Frequently Asked Questions

Everything you need to know about the Knee Pillow.

Find your perfect product

Tap any option:

Knee Pillow™ — knee, hip or lower-back pressure.
Wing Pillow™ — neck/shoulder pain, taller or broader build.
Wave Pillow™ — neck pain & sleeping hot, suits most.
Pregnancy Pillow™ — full-body support.
Honeycomb Mattress Topper™ — firm or lumpy mattress.
Sitting Cushion — back/tailbone pain from sitting.
Pressure Ball™ — muscle knots & trigger points.

Who is it for?

Side sleepers especially — it stops your top leg dragging your hips and spine out of line. It's also a favourite during pregnancy, and for anyone with sciatica, hip pain, knee pain or recovering from surgery who needs to keep their legs supported and aligned.

Does it stay between my knees all night?

Yes — the contoured shape and grippy cover keep it in place instead of slipping out and ending up on the floor like flat foam wedges do.

It's a cooling product

Like everything we make, it's built around our open TPE honeycomb grid to keep you cool. Air flows freely instead of trapping heat between your legs, so you stay comfortable all night.

How firm is it and will it go flat?

Medium-firm and engineered to hold its shape permanently — the interlocking honeycomb springs back every time, so it won't flatten or lose support like a cheap foam pillow.

How do I clean it?

The cover zips off and machine washes on a cold, gentle cycle. The TPE honeycomb is naturally resistant to mould, dust mites and bacteria, so it stays fresh and hygienic.

ErgoSleep Wave Pillow review
Taylor M. Wave Pillow · Melbourne, VIC "Took a couple of nights to get used to, but now I can't sleep on a normal pillow. My neck feels supported the whole night."
ErgoSleep Wave Pillow review
Olivia R. Wave Pillow · Perth, WA "Bought it hoping it'd help with my tension headaches. Three weeks in and they're way less frequent. Wish I'd found it sooner."

Ash B. Wave Pillow · Sydney, NSW "Three months in and it still feels like night one — zero flattening. Neck pain that I'd just accepted as normal is gone."
ErgoSleep Wave Pillow review
Mia R. Wave Pillow · Perth, WA "The cooling is real — no more flipping the pillow at 2am. And my neck stiffness in the mornings has pretty much disappeared."
ErgoSleep Wing Pillow review
Sarah M. Wing Pillow · Sydney, NSW "Side sleeper here. The Wing keeps my neck straight instead of bent all night — I've stopped waking up needing to crack it."
ErgoSleep Wave Pillow review
Jess K. Wave Pillow · Brisbane, QLD "Felt a bit odd the first night, by night three I was sold. Waking up without a stiff neck still feels strange in a good way."
ErgoSleep Sitting Cushion review
Jake M. Sitting Cushion · Sydney, NSW "I'm at a desk 9+ hours a day and my tailbone used to ache by lunch. This cushion sorted it. Take it to the office and back."
ErgoSleep Wave Pillow review
Petra S. Wave Pillow · Hobart, TAS "Was sceptical about the price, but my neck pain is heaps better and I love that I can just rinse it clean. No regrets."
ErgoSleep customer review
Liam D. Honeycomb Mattress Topper · Canberra, ACT "Our mattress was way too firm. One night on the topper and it felt like a new bed — softer where I need it but still supportive, and I'm not overheating anymore."

Game changer for neck pain
I've struggled with morning neck stiffness for years. After two weeks on the Ergo pillow it's basically gone. Best purchase of the year.

My partner bought one first and I was jealous of how well he slept. Got my own and now we both sleep like babies.
