The King Size Advantages
Nowadays, queen size beds are the most popular among all sizes. However, in the last time, a lot of couples wanting more space choose king size instead of the queen.
- A king size bed is more spacious and comfortable to toss and turn around. Its 76-inch width is much larger compared to the 60-inch width of a queen and the 72-inch of a California king.
- King size is a more luxurious choice. With its stylish look, you will feel like in a luxury hotel bed, especially if you get a model with a profile thicker than 10 inches.
- You have a great choice if buying a king size mattress. There are a lot of models of Twin XL, Twin, Full/Double, King, Queen, and California King, but anyway, if you need king size, you are always guaranteed to find any model available.
King Size vs California King and Twin Size Mattresses
- The dimensions of a king size mattress are 75 inches in width and 80 inches in length. It is ideal even for mothers and fathers who sleep with their baby in the middle
- California king mattress is only 72 inches wide and 84 inches long. It is great for tall people and those wanting to fill up more space in a bedroom.
- A standard twin size aka single mattress is 38 x 75 inches. In order to get the width of a king mattress, you will have to put 2 twin size mattresses together.

What is the Best King Size Mattress – Buyer’s Guide
To get what is the best king size mattress you can buy, take note of these points below:
- Comfort. There are many points creating the overall comfort – coolness, breathability, firmness level and so on. The sufficient airflow and cooling gel materials make a mattress remain cool regardless of the season.
- Firmness. Choose the firmness level according to your weight – the heavier a person – the firmer a mattress. Get plush, medium or firm mattress depending on your needs. There is no absolutely right formula, but back sleepers will feel better on medium-firm to medium mattresses, side sleepers gonna be satisfied with medium to plush firmness, and stomach sleepers – from medium-firm to firm. Anyway, descriptions of firmness are subjective – one person or one brand’s medium could be another’s soft or firm.
- Layers. Find out the layers of the mattress as well. As a rule, they are different types of foam and coils. Thicker mattresses, 12-inch for example, usually have more than two layers.
