An intimacy pillow is a firm, specially shaped pillow that helps support your body during sex by changing the angle of your hips, back, or legs. For example, placing it under the hips can lift the pelvis, which may make penetration easier, reduce strain on the lower back, and help both partners stay more comfortable. It works by giving your body a stable position instead of letting you sink into a soft mattress or regular pillow.

How to Wear an Infinity Pillow: Easy Steps for Comfort Anywhere An Infinity Pillow is a soft, loop-shaped travel pillow that has no beginning or end. It looks like a thick scarf but works like a pillow for your neck, back, and head. You can wear it in many ways, and it helps you sleep better on planes, trains, cars, or even at your desk. The pillow is made of bamboo fabric and microfiber filling that is soft, breathable, and machine washable.

Sex pillows come in different shapes, and each one changes comfort by changing body angles. The most common types are wedge pillows, ramp pillows, modular sets, positioning blocks, donut or cutout pillows, inflatable pillows, and specialty support pillows. For example, a wedge pillow lifts the hips to help reduce lower-back strain, while a ramp pillow supports the upper body during reclined positions. A wedge pillow is usually triangle-shaped and made to raise the hips or pelvis.

What Is the Prim Pillow Used For? The Prim pillow is a specially designed sex pillow made to make partnered sex more comfortable and pleasurable. Unlike regular pillows, it uses patent-pending dual-density memory foam and a washable linen cover to support your body during intimacy. It’s not meant for sleeping—it’s built specifically for the bedroom to help couples enjoy better positions and less pain. One main use of the Prim is elevating your hips to create better angles during sex.

Get Set Up with Data-Driven Details A sex pillow can raise the hips by 2 to 4 inches depending on the model, which changes the angle of penetration and friction. In a study-like approach, users report that elevating the lower back or hips by this amount can increase stimulation for the receiving partner and improve G-spot or P-spot contact for some positions. For example, in practice sessions with a firm mattress, users found that placing the thicker end under the hips reduced sagging and allowed for more consistent pressure over a 5–10 minute play window, compared to a flat surface.
