Your pregnancy pillow quickly becomes the most fiercely guarded item in your bed. It balances your hips, takes the weight of your growing bump, and helps you stay settled on your side through the night. But between night sweats, skincare routines and late-night snacks in bed, it doesn't take long for your favourite sleep companion to need a refresh.
Washing a standard pillow is one thing. Cleaning a large, uniquely shaped pregnancy support system is another entirely, and one wrong move in the laundry can turn a well-contoured cushion into a lumpy, deflated mess, leaving you without support right when you need it most.
The good news is that keeping your pillow clean and in good shape is straightforward once you know the rules for your particular pillow.
The Golden Rule: The Cover and the Cushion Are Not the Same Job
Whatever brand of pregnancy pillow you own, the single most useful habit is this: wash the cover, not the cushion.
The cover takes almost all of the surface oils, sweat and everyday grime. The inner cushion sits protected underneath it and rarely needs anything more than an airing. Most of the horror stories, the lumping, the flattening, the pillow that never dries properly, come from putting an inner cushion through a wash it was never designed for.
So before you wash anything, check the care label on your specific pillow. The instructions below cover the common fill types, and then the specifics for your Sleepybelly.
Washing the Outer Cover
-
Unzip and inspect. Carefully unzip the outer casing and slip it off the inner cushion pieces. Check the seams for loose threads or caught edges so nothing tears in the wash.
-
Use a gentle, cool wash. Put the cover through the machine on a delicate cycle using cold to warm water. Hot water is the enemy here. It can shrink fabrics and break down the stretch in specialty blends, which makes the cover a nightmare to slide back on afterwards.
-
Choose a mild, fragrance-free liquid. Pregnancy can make your skin much more sensitive, and heavy perfumes or harsh residues trapped in the fabric right next to your face can be irritating, especially if you're already dealing with nausea.
Cleaning the Inner Cushion (Material Matters)
Before the inner cushion goes anywhere near a washing machine, check what is actually inside it. Different fills need completely different handling.
Poly-Fill and Fibre-Fill Inserts
If your pillow is filled with polyester fibres, it is often machine-safe, though you should still confirm on the label. Top-loading machines with a central agitator can twist and permanently clump the fibres.
-
The right way: Use a large front-loading machine on a gentle cycle.
-
The pro tip: Run an extra rinse cycle so no soap is left buried in the dense centre of the fill.
Memory Foam Inserts
If your pillow uses solid or shredded memory foam, do not put it in the washing machine. Memory foam soaks up water like a sponge, takes days to dry, and the structure breaks down in the process.
-
The right way: Spot-clean surface marks with a damp cloth and a tiny drop of mild detergent, then press the area with a dry towel to lift out the moisture and let it air fully.
Latex Inserts (Including Your Sleepybelly)
Latex is in the same category as memory foam here. The Sleepybelly inner cushions are not machine washable. They shouldn't be soaked, put through a cycle, or tumble dried, and doing so will damage the latex and the shape you rely on.
What you do instead:
-
Wash the covers, as often as you like. The Sleepybelly covers are removable and machine washable on a warm to cold wash. This is the part that gets dirty, so this is the part that gets washed.
-
Spot-clean the cushion only. A damp cloth on the mark, a dry towel to blot, then let it air dry completely before the cover goes back on.
-
Let the fabric do some of the work. The covers are a breathable bamboo blend treated with an antibacterial finish, which is designed to keep things fresher between washes rather than needing constant laundering.
A practical tip a lot of mums land on eventually: buy a second cover. It means you're never without your pillow on wash day, waiting for a cover to dry.
Why Modular Designs Make Laundry Day Easier
This whole process is a good illustration of why large single-piece U-shaped and C-shaped pregnancy pillows can be such a hassle. They often don't fit in a standard Australian home washing machine at all, which turns a simple wash into a trip to the laundromat.
The Sleepybelly Pregnancy Pillow sidesteps that problem. Because the system separates into individual back, bump and knee support pieces, the covers come off in seconds and go into any normal machine load. There is no wrestling a giant ring of fabric back into shape afterwards, which in practice means the covers actually get washed regularly instead of being put off week after week.
Drying: Where Most Pillows Get Ruined
Washing correctly only gets you halfway. Any dampness left sitting inside a cushion or seam is what leads to mould and musty smells.
The Low-Heat Dryer Method
This applies to covers and to fills that are confirmed dryer-safe, not to memory foam or latex cushions. If your label allows machine drying, use a low-heat or air-fluff setting only. High heat scorches synthetic fibres.
The fluffing hack: Drop two or three clean wool dryer balls into the drum alongside a fibre-fill cushion. As the dryer turns, they bounce against the fill and break up clumps, which helps restore its loft.
The Air-Drying Method
For covers, latex cushions and anything you're unsure about, air-drying is the safe choice. Lay the item flat on a clean drying rack in a well-ventilated spot. Avoid pegging full-sized body pillows by their corners on the line, as the weight of the water pulls the fabric out of shape permanently.
Keeping It Fresh Between Washes
You don't need a full wash cycle every week to keep your sleep space feeling clean. A few small habits stretch the time between washes considerably:
-
Air it out. Every time you change your sheets, pull the covers off and let the cushions air for half an hour before remaking the bed. It is the simplest thing on this list and makes the most difference.
-
Daily fluffing. Give your support pieces a quick shake each morning to redistribute the fill and stop pressure points flattening out over months of use.
-
A little sunlight. Sitting your pillow pieces somewhere airy and bright for an hour helps freshen them up. Keep it brief and avoid long stretches in harsh direct sun, which can degrade fabrics and latex over time.
The Bottom Line
A pregnancy pillow is one of the few things you'll use every single night for months, so it's worth looking after properly. Wash the covers in cool water, spot-clean the cushions rather than soaking them, and air-dry anything you're not certain about. With a modular pillow, that whole routine takes minutes, which means your sleep setup stays fresh and properly supportive right through to your due date.

Frequently Asked Questions
How often should I wash my pregnancy pillow cover?
Because the cover is against your skin every night, aim to wash it as often as your bed sheets, so roughly every one to two weeks. The inner cushions don't need that treatment. Airing them regularly and spot-cleaning any marks is enough.
Can I dry clean my pregnancy pillow to save time?
Generally no. The solvents used in standard dry cleaning can degrade synthetic fills and break down foam and latex structures, and the chemical smell tends to linger deep in the filling afterwards, which isn't what you want next to your face all night.
Why did my pillow come out of the wash completely lumpy?
Lumping happens when fill gets saturated and clumps under pressure, or when soap hasn't rinsed out fully. For fibre-fill pillows you can often recover it by re-washing with no detergent, running an extra spin to pull out the water, then tumble-drying on low with dryer balls. For latex or memory foam cushions, unfortunately this damage is usually permanent, which is why they shouldn't go in the machine to begin with.
Is it safe to use fabric softener on the pillow cover?
Best to skip it. Fabric softeners leave a thin coating across the fibres, and that coating reduces the breathability and moisture-wicking that makes a bamboo blend cover comfortable in the first place. If you're already dealing with night sweats, softener works against you.
