How Medium-Firm Mattresses Support Your Back
If you have back pain, the chances are that your spine is out of alignment somehow. A mattress that is too soft or too firm can make this worse. If your mattress is too hard, it can shift your posture out of alignment, particularly if you sleep on your side or stomach. Medium-firm mattresses are a common middle ground, and studies of different mattress designs point the same way.[2] If you have back pain that doesn’t go away, see a doctor.[3] A medium-firm mattress is likely to accommodate both of you between a married couple who each sleep in different sleeping positions. A mattress with more than one layer of varying densities often provides better pressure point alleviation than an entirely firm mattress. A very soft mattress can let your hips sink too far.Different Types of Medium Firm Mattresses
Here is a discussion of the different types of medium-firm mattresses available so you can decide on the type to suit your needs.- Air Mattresses – good air mattresses have inbuilt pumps to inflate themselves and are sealed double-tight. Many people feel that inflatable mattresses do not keep their inflated state over time, becoming softer with age. The main advantage of inflatable mattresses tends to be that you can fill them to match the exact medium-firm you are looking for.
- Water Mattresses – water mattresses are very similar to air mattresses, allowing you to feel weightless. Water mattresses are softer than air mattresses and are not usually the best choice for medium-firm mattresses.
- Foam Mattresses – foam tends to have the best results for medium-firm back support. In particular, memory foam will conform to the exact shape of your form as you sleep, allowing you to change positions while still holding a good posture for your spine comfortably.
- Spring Coil Mattresses – these mattresses make good contenders to foam mattresses if the springs are individually wrapped, silent, and usually covered in a layer of foam regardless. Cheaper open coils can sag over time.
