What is the OrthoCore™ Seat Cushion?

A contoured memory foam cushion designed for everyday sitting — desk work, driving, dining chairs and long periods of seated work. It measures 43cm × 34cm, has a non-slip base and a removable, machine-washable cover.

What is the OrthoCore™ Lumbar Support Pillow?

A full-height memory foam back support (44cm × 38cm × 12cm) with a bamboo charcoal foam core. Adjustable straps fasten it to most office chairs and car seats so it stays where you set it.

What is the OrthoCore™ Knee Pillow?

A contoured, slow-rebound memory foam pillow designed for comfortable side sleeping. It sits between the knees and thighs, measures 36cm × 25cm (8.5cm high at the dip, rising to 13.5cm) and comes with a detachable strap and a removable, machine-washable cover.

Which product is right for me?

If you spend long hours sitting — at a desk, driving or commuting — the Seat Cushion supports you from below and the Lumbar Support Pillow supports your back. Buying both together applies an automatic A$19.95 saving at checkout. If you sleep on your side, the Knee Pillow is designed for that.

Will the seat cushion fit my chair?

At 43cm × 34cm it suits most office chairs, car seats and dining chairs. The base grips the seat so it stays in place as you get in and out.

Does the knee pillow stay in place overnight?

The contoured shape is designed to nest between the knees, and the strap keeps it with you when you roll over. The strap detaches if you prefer to go without it.

Are these medical devices?

No. OrthoCore™ products are designed for everyday comfort and ergonomic support. They are not medical devices and are not intended to diagnose, treat or cure any condition. If you have a health concern, please speak to a qualified professional.

Order tracking

Where is my tracking number?

You'll receive it by email once your order is dispatched. See our Track Your Order page for full details.

My tracking hasn't updated — is something wrong?

Tracking can take up to 72 hours to activate, and parcels sometimes sit without a scan while moving between transit hubs or clearing customs. If there's been no movement for 7 days, email us with your order number and we'll chase the carrier on your behalf.

Tracking says delivered but nothing arrived.

Check your letterbox, around the property, with neighbours and at your local collection point first — parcels are often left in a safe place or held for pickup. If it still can't be found, contact us within 14 days and we'll work with the carrier to resolve it.

Returns & guarantee

What is the 30-day comfort guarantee?

Try it in your everyday routine. If it isn't the right fit for you, email us within 30 days of delivery with your order number and you're covered by our guarantee. Full terms are in our Refund Policy.

What if my item arrives damaged?

Send us a photo within 7 days of delivery and we'll replace it at no cost or refund you in full — your choice.

Can I exchange for a different product?

Yes. Email us and we'll arrange it, charging or refunding any price difference.

How long do refunds take?

Approved refunds are issued within 2 business days. Your bank or card provider may take a further 5–10 business days to show it.

Product care

Can I wash the covers?

The seat cushion and knee pillow covers zip off and are machine washable — wash cold and air dry. For the lumbar support pillow, wipe the cover clean with a damp cloth. Spot clean foam cores only — don't submerge them in water.

The foam feels firm out of the box — is that normal?

Yes. Memory foam is compressed for shipping. Allow 24 hours for it to fully expand before judging the firmness.

International orders

Will I pay duties or taxes?

Depending on your country's import thresholds, duties or taxes may apply to international orders. Where these are collected at checkout, no further charges apply on delivery. Where they are not, they are the recipient's responsibility. We declare all shipments accurately.

What currency are prices in?

Prices are shown in the currency of your selected market. Your total is confirmed at checkout before payment.
