Where Support Goes When You Sleep on Your Side in Pregnancy

What the sources say

ACOG says it may help to place a pillow between your knees and another under your belly. ACOG adds that you can also try a full-length body pillow for support.

Mayo Clinic suggests placing pillows between your bent knees, under your stomach and behind your back. Mayo Clinic notes that full-length body pillows are also available.

Three places, three guides

2. Under the belly — Supporting Your Belly When You Lie on Your Side
3. Behind the back — Support Behind Your Back When You Sleep on Your Side

Which of our shapes sits where

The sources discuss pillow placement generally. They do not evaluate or recommend Queen Rose products; the section below just maps where each of our shapes physically sits.

An E-shape works from three points of support — belly in front, back behind, knees apart — and leaves one side open.

A full wraparound pillow takes up room. On a U, one side runs the length of your back and the other side sits between your legs.

The Adjustable Contour Body Support Pillow runs along your lower back, follows the curve out past your waist, and its lower section fits between your legs.

The honest part

A pillow supports the position you choose — it does not prevent normal movement. And it's support for how you rest, not treatment for how you feel. For questions about pregnancy sleep positions, follow the guidance of a qualified healthcare professional.
