The question is, can a wedge pillow cause back pain? The answer is… if used incorrectly, yes. To stop back pain caused by a wedge pillow, let’s go over the best way to position your pillow so you wake up feeling better, not worse!
Why your wedge pillow may be causing back pain
One reason your wedge pillow may be causing back pain is if it is positioned incorrectly. Unfortunately, many companies sell wedge pillows using models that are positioned incorrectly on the wedge pillows. This misleads you, the customer, and can lead to pain and discomfort.

The correct position of your body on a wedge pillow is as follows:
- Neck pillow positioned on top of the wedge
- Wedge ends in lower back, level with the top of your iliac crest (or the top of your hip bone)
- Gltues and hips should rest on the mattress
Maintain spinal posture
If your positioning is correct, and you still think your wedge pillow is causing back pain, it could be that your spine does not like the introduction of the angle to your sleep position. Sleeping with your torso on a wedge pillow does increase the pressure on your lower back. If you have any sort of back issues, this angle could exacerbate them.
An easy way to combat this is to sleep with your legs resting on a leg wedge pillow. Sleeping with your legs elevated takes the pressure off your lower back. Elevating your legs will gently rotate your hips posteriorly. This eliminates tension in your back muscles.
Without a leg wedge, gravity has a higher pull on your back. The pull of gravity on your lower back could be the cause of your back pain. Sleeping with your legs elevated on a leg wedge drastically reduces the effects of gravity on your back. Eliminating the effect of gravity will make a huge difference in making sure you wake up without back pain.
A wedge pillow puts your body in a new position
Keep in mind, anytime you start sleeping in a new position, it takes your body time to get comfortable. For instance, if your body is going from sleeping flat to sleeping at an angle, give yourself time to adjust. Give your bones, joints, and body, 30 days to adjust to your new pillow.
