Best for: Side sleepers who want tunable firmness, smaller beds, pregnancy support without a wraparound
The adjustable body pillow — same add-or-remove-fill system as Coop's #1 head pillow, stretched to 54 inches.
Worth itAdjustable fill, so it works through a pregnancy and after it rather than becoming loft-flat in month five.Most body pillows arrive at one firmness and you live with it. Coop's unzips: cross-cut memory foam blended with microfiber that you add or remove until the loft matches your frame and the gap between your knees. Lulltra cover (polyester/bamboo-derived viscose), CertiPUR-US and GREENGUARD Gold certified, machine washable, 100-night trial and 5-year warranty. Straight I-shape rather than a wraparound, so it takes far less bed than a U-shape while still supporting hips and shoulders.

Same adjustable cross-cut memory foam system and Lulltra cover, in a 20×54 bolster. If the head pillow's add-remove-fill approach worked for you, this behaves the same way between the knees and under the arm.
A straight body pillow supports the front of your body and knees while leaving your back open — and takes roughly a third of the bed a U-shape does. Choose the U-shape if you want simultaneous back support; choose this if you share a bed or want adjustability.
Start by removing enough that the pillow compresses to about the width of your knee gap when you lie on your side. Coop ships extra fill deliberately; most people take some out. Keep what you remove — there's no bag included, so use a zip bag.
Coop markets body-pillow support for side sleeping, which is the position recommended in pregnancy, and sells a dedicated maternity edition. This is general comfort guidance, not medical advice — ask your provider about your own positioning.
