The infinite pillow is a soft, figure‑eight cushion that can be looped and folded into many shapes; for travel it reduces neck pain by supporting the head in flights and car rides—one frequent flyer I know uses it on 6‑hour trips to avoid waking with a stiff neck, and many models measure about 20–28 inches around the loop so they’re compact enough for carry‑on bags. For sleep, the pillow works as a lightweight body or knee bolster that improves spinal alignment; a common use is tucking it between the knees (about 6–8 inches thick when folded) to reduce hip and lower‑back pressure for side sleepers, which physical therapists often recommend to ease chronic low‑back discomfort.

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.
