Types of Knee Pillows

Although knee pillows look pretty much alike, they are available in various types, as it follows:

1) Hourglass Knee Pillow: The most common and the most affordable type of knee pillow is that shaped like an hourglass. Its design prevents your legs from sliding out during the sleep. Additionally, you may either use it between your thighs or move it down to the lower legs, depending on your needs.

2) Strap on Knee Pillow: This type of knee pillow features a strap that you may attach to one of your legs. That prevents the pillow from moving around during the night. What is more, this pillow design is typically longer than the hourglass one.

3) Long Knee Pillow: Although long knee pillows could provide increased support to your lower body, they could prevent you from turning over during your sleep. However, these are perfect for you if you want to cradle your entire body along with the knees.
