Best Knee Pillows Buyer's Guide
Many people find that sleeping with a pillow between their knees helps reduce pain and pressure, as well as improve circulation in both legs. Knee pillows are most popular with side sleepers, although back sleepers may place them beneath both knees for better support and comfort. Pregnant women and people with back or knee pain may also benefit from using them. Knee pillows come in a wide range of shapes and designs to accommodate sleepers with different preferences, and some models come with knee straps that help keep the legs in place. Most knee pillows are available for $30 or less.
This guide will look at some of the most common designs for knee pillows, as well as people who benefit from using them, tips for first-time buyers, and our picks for the best knee pillows sold today.
Common Designs and Features of Knee Pillows
Dimensions for knee pillows vary by brand and model. Most measure roughly 10 inches wide, and between four and six inches thick. They are also much lighter than primary sleeping pillows. The average knee pillow weighs one pound or less.
Common shapes for knee pillows include the following:
- Hourglass: This is the most common shape for knee pillows, as well as the cheapest option in most cases. The hourglass contouring aligns with the natural curvature of your knees for added comfort, which holds both legs in place throughout the night.
- Wedge: Wedge pillows have a triangular or half-moon shape, and are most suitable for back sleepers when placed beneath the knees. However, many side sleepers find they are sufficiently comfortable as well.
- Body: Body pillows are exceptionally wide, and designed to run the length of an adult’s figure. Some people tuck body pillows between their legs, which can result in less pressure on the back and less friction between the knees and legs. Body pillows are not necessarily designed to fit between the knees, but many people utilize them for this purpose. To learn more, check out our Best Body Pillows guide.
Knee pillows are usually made of memory foam or polyfoam, which may be one piece or shredded and contained in a case. They typically have a cover made from cotton or synthetic fibers, such as polyester and/or rayon. Most knee pillows are Medium Firm or Firm. This prevents the knees from compressing the pillow too much, which can reduce support and comfort.
Some knee pillows come with removable knee straps. These straps wrap around the knees to help the legs remain in place throughout the night.
