Are you buying a new extra firm thick mattress? Here are some things you should know. These mattresses are built with an indentation load deflection ranking of 39-42 pounds and are perfect for people who sleep on their back. They encourage circulation and blood flow, allowing you to enjoy deeper sleep. However, they can put painful tension on specific pressure points, including the hips and shoulders. Additionally, they can be uncomfortable if you're not used to sleeping on firm surfaces, so it can take a few days to get used to them.

Thick mattresses are suitable to use with standard-size sheets, so you can find linens and other bed accessories that fit. Less likely to cave in, they will provide substantial support, even after long-term use. These thick mattresses will revamp any room. They have a strong build, making them more durable and able to sustain more weight. However, these thick mattresses are more difficult to get out of and into. They provide poor temperature control, trapping heat and air inside of them. In addition, they can be pretty heavy, making them hard to move and flip.

The Ins and Outs of Extra Firm Thick Mattress Sizes
King-Size Mattresses

Trying to figure out whether you need a king-size mattress? Read on to learn about some of the facts. These mattresses are ideal for couples, providing extra space for you to spread out. They are perfect for master bedrooms and measure 76" X 80". One downside is that they are not great for small areas, since they can make the room look somewhat cluttered.

Now that you know some reasons to get a king-size mattress, if you think they're a good choice for you, take a look at this one.

Full-Size Mattresses

Looking for a good full-size mattress? The super comfortable extra firm thick mattress might be right for you. Full-size mattresses are suitable for studio apartments or other small living spaces and measure 54" X 75". They are ideal for couples, offering a tight fit between the two sleepers. However, full-size mattresses are short in length, so if you're 6'3" or taller, you might want to look for a longer bed. Additionally, they have a narrower sleeping space, so you will have limited space to move when sharing your bed with someone else.

Queen-Size Mattresses

Still deciding what size extra firm thick mattress to get? These mattresses measure 60" X 80" and are perfect for master bedrooms. They are designed to adequately accommodate couples, providing enough space for two people. Something to consider is that they are not ideal for small areas, since they can make the area look somewhat cluttered. In addition, they are smaller than king-size mattresses, so if you like having a wider sleeping area, you should think about getting a larger mattress.
