Relvay makes a pregnancy pillow. We also tell you below when you should not buy one.
The short answer
Most connectors that keep letting go are fitted the wrong way, mixed with parts from another version, or worn at the fastener. Identify your connector, check every part belongs to the same set, then fit it the way your version's instructions show.
- Name it: strap, zip, clip, snap or hook-and-loop.
- Match it: same set, same version.
- Do not add belts, ties or your own straps.
Every turn, the two halves drift apart
A two-part pillow only holds as well as the thing joining it. When that connection lets go, you lose the support on one side every time you move.
3:05 a.m.
I was 30 weeks with a two-piece pillow, one part for my bump, one for my back, joined in the middle. Every time I turned over, I felt the back part slide away. By morning they were at opposite edges of the bed and I was in the gap.
Jordan watched me reattach it for the fourth night in a row and offered to fix it with one of his belts around me and the pillow. I almost said yes. I was that tired.
"The fact that you can strap the belly support pillow to the back support pillow is essential to why this works so well. Everything stays where you put it."Amazon review of a two-part pregnancy pillow
When the connection works, you forget it exists. When it does not, it is the whole problem.
Why do pregnancy pillow connectors come apart?
Usually for one of four reasons: the connector is on the wrong way, the parts come from different sets or versions, the fastener is worn or clogged, or the gap is set wider than your body needs.
Wrong way roundA strap fitted upside down, or into the wrong slot, holds at bedtime and slips once your weight shifts.
Mixed partsA strap from one version may not grip a cushion from another, even if it looks close.
Worn fastenerHook-and-loop fills with lint and hair. Zips and clips can stop closing fully.
Many two-wedge pillows use a hook-and-loop strap. Delta Children, for example, describes its wedge pillow as having a built-in Velcro connector that lets you change the distance between the wedges. That design depends on the two sides meeting flat and clean.
Which connector do you have, and what should you check?
Name your connector first, because each one fails in its own way. Then check the one or two things that matter for that type.
| Connector | Check | Sign it is the fault |
|---|---|---|
| Hook-and-loop strap | Both sides meet fully and flat; hook side free of lint | Peels apart with a light tug |
| Zip between parts | Teeth fully closed to the end; slider not split | Opens from the middle |
| Buckle or clip | Clicks closed; both halves the same size and style | Pops open under weight |
| Snaps | Each snap fully pressed; pairs lined up | One side holds, one side does not |
| Strap through pockets or loops | Strap in the right pocket and fully through | Strap slides out of one end |
| Sewn-in strap | Stitching at both ends intact | Strap pulling away at the seam |
If stitching is pulling away or a fastener is broken, stop adjusting and contact the seller. That is a part problem, not a setup problem.
Do all your parts belong to the same set?
Check that every piece came in the same order or the same box. Hand-me-down and secondhand pillows are often a mix of two sets, and versions of the same pillow can change.
- Lay out every piece: cushions, strap, any small pillow, covers.
- Compare them to the photos on your order or the listing for your version.
- Look at the labels on each piece. Do they show the same name, size or code?
- Check the fastener on both sides is the same kind: same width, same clip, same zip size.
- Find your instructions, or ask the seller for the ones that match your version.
If one part does not match, ask the seller for the correct part rather than making it fit.
Which way round should it go?
Fit it the way your version's instructions show, and test it before you lie down. A connector that runs under you should usually lie flat with your weight resting on it.

- Find the top side of each cushion. Labels or seams often show which way is up.
- Lay the connector flat, not twisted or folded over, in the slot or pocket the instructions show.
- Close it fully. Press hook-and-loop along its whole length, run a zip to the end, listen for a clip to click.
- Set the gap to fit your body, not at its widest.
- Test it by kneeling on the bed and pulling the two parts gently apart. If it opens, refit before you lie down.
Do not tie the pillow to yourself, add belts or extra straps, or swap in fasteners that did not come from the maker. You need to be able to move and get up freely, and a homemade fix can also end help from the seller.
What should you send the seller?
Send a photo of every part laid out, a close-up of the connector on both sides, and a short video of it coming apart. Ask for the right part for your version.
A message you can copy: "Order [number]. The [connector type] between the [part] and the [part] comes apart when I turn. I have checked it is fitted as the instructions show. Photos of all parts and a short video attached. Do these parts belong together, and can you send the correct or replacement part?"
Violet laid everything out on the floor before saying yes to the belt. The strap had the hook side on top. Flipped over, with the lint picked out of it with a comb, it held through the night. Jordan kept his belt. She kept the sleep.
Frequently asked questions
Why does my pregnancy pillow keep coming apart?
Usually the connector is fitted the wrong way, the parts come from different sets or versions, the fastener is worn or full of lint, or the gap is set too wide. Check those in order before adjusting anything else.
How do I make hook-and-loop on my pillow grip again?
Pick lint and hair out of the hook side with a comb or your fingernail, then press both sides together along their full length. If it still peels apart easily, ask the seller about a replacement part.
Can I use a belt or extra strap to hold my pregnancy pillow together?
No. Do not tie the pillow to yourself or add belts and straps. You need to be able to move and get up freely, and homemade changes can end help from the seller.
Can I mix parts from two pregnancy pillows?
Only if they are the same model and version. Straps and fasteners often differ between versions even when they look alike, which is a common reason connectors let go.
What should I send the seller about a connector problem?
Photos of every part laid out, close-ups of the connector on both sides, a short video of it coming apart, and your order number. Ask whether the parts belong together and for the correct part.
