By reading this article, you'll have an excellent grasp on what kinds of mattresses are on the market, so you can confidently purchase a mattress that will ensure comfortable sleep for years to come.

Here's where you can read all about 16-inch firm mattresses. Firm mattresses feature an indentation load deflection ranking of 34-36 pounds and are ideal for back sleepers. They encourage circulation and blood flow, so you can experience a deeper sleep. However, they may be uncomfortable if you're not accustomed to sleeping on firm surfaces, so it might take a few days to get used to them. Moreover, these mattresses can put painful tension on specific pressure points, including the hips and shoulders. They are built with a sturdy design, making them more durable and able to sustain more weight. Less likely to cave in, they will provide proper support, even after long-term use. However, 16-inch mattresses are higher off the ground, making them harder to get into and out of.
