Best 15-Inch Full-Size Mattresses


Our review process

No more trying to get through confusing articles and infographics to try to figure out which 15-inch full-size mattress you need! By reading this guide, you'll have an excellent grasp on 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.

Before deciding on your new 15-inch full-size mattress, there's some stuff you'll want to know. These mattresses measure 54" X 75" and are suitable for studio apartments or other small living spaces. They are roomy enough for an individual without taking up as much space as a queen-size mattress. However, they have a narrower sleeping space, so you will have limited space to move when sharing your bed with someone else. Also, they are short in length, so they might not be a convenient option if you're taller than 6'3". Less likely to cave in, 15-inch mattresses will provide substantial support, even after extended use. They are built with a strong design, making them more durable and able to sustain more weight. However, they are thicker than most mattresses, so finding bedding that will cover the top and sides is much harder.

Deciding Which Comfort Level Is Best for You
Firm Mattresses

They are ideal for back sleepers and are built with an indentation load deflection ranking of 34-36 pounds. These improved circulation mattresses promote deeper sleep. Something to keep in mind is that they can put painful tension on specific pressure points, so if you want a mattress that alleviates pain in pressure points, this is not the mattress for you. Also, these mattresses may be uncomfortable if you're not accustomed to sleeping on firm surfaces, so it'll take a few days to get used to them.

Soft Mattresses

Are you searching for a soft mattress? A 15-inch full-size mattress could be a good choice for you. These mattresses are built with a 19-21 pound indentation load deflection rating and are suitable for individuals who tend to sleep on their sides.

These back problems and/or joint pain mattresses help to relieve you of any back problems or joint pain that you're experiencing. However, they may be problematic if various people will be sleeping in the bed, causing the surface to sink if there is a significant difference in weight. In addition, they are more likely to cave in over time, so it's possible that they'll be less comfortable and supportive since your body won't be aligned properly.
