It is only natural if you want to have the best King Size mattress there is. But know this, a lot of mattresses are actually King Size. You would be hard pressed to find ones that are not. Although there indeed are such mattresses in the top lists I’ve made, and quite a number of them at that. Those usually come in one or two sizes, but even when they don’t necessarily have a King Size.
But I did include several such mattresses in the top lists so far, and that’s why we need to make a review specifically for king size
What’s so special about the King Size?
Other than the size itself? Nothing really. But, unlike how often people now keep saying these days, sometimes size does matter. It is one of those special circumstances. The thing is, first of all, who is going to sleep on it. You can give such a bed to a kid, of course, but that usually would be too extravagant. Kids don’t need beds that large. On the other hand, if you don’t sleep on the bed alone, king size might be what you want… as long as you can fit the bed into your bedroom
Bed frame
But, first of all, before you acquire a mattress, you should already have a bed. A king size bed in our case. Usually, anyway,
People usually buy mattresses to put them on top their existing bed frames. That’s why it is not an issue to decide what size a mattress you need. But! There is always a “but”.
But there are some special circumstances.
An air mattress, for instance, unlike many other types of mattresses, they are meant to be used standalone. And when I say standalone, I mean without a bed frame. It can be either a guest bed or a camping mattress… but in either case, you don’t have a bed frame to evaluate if you need it.
Size match
It is important to know what size you have specifically and what size you need. Scratch the standard sizes, it’s always better to know dimensions precisely. It matters little when we’re talking air mattresses, ironically, but it is a big deal with any other type of mattress, which means, with any mattress to put on top of a bed frame.
The top five will not have any new mattress. Every mattress has been reviewed already, but today we’re picking them because of their size.
Top 5 of Best King Size Mattress
5. Signature Sleep 12-Inch Memory Foam Mattress
The mattress, as any other in this top list, is available in King Size. It has a slight odor, but the scent fades away completely very fast, even though the mattress is infused with chemical flame retardants and meets federal flammability standard 16 CFR 1633.
It is a high-density mattress, so it quite firm, but only as long as there is no heat to warm it up and no pressure to give in under. The mattress is very good for people with any kind of back problems. It also works perfectly to relieve pressure points. Thanks to that, whatever muscle tension you might have, would be completely annihilated.
The mattress is rather unwieldy when unpacked. Since it’s also heavy, I recommend unpacking it before using. It is very hard to handle without help. Still, it is a very good mattress. Check out 3,500+ customers reviews on Amazon.com!
- Low price
- Meets fire standard 16 CFR 1633
- Comfortable high-density foam
- Comes in a bag easy to handle
- Inflates relatively fast
Cons:
- Hard to move around after inflation
- Foam becomes softer in high humidity environments
4. Sleep Innovations Shiloh 12-inch Memory Foam Mattress
A medium firmness mattress. It is not the best mattress for kids or lightweight people, but it works very well for those of us who happen to be average or heavy. They would find it softer.
Of course, if you’re lightweight and prefer firm sleeping surface, the mattress would work for you as well. It all depends on your preferences.
The mattress has a 9.5-inch thick support foam layer and a 2.5-inch thick top layer made of memory foam. The core layer provides support, whereas the top layer is used to reduce pressure points. The mattress is firm, just like many others of the best memory foam mattresses, but the memory foam layer might grow softer eventually. Whether it is a boon or a drawback is up to you. Either way, you can order the mattress on Amazon.com right now. Besides, the mattress comes with a warranty, so if you’re not happy with your mattress grown softer, do not forget that is a breach of warranty.
While the mattress has the same odor issue any other memory foam mattress has, the scent is bearable enough and easy get rid of it. The real issue would be heat traps, also specific to memory foam, but this problem is not any bigger than with any other memory foam mattress.
- Thick memory foam layer
- Comfortable on any surface
- Made in the U.S.A.
Cons:
- Can be too firm
- Can grow soft after some time
- Unclear whether meets fire standards
3. Tuft & Needle Mattress
A perfect average mattress firmness-wise. If you are not aware of what mattress would work best for you, the average is something to start from.
This is a mattress very suitable for sex, not just sleeping. It combines two usually incompatible features: it’s bouncy and eliminates motion transfer. The sides are a little bit sloped. They facilitate getting out of the bed without disturbing the partner, but also make it a little bit too easy to slide out of the bed if you prefer sleeping close to the edges.
This is not a memory foam mattress. That means it does not retain heat as much as memory foam and at the same inflates really fast. When you buy it on Amazon.com, make sure to take that into account.
- Relieves pressure
- Cool sleeping
- Good for sex
- Near odorless
- Inflates super-fast
- Made in the U.S.A.
Cons:
- Unclear whether meets fire standards
- Sloped sides
- Does not conforms to the body perfectly
2. Sleep Master Memory Foam Mattress
А good memory foam mattress. It is double-layered. Maybe not the cheapest purchase, but worth its price. The foam has high density. It is also CertiPUR-US certified.
The mattress does not have a strong odor. It takes it two days to inflate at most, however, make sure the mattress does not stay packed for more than 72 hours.
You might find the mattress a bit firm, but don’t forget that it is a memory foam mattress, so let it take some time before it warms up. The core foam layer makes it possible to put the mattress on the floor. It doesn’t matter whether you put it on top of a bed frame or the floor because of that.
If you are not convinced yet, make sure to read the reviews on Amazon.com.
- Low price
- Easy to set up
- Inflates relatively fast
- Comfortable on any surface
- CertiPUR-US certified
Cons:
- Possibility of hot sleeping
- Thin memory foam layer
1. Perfect Cloud Supreme 8 Inch Memory Foam Mattress
It is an expensive mattress. The support layer is made of unique core foam. Heavy due to the high density, this mattress is nevertheless very comfortable. Unless you were planning on moving it around, this won’t be too big a problem.
Besides, this mattress is deformation-proof. Kind of. What I mean it would not suffer any deformations as long as it remains sealed air-tight. You can order it on Amazon.com right now, and then wait for a couple of months before you move into your new house, only then unpacking the mattress – and it would be perfectly fine. Besides, the mattress comes with a removable cover.
- Highly comfortable
- Easily removable cover
- CertiPUR-US certified
- Made in the U.S.A.
Cons:
- High price
- Hard to move around
Bottom line
King Size mattresses are not limited to one or two types, but some it just so happens that the most popular King Size mattresses are made of foam. It makes sense since it’s really easy to produce mattresses of whatever size, as long as we’re using foam to make them.
