Choosing the right mattress firmness is crucial for ensuring proper support, comfort, and spinal alignment. The firmness level affects how well your mattress conforms to your body, relieves pressure points, and supports your preferred sleeping position. Soft: Highly plush and contouring, best for side sleepers and those who prefer a sinking-in sensation. Medium-Soft: Still contouring but with slightly more support, suitable for side sleepers who like a balance between softness and support. Medium-Firm: The most popular choice, offering a mix of support and comfort, ideal for back sleepers and combination sleepers. Firm: Provides the most support with minimal sinkage, best for stomach sleepers and heavier individuals who need extra support. Choosing the right mattress firmness is essential for a good night’s sleep and overall health. If unsure, a medium-firm mattress is a safe choice, as it suits most people.
