What Is a King Mattress?
As previously stated, a king size mattress is indeed the largest standard measurement available in most companies’ sizing charts. These are perfect for couples that desire more personal space when sleeping, with a width of 76 inches and a length of 80 inches.
A king mattress (also known as an Eastern king) fits nicely on a king bed, which may be found in master bedrooms at least 12 by 12 feet in size.
They are best suited options for:
- Family with two children or owning a pet
- Sleepers who are tall
- Those who sleep in a combination of positions
These are large enough to accommodate two people plus a child or a pet. Because of this characteristic, the king mattress is a popular choice among parents who share a bed with their pets or children. The large sleeping area is also beneficial for active or combo sleepers.
Pros and Cons of a King Size Mattress
- It has enough room for a couple or a family with young children to sleep comfortably.
- It’s a fantastic choice for tall people or those who want to sleep sprawled out.
- It can help you sleep better by reducing tossing and turning.
- It might be a wise long-term investment in terms of pleasure and sleep quality.
- It may be too huge for certain people because of its bulkiness, making it challenging to roll around the bed.
- It can cost more than a queen or a full-size mattress.
- Finding covers and bedding that fit comfortably might be tricky.
Other Variants of King Size Bed
The king size bed is a popular and in-demand option worldwide. As a result, normal king mattresses come in various shapes and sizes to suit various needs.
The California king size mattress is one of the most popular variants. Though it has the same amount of space as a standard king-size bed, the California king is four inches wider and four inches thinner. Cal King mattresses are typically 72 inches broad by 84 inches long. These are great for extra-tall sleepers since they are extra long.
The split-king mattress is another king version. This is not a different size but instead is divided into two parts. A split-king mattress gives about the same amount of room as a traditional king mattress while also allowing each person to tailor their bedding (for example, mattress stiffness) to their preferences. Because each spouse may move their side independently and pick their resting position, this design works well with changeable beds.
To accommodate the specific needs of particular persons, several mattress manufacturers provide split California king-size and giant king mattresses.
What Is a Full Mattress?
Because a full size mattress would be neither too slim nor too wide, it falls somewhere in between of all bed sizes and dimensions. Full mattress is primarily designed for single sleepers in small spaces, measuring 54 by 75 inches.
A full mattress goes nicely with a full bed, which is also known as a double bed (even though it doesn’t have sufficient space to sleep two people).
Full mattress is best suited for:
- students in college
- adults who are single, and
- All who live in small areas, such as studio flats or hostels.
If you’re searching for a cost-effective and space-saving solution for smaller rooms (about 10 feet by 12 feet), a full size mattress can answer. Because they are wider than twins, you will be able to spread out or toss even while having enough room to walk about or add more furniture.
Pros and Cons of a Full-Size Mattress
- While sleeping, a full mattress provides plenty of areas to spread out and move about.
- Full mattress is less expensive than king-size mattresses, making them a more cost-effective alternative.
- It’s a fantastic option for couples that need more room than just a twin mattress but don’t want the extra length or width of a queen or king mattress.
- Full mattress is an excellent choice for growing children or teens who want extra space to stretch out.
- Full mattress occupies up lots of space in a bedroom, so you can have trouble fitting your furniture and other possessions around it.
- Moving a full-size mattress from place to place can be tricky, particularly if you have sharp corners or doors.
Other Variants of a Full-Size Mattress
Full-size mattresses, unlike king-size beds, do not have as many options. The complete XL mattress, which has the same breadth as a typical full-size mattress but is five inches longer, is the most noticeable.
Full XL Mattresses
Full XL mattresses have a 54-by-80-inch surface area, offering them a better alternative for taller persons who require extra legroom, so their feet don’t hang beyond the bed frame. However, because it is not one of the normal sizes and is not always readily accessible, you may have to acquire a custom-made full XL mattress.
Note: While the latter is not its variant, a full mattress is sometimes confused with a queen size mattress. This is because queen mattresses are just a half-foot wider than full beds, allowing them to accommodate two people and making them more ideal for couples.
Things to Consider While Buying a King or a Full Size Mattress
Not just the factors mentioned above but also various other factors are considered when choosing a mattress. A few of them are mentioned below-
The average room size needed for a standard king size bed is 12 feet by 12 feet. Whereas full size beds comparatively need a smaller room sized 10 feet by 12 feet.
