Pick the Right Mattress for You
Firm Mattresses

Interested in getting a firm mattress? A 15-inch mattress could be a good choice for you. Providing improved circulation, these mattresses promote deeper sleep. They are ideal for those who sleep on their back and have a 34-36 pound indentation load deflection ranking. They evenly distribute your weight, supporting your back as well as other vulnerable areas. However, they might be uncomfortable if you're not accustomed to sleeping on firm surfaces, so it'll take a few days to get used to them. In addition, they can put strain on specific pressure points, so if you want a mattress that relieves pain in pressure points, this is not the mattress for you.

Plush Mattresses

Experiencing joint problems? A 15-inch mattress could be helpful. Plush mattresses have a 19-21 pound indentation load deflection ranking and are ideal for individuals who usually sleep on their back, sides, or stomach. They have an additional support, which is great for those who have back problems or joint pain. These contouring support mattresses adjust to your body for superior comfort. However, they can become lumpy or sag with prolonged use, so your body won't be adequately supported when sleeping. In addition, they may be problematic if different sleepers will be using the bed, causing the surface to sag if there is a drastic difference in weight.

Soft Mattresses

If you're trying to find a soft mattress, Take a look at a 15-inch mattress. Soft mattresses feature a 19-21 pound indentation load deflection ranking and are perfect for those who sleep on their sides.

They fit well in studio apartments or other small living spaces and measure 54" X 75". However, they are short in length, so if you're 6'3" or taller, then you might want to consider a longer bed.
