A back pillow for a bed is often referred to as a backrest pillow or a lumbar pillow. Regardless of what you call them, these pillows help to provide extra support for your lower, or lumbar, spine, encouraging better posture and alignment for resting and relaxing in bed. By providing extra comfort and support, you may be less likely to experience lower back pain when using it.

A backrest pillow can be a helpful or even essential addition to your bed, or for use around your home. A back support pillow for bed helps create a much more comfortable resting and sleeping environment, while also promoting better posture and alignment—now that’s pretty good. A backrest pillow is also used as a “reading pillow,” for those that want extra comfort and need additional support while they sit up and read a book in bed.
 
The Casper Backrest Pillow utilizes an ergonomic teardrop design, along with supportive inner foam and outer foam layers. Together, this makes for a perfect pillow that is equally soft and supportive.

If you want proper posture, healthy spinal alignment, and enjoyable rest, then you absolutely should try a lumbar pillow.
 
Using a lumbar support pillow either while sitting or lying in your bed can help with your spine’s alignment, and also provide you with a more restful, relaxing experience.

A backrest pillow for bed should be thick enough to properly support your lower spine, but not so thick that the pillow ends up pushing your spine too far forward and causing further discomfort. Because of the natural curvature of your spine, it should be thicker at the base, where it sits behind your lumbar, and thinner at the top, where it reaches your mid, or thoracic, spine.
 
The Casper Backrest Pillow ranges in thickness from 2” to 5” due to its ergonomic teardrop design, which matches with your body’s proper spinal alignment.

This depends in part on what is the most comfortable position to properly support your lower back. Most people use their lumbar pillow for the bed by placing it upright against their headboard or wall, then sitting with their back against it. This is perfect for reading or watching television while resting in bed.
 
However, you can also use your lumbar support pillow as a standard pillow, with the slimmer end closest to you. Some people also put them under their knees while laying flat on their back as a way to relax and release the back muscles. These both provide a different, but equally comfortable, type of additional support.
