Top 10 Best Knee Pillows in 2021 – Reviews with Buying Guide


Knee pillows are placed between the knees for added sleeping comfort. These pillows act as a cushioning buffer to ensure your knees don’t rub each other. People with chronic back, leg and spine conditions find this type of pillow very important. Also, you can as well use it if you’re a side sleeper. But, not all knee pillows are right for you. The specialty knee pillows feature an ergonomic design to conform to the contours of sleeper’s body. Here is a carefully formulated review of the best knee pillows.

Buying Guide for Knee Pillows

Knee pillows come in different shapes, design, and materials. As a summary, here are the factors to consider when buying knee pillows.

  • Bearable Weight: Depending on your body weight, you may need to consider the thickness of the knee pillows.  Well, heavier people need to use thicker pillows. The opposite applies to lighter people. With this, you need to understand that the thickness of different knee pillows can vary overwhelmingly.  So, this consideration will help you in making the right judgment.
  • Are You Expectant? Pregnant women tend to sleep on their sides to eliminate the strain of carrying extra weight. Straight pillows or hourglass-shaped knee pillows can be a splendid choice of r side sleepers. As well, a second wedge pillow under the knees can offer extra support for added comfort.
  • Is it premium memory foam material? There is no doubt that memory foam is the best material for pillows and mattresses. However, if you naturally sleep hot, you need to be sure that you sleep comfortably without feeling overheated. In this regard, you also need to examine the case material. So, a breathable fabric cover is indeed the best.
  • Design: Multi-layer design is the best for knee pillows. Top quality knee pillows feature several layers for added functionality. They feature a firm layer as the core and top layer features a softer foam material. Furthermore, memory foam tends to change firmness as the temperature rises or decrease. Therefore, those who naturally sleep hot have an added advantage. The pillow becomes softer when warmth increases and hardens when the temperature lowers.
  • Ease of washing: You also need to see whether the cover of the pillow is washable. If it is, you still need to look at whether the design features a zipper opening. This allows you to easily remove the cushion for easy cleaning. In most of cases, case fabrics are machine washable and you won’t experience hassles in cleaning your knee pillow.
  • Do you move your legs around while sleeping? This is an important consideration because an hourglass-shaped knee pillow can shift and end up not helping you. For this reason, some models feature a removable strap for securing the pillow in the correct position.
