The short answer: The ComfiLife is the most widely used sleeping lumbar pillow and doubles as a knee bolster. The RESTCLOUD has two removable inserts for three heights. The QUTOOL is the budget two-height option. The Cozyhealth Heated is for warming up before sleep. Start low: too tall a pillow arches the back.

How to use one
Lie on your back on your usual mattress and slide a hand under the small of your back. If there is a clear gap, a lumbar pillow can fill it. Place it just above the belt line, flat side down, and start with the lowest height. The goal is light contact, not a push. If your back feels arched or you wake stiffer, take height out or move the pillow under your knees instead.
Side sleepers rarely need a lumbar pillow; a pillow between the knees does more. Stomach sleepers should skip it entirely.

When a pillow is not enough
If you need a lumbar pillow because your bed sags in the middle, the bed is the problem. See best mattress for lower back pain and, for a cheaper fix on a sound bed, toppers.
Before you order: reader questions
Should I sleep with a lumbar pillow?
If you sleep on your back and feel a gap under your lower back, it is worth trying. Start low and stop if it makes you stiffer.
Is it better under the back or under the knees?
Many people with lower back pain find a pillow under the knees more comfortable. Try both.
Are heated lumbar pillows safe to sleep on?
Use them as the maker instructs, with auto shut-off, and avoid sleeping on a heat source all night, especially if you have reduced sensation.
This page is general shopping information, not medical advice. If your back pain is new, getting worse, or keeps you awake whatever you sleep on, talk to a clinician before you spend money on a bed. Full disclaimer.
