Do memory foam pillows really help with sleep comfort?
Memory foam can improve sleep comfort by contouring to the body’s unique shape and distributing weight evenly. This reduces high-pressure areas that lead to tossing and turning. Its effectiveness is highest for those who prefer a “sinking” feel rather than a bouncy or firm surface.
How long does it take to adjust to a new pillow?
Most people require between 5 and 10 nights to fully adjust to a new ergonomic pillow. During this time, the body’s muscles are adapting to a new alignment, which may cause minor, temporary discomfort before the benefits become apparent.
