Cotton Sateen Fitted Sheets Tailored for Australian Mattresses
Our fitted sheets are cut for Australian mattresses in two depths, standard 35cm and deep sided 43cm, so corners stay anchored instead of pulling free overnight. Made from long staple cotton sateen, each sheet is French seamed and fully elasticated for a secure fit that becomes softer with every wash.
Designed in Australia
Which depth do you need?
Measure once, choose correctlyMeasure from the base of the mattress to its highest point. A tape measure held flat against the side gives the truest reading.
If your bed has a pillow top or a mattress topper, include it in the measurement. This is the step most people miss, and the usual reason a fitted sheet pulls loose at the corners.
Up to 35cm, choose the standard fitted sheet. Anything deeper, or any mattress with a topper, is best suited to the 43cm deep sided fitted sheet.
Our Bed Linen Size & Fit Guide explains measuring in more detail, and our Australian Bedding Sizes page lists standard mattress dimensions for every size.
Two depths.
King Single to Super King — French seamed, fully elasticated
Cut for standard Australian mattresses up to 35cm deep. The smooth sateen surface sits cleanly under the body of the bed, while French seams enclose every raw edge for a finish that withstands years of regular washing.
| Mattress depth | Up to 35cm |
| Sizes | King Single, Double, Queen, King |
| Fibre | 100% cotton sateen |

Made for deeper mattresses, pillow tops and beds with mattress toppers. The additional depth lets the sheet tuck securely beneath the mattress, with full elastication holding tension evenly around all four sides.

Why fitted sheets come loose
The physics of pocket depthMost fitted sheets don't come loose because the elastic is worn out. They come loose because the pocket is too shallow for the mattress. Once the pocket depth is exceeded, the elastic sits against the side of the mattress instead of curling underneath it. From there, every movement lifts the corners a little further until the sheet comes away.
The fix is not a tighter sheet in the same size. It is a pocket deep enough to clear the mattress and anchor beneath it, which is why we cut two depths rather than one. If your sheet keeps coming off, measure your mattress with its topper in place and compare it against the two depths above.

Frequently asked
Measure your mattress from the base to its highest point, including any pillow top or mattress topper. Up to 35cm suits the standard fitted sheet. Deeper mattresses, and any bed with a topper, suit the 43cm deep sided fitted sheet.
Yes. The 43cm deep sided fitted sheet is made specifically for pillow top mattresses, deeper profiles and beds with mattress toppers. Full perimeter elastication holds it securely beneath the mattress so it stays in place overnight.
The standard 35cm fitted sheet comes in King Single, Double, Queen and King. The deep sided 43cm fitted sheet comes in Queen, King and Super King. Dimensions for each size are listed on our Australian Bedding Sizes page.
Both depths are elasticated around the entire perimeter, not just the corners. The elastic draws the sheet beneath the mattress on all four sides, so it holds its position rather than pulling loose at the corners.
A French seam encloses the raw edges of the fabric inside the seam itself, giving a clean internal finish and a stronger join that withstands regular washing. Read more in What Tailored Fit Actually Means.
100% cotton sateen, woven from long staple cotton for a smooth, breathable hand feel with a subtle sheen. The cotton is OEKO-TEX and REACH certified, and the sateen surface becomes softer with washing.
