this is something that is temporary. The affordability of this product is perhaps the strongest point here. So, you should definitely consider this if you’d like to buy something that is both cheap, and somewhat reliable. Also, keep in mind that, because the foam density is in fact shorter, the firmness of this mattress is more likely to remain.

Cons

  • The foam-density may cause it to be somewhat too firm for some, but, as mentioned earlier, since it is made of foam, the softness will remain. Unfortunately, the sweat will be absorbed and washing and drying will be necessary on a regular basis.

Features

  • Thinner Foam-Density allowing less movement between people
  • Customers who also want something cheaper
  • Overweight people – as it offers lumbar support & distributed pressure

Signature Sleep Memoir 12-Inch Memory Foam Mattress

king size memory foam mattress

With the spring structure, the foam mattress uses the 12-Inch to remain comfortable and soft for people. It’s really the best for couples. It’s another option that doesn’t offer too many frills, but can definitely offer good support.

Pros

  • If you don’t have back and neck pains, this is as good an option as any. And in terms of durability and longevity, this one does last and it has a very good warranty.

Cons

  • When comparing the mattress to other foam-coil mattresses, perhaps the durability is lacking but the affordability definitely makes it a very good find.

Features

  • Thicker Foam-Density for Ultimate softness
  • Customers who are looking for a mid-range price for some durability and reliability
  • Overweight people – as it offers lumbar support & distributed pressure

Englander Finale 10-Inch Innerspring Mattress

full view Englander Finale 10-Inch Innerspring Mattress

As mentioned earlier, coils and spring layers will create a more organically shifting lower layer that bends and twists according to your positioning and shifts. This creates pressure points on your body, that can help improve your overall health in terms of back and neck pains. Foam mattresses, like this one try to compensate for not having the coils that can do this with the 3-Zone Support System.

Pros

  • It’s very affordable, and it still offers the 3-Zone Support System, as well as the Plush top layer. This makes the mattress something very suitable for someone who wants the soft material, comfort and support system.

Cons

  • Of course this mattress doesn’t have the lumbar support ideally found in Coil-Foam mattresses. Also, it’s a little more expensive than some of the other Foam Mattresses, however the additional features, can make this an appealing option.

Sleep Master iCoil 13 Inch Euro Top Spring Mattress

corner view Sleep Master iCoil 13 Inch Euro Top Spring Mattress
This mattress will offer the lumbar support, that can really offer both a soft experience with a strong coil structure underneath. As explained, with coil length there is better flexibility for body shifting and positioning while sleeping. The lumbar support you may be seeking, with an additional higher foam density can be found in this mattress.This is considered to be one of the best mattress for heavy people.

Pros

  • This mattress will offer the strong support that you require from a mattress. And it is absolute as solid choce, if you want something in a lower price range.

Cons

  • A lot of the mattresses in this list, can be a littl emore expensive, or a little cheaper, but they have certain features that will compensate for eithe lacking lumbar support, or lower Foam Quality. This one is a solid option but it won’t be extra soft or extra supportive.

Features

  • People looking for a Coil-Foam Combination
  • Customers who also want something cheaper
  • Overweight people – as it offers lumbar support & distributed pressure

Final Verdict

Personally, I feel the best king size mattress is the Breezy, Cool and Ultimate Comfort for Over 500 Dynasty Mattress Cool Breeze 12-Inch Gel Memory Foam Mattress, King Size. The reasons being that, I’m someone who doesn’t suffer from back or neck-pains, so orthopedic benefits are not so important for me. The most important feature for me is the comfort and price-range, which makes it a good choice for me. The price of less than 500 is quite attractive, compared to the much higher prices that one may find online or in a store. Still, you may find better-suited mattresses depending on your needs. Do you need a mattress which is best for heavy people? Here is the guide for you Best Mattress for Heavy People.
