This reduces localized pressure on areas such as the hips, shoulders, and spine. For instance, individuals experiencing arthritis or fibromyalgia may find significant relief due to the minimized pressure on sensitive joints.

• Density and Compression Modulus

  The density of the memory foam affects its ability to provide sustained pressure relief. Higher density foams generally offer greater support and resistance to compression, preventing the body from sinking too deeply into the topper. The compression modulus, a measure of stiffness, determines how the foam responds to applied pressure. An appropriate balance between density and compression modulus is necessary to achieve optimal pressure relief without compromising support.

• Influence on Spinal Alignment

  Proper pressure relief contributes to improved spinal alignment during sleep. By minimizing pressure points, the 6-inch memory foam layer allows the spine to maintain its natural curvature, reducing strain on back muscles and ligaments. This is particularly beneficial for individuals with pre-existing back conditions, as it can alleviate pain and promote a more restorative sleep posture.

• Impact on Circulation

  Excessive pressure on certain areas of the body can impede blood flow, leading to discomfort and restlessness. The pressure-relieving properties of a memory foam topper promote better circulation by reducing compression on blood vessels.
