Top 16-Inch King-Size Mattresses


Our review process

We've done all the heavy lifting researching 16-inch king-size mattresses. That way, you don't have to pour over confusing articles about choosing the right one for you. By reading this article, you'll have an excellent understanding of what types of mattresses are available on the market, so you can confidently purchase a mattress that will ensure comfortable sleep for years to come.

Here's what we think you'll want to know before buying a 16-inch king-size mattress. These king-size mattresses measure 76" X 80" and are perfect for master bedrooms. They are suitable for couples, offering extra space for you to move around. However, they are large and heavy, making them hard to transport and flip. Moreover, they are not ideal for small spaces, since they can make the room look somewhat cluttered. Less likely to cave in, 16-inch mattresses will provide adequate support, even after extended use. They are built with a solid build, making them more durable and able to sustain more weight. However, they are thicker than most mattresses, so finding linens that will cover the sides and top is much harder.

Firm mattresses allow for even weight distribution to support your joints and other vulnerable areas. They are built with an indentation load deflection rating of 34-36 pounds and are perfect for those who tend to sleep on their back. However, they can put strain on specific pressure points, including the shoulders and hips. Also, they can be uncomfortable if you're not accustomed to sleeping on hard surfaces, so it can take a couple of days to get used to them. If you think a firm comfort mattress is a good choice, check out this one.

Plush mattresses feature a 19-21 pound indentation load deflection rating and are suitable for those who tend to sleep on their back, sides, or stomach. These back problems and/or joint pain mattresses help ensure that any discomfort that you're experiencing doesn't get worse. They feature contouring support, which adjusts to the natural curves of your body for optimal comfort.
