A bolster pillow is a long, usually firm, often cylindrical cushion designed to give targeted support to parts of your body—like your back, neck, knees, or legs—while you sleep, lounge, or do yoga.

What is a bolster pillow?

  • It is typically long and narrow , most often tube-shaped rather than square like a regular pillow.
  • Common fillings include cotton, down, or synthetic fiber; some modern versions use memory foam or buckwheat for firmer, shaped support.
  • There’s no standard size, but many are shorter and firmer than a body pillow and often come with a removable cover and zipper.

What is it used for?

People use bolster pillows for:

  • Sleep support: under the knees for back sleepers, between the knees for side sleepers, or along the spine for extra alignment.
  • Pain relief and physiotherapy: to elevate limbs, reduce pressure on joints, and support the lower back or hips during rest or rehab.
  • Yoga and relaxation: as a prop in restorative yoga, under the spine or legs to help open the chest and reduce tension.
  • Décor: as an accent pillow on beds, sofas, or window seats to add structure and a more tailored look.

How is it different from a regular pillow or body pillow?

  • Regular pillow: usually rectangular and softer, mainly for head and neck support while sleeping.
  • Bolster pillow: firmer, cylindrical, focused on targeted support (back, knees, arms) and often decorative.
  • Body pillow: longer and softer, meant to run along most of your body for full-body hugging support, especially for side sleepers and pregnancy.

Simple example

If you sleep on your back and wake up with lower back stiffness, placing a firm bolster pillow under your knees can slightly tilt your pelvis, reduce lumbar strain, and help your spine rest in a more neutral position.
