How to Use a Sex Pillow
A position cushion is a support tool, and like any support tool it works when it is placed correctly and does nothing when it is not. The two mistakes almost everyone makes at first are putting the cushion too far up the back and choosing far too much height. This guide covers placement, height, and the small adjustments that turn a cushion from novelty into something you actually keep using.
Placement: hips, not waist
For a pelvic tilt — the most common use — the cushion belongs under the hips and the base of the glutes, not under the lower back. Placed under the lumbar spine it forces the back into extension, which is exactly the strain most people bought the cushion to avoid.
For reclined and face-to-face positions, the support should run along the torso instead. That is a ramp's job: the slope carries the shoulders and head so the neck is not doing the work.
- Pelvic tilt: cushion under the hips, lower back flat and supported by the mattress
- Reclined: long incline under the whole torso, head supported at the top
- Kneeling: cushion under the torso so the shoulders and neck stay neutral
- Rear entry: cushion under the hips, with a normal pillow available for the head
Start with less height than you think
Height is the variable people get wrong. Two to four inches of lift changes the angle noticeably; a very tall wedge can push the pelvis past a comfortable range and create hip or lower-back strain, especially if either partner has limited hip mobility.
Soft mattresses already sink and add effective angle. If your bed is plush, choose a lower profile than the charts suggest.
Why a bed pillow is not a substitute
Down, fibre, and shredded foam all compress under body weight plus motion, so any angle you set with a bed pillow collapses within moments. That is the entire functional argument for a dense foam cushion: it holds its shape while loaded.
There is also a hygiene difference. Position cushions ship with a moisture-resistant liner between the cover and the foam. A regular pillow has no such barrier, and foam that absorbs moisture is not something you can properly clean.
Comfort and accessibility notes
Many people buy these cushions for accessibility rather than novelty: lower-back pain, hip or knee arthritis, post-surgical recovery, pregnancy, or limited mobility all make unsupported positions uncomfortable or impossible. Supporting the joints that are complaining — knees, hips, lumbar spine — is a legitimate and common reason to own one.
If you have a specific medical condition, recent surgery, or a pregnancy with complications, ask your clinician what positions and angles are safe for you rather than guessing from a product page.
Cleaning and storage
Unzip and machine wash the outer cover on a cool cycle and air dry it; microvelvet does not like high heat. Wipe the inner liner rather than soaking it, and never put a foam core in a washing machine — it will tear and it will not dry.
Store foam shapes flat or upright rather than compressed under heavy objects, which permanently deforms the foam over time.
FAQ
Can I just use regular pillows instead?
You can, and plenty of people do. The trade-offs are that bed pillows compress so the angle disappears, they slide apart, and they have no moisture barrier. If you only want occasional lift, a firmly folded blanket works better than a pillow.
What height should I start with?
Two to four inches of hip lift suits most people. Go lower if your mattress is soft or if either partner has hip or lower-back limitations, and only go higher once you know a modest angle is not enough.
Are these safe during pregnancy?
Support cushions are commonly used for comfort during pregnancy, but which positions and angles are appropriate depends on your stage and your health. Ask your midwife or doctor rather than following a general product recommendation.
