    What is a King Mattress?

    King-size mattresses come in different sizes, the most popular being a king. King size provides more sleeping space than two twin size beds combined and offers almost 7 feet of width! This makes it perfect for couples who want their private spot without geographically separating themselves from one another while also accommodating pets who enjoy cuddling up next to you during sleep time.

    Pros 

    • Spacious for couples
    • Couples can sleep with their children and pets comfortably
    • Easily available since it is a popular option 

    Cons 

    • Can be expensive when compared to a full 
    • Can be harder to fit into a smaller room

    What is a Full-Size Mattress?

    If you are looking for the perfect spot to curl up and read, then an extra-large mattress is what’s needed. These beds make great guest rooms as they offer plenty of space where two adults can sleep comfortably without feeling cramped together like sardines in a tin!

    Pros 

    • Less expensive 
    • Spacious for single adults 
    • It can be easily moved 
    • Can fit into smaller rooms

    Cons 

    • Is not suitable for tall people 
    • Can be slightly congested for heavier couples

    Variations in King Size Mattress

    Since the traditional king-size bed is one of the most popular choices today, there are variations of the same in different dimensions. 

    California King 

    The California king-size mattress is a sought-after variant of a king amongst tall people because of its length. It is four inches longer and four inches narrower than a traditional king bed. In fact, a Cal king is known as a Western king, while a standard one is known as an Eastern King mattress.

    Split King 

    A split king is another variant of a standard king. While it sports the same dimensions as a king, it is split in the middle, where each side is the size of a twin XL mattress. Due to this split, each side can be used independently. Today, you will also come across adjustable bed bases that will allow you to maneuver your side as per your preference. 

    You will also be allowed to choose different firmness levels on each side according to your sleep requirements. You can also find a split California king, but they are not easily available compared to a regular king. Finally, there are oversized king mattresses too, but they are a very rare find, and not all brands carry the same. You may have to custom order it if you are looking for one.

    Variations in Full-Size Mattress

    Unlike a king, a full-size mattress doesn’t offer plenty of variations. However, a full XL is almost 5 in longer than a traditional full bed size. A full XL is excellent for tall sleepers over 6 feet 2 inches. However, a full XL might not always be readily available, and you might have to custom order the same. 

    Often, a full bed is compared to a queen because the sizes are pretty close. Even the bed sheets and comforters are usually sold with a queen/full label because they are suitable for both options. 

    How to Choose between King vs Full 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-

    Room Size

    The minimum room size requirement for a king size is 12 feet by 12 feet. Full size beds require a room size of 10 feet by 12 feet. Having considered the room space, make a wise choice as in the end the room shouldn’t be a dungeon for you to live in. It needs to have other furniture, enough walking space after the placement of the bed.

    Price

    The price range for both these mattresses is influenced by their size, accessories, materials used, and brand. Compared to the full size mattresses, king size mattresses are pretty expensive because of their size, brand, materials used. So, if you are facing a crunch and an individual then opt for a full size mattress. 

    Height

    The height of the occupants is a major determinant in this king vs full debate. With 80 inches in length, a king-size mattress can accommodate taller people. Whereas with the length of 75 inches a full size mattress can accommodate people who are shorter than 6 feet.

    Which mattress is best for you?

    After considering all the factors, you definitely know what suits your needs the best. Hence, choose wisely and have a healthy and happy sleep!
