Types

Foam pillows are made from either "memory foam" or a latex-based foam. The effect is essentially the same: a pillow that forms to the shape of the head and returns to its original shape after pressure is removed. Foam pillows can be found in standard sleeping sizes and in decorative shapes.

Health Benefits

Foam pillows cradle the head with support instead of sinking into a shapeless lump like traditional feather pillows. This proper support can help reduce snoring, improve back and neck alignment and create a more restful and prolonged period of sleep.

Considerations

Foam pillows can cost significantly less than traditional feather pillows. Down pillows can run as high as eighty dollars for a high-quality, hypoallergenic model. Foam pillows can be purchased for as little as twenty dollars, and last much longer, as they resist the bunching and lumping effects of regular pillows.

Asthetic Benefits

Traditional down pillows grow lumpy and misshapen over time. Not only is this bad for comfort, it's also unsightly. Foam pillows hold their original shape, so the appearance of a foam pillow will be more attractive over time than that of a feather model.

Recommended

Some foam pillows are created by doctors specifically to increase the health benefits found in proper sleeping. For example, the "Snore No More Pillow" by Polar Foam offers great support and angling to decrease the tendency to snore.
