What is a Knee Pillow?

A knee pillow is the type of pillow which is placed underneath or in between the knees while sleeping for adequate comfort and perfect body alignment while sleeping. This pillow stops the knee from rubbing on each other.

Generally, sleeping on the stomach is not quite encouraged, and therefore in a bid to help the spine, it is better to sleep while lying on the back.

  • Hourglass design

This design seems to be the most common design for knee pillows and most cases the cheapest option too.

The hourglass contouring matches with the knee’s natural curvature for more comfort, which keeps the two legs’ in place all through the night.

  • Wedge design

Wedge designs have a half-moon or triangular shape, and they are more appropriate for the back sleepers’ when stocked under the knees.

  • Body design

The body designs are exclusively wide and are built to match an adult’s length.

Many people use this pillow in between their legs’ to reduce friction between the legs’ and knees and back pressure.
