Unlike the feather filled pillows, memory foam does not lose its shape over time. There will never be a need to “fluff” this type because it is designed to, as stated before, resist motion transfer. They are made primarily from polyurethane, and material specially manufactured to keep its form for years to come, which also lends to the products longevity versus traditional ones that should be replaced roughly every 1 to 3 years.
The most highly recognized benefit of owning a memory foam pillow is its ease of motion transfer resistance. While first receiving recognition using its counterpart, the memory foam mattress, this technology enables the cushion to essentially build a mold around your head for optimal head and neck support. This benefit is also known to lead to a reduction in snoring thanks to foam keeping the neck aligned and air passages open.
