How to put on a mattress protector (and stop it sliding)
A mattress protector is one of the easiest ways to help keep your mattress clean, fresh and protected from everyday spills, stains and wear. But if it isn’t fitted correctly, it can bunch up, move around during the night or even affect how comfortable your bed feels.
Whether you’ve just bought your first mattress protector or you’re wondering why yours keeps slipping, this guide explains exactly how to put one on, how to keep it in place and how to choose the right fit.
Why use a mattress protector?
A mattress protector creates a protective barrier between you and your mattress. Depending on the type you choose, it can help:
-
Protect against spills and stains
-
Reduce everyday wear and tear
-
Keep your mattress fresher for longer
-
Help prevent dust, dirt and allergens building up
-
Add an extra layer of comfort
Unlike a mattress topper, a mattress protector is designed to protect your mattress rather than dramatically change how it feels.
How to put on a mattress protector
Fitting a mattress protector is quick and easy.
1. Remove your bedding
Take off your duvet, pillows and fitted sheet so your mattress is completely exposed.
2. Check the size
Before fitting your protector, make sure it’s the correct size for your mattress.
It should match both:
-
Length and width
-
Mattress depth
A protector that’s too large is more likely to wrinkle and slide, while one that’s too small can be difficult to fit and may put unnecessary strain on the elastic.
3. Position the protector
Lay the protector over the mattress with the quilted or soft side facing upwards (if applicable).
If your protector has elasticated corners or a fitted skirt, line these up with each corner of the mattress.
4. Secure each corner
Start by fitting one corner, then move diagonally to the opposite corner before fitting the remaining two.
This helps distribute the fabric evenly across the mattress.
Once fitted, gently smooth the protector over the surface.
5. Replace your fitted sheet
Finally, place your fitted sheet over the mattress protector as normal.
Your protector should now sit securely underneath your bedding without bunching or moving.
Choosing the right fitted sheet can also help keep your mattress protector in place. At Soak&Sleep, we offer both standard fitted sheets and deep fitted sheets to suit a range of mattress depths, helping you to achieve a smooth, secure fit.
How to stop a mattress protector from sliding
If your protector keeps moving during the night, there are several possible causes.
Choose the correct size
The most common reason for slipping is simply using the wrong size.
Always choose a protector designed for your mattress dimensions, including its depth.
Check your mattress depth
Modern mattresses vary significantly in depth.
If the fitted skirt is too deep, there won’t be enough tension to hold it securely in place.
If it’s too shallow, it may pull off the corners.
Smooth out wrinkles
Before putting your fitted sheet on, smooth the protector across the mattress.
Removing wrinkles helps prevent bunching once you’re lying on the bed.
Fit your sheet correctly
Your fitted sheet also helps keep the protector in place.
A well-fitting sheet creates gentle pressure that helps prevent movement overnight.
Replace worn protectors
Over time, elastic can naturally lose some of its stretch.
If your protector has become loose after years of use, replacing it may help improve the fit.
Can you put a mattress protector under a mattress topper?
Yes. If you’re using both, the recommended order is:
This protects the mattress itself while allowing you to enjoy the extra comfort of the topper.
Can you use a mattress protector on every bed?
Absolutely. Mattress protectors are suitable for:
-
Standard mattresses
-
Pocket sprung mattresses
-
Memory foam mattresses
-
Hybrid mattresses
-
Children’s mattresses
Simply choose the correct size and depth for the best fit.
How often should you wash a mattress protector?
Most mattress protectors should be washed every one to two months, or sooner after spills or accidents.
Always follow the care label instructions, as washing temperatures vary depending on the material and whether the protector is waterproof.
