A good waterproof mattress protector is your mattress’s best friend. It shields against accidents, spills, sweat, and everyday wear. But how long should one actually last before it needs replacing?
If you’re wondering whether your current protector is still doing its job, or you’re considering investing in a new one, this blog will walk you through how long a quality waterproof protector should last, and how to get the most out of it.
So, How Long Does a Waterproof Mattress Protector Last?
On average: 1 to 2 years of regular use.
But that can vary based on:
- How often it’s used
- How it’s washed and dried
- The quality of materials and construction
- Whether it’s used with other layers (e.g. bed pads)
Lower-quality protectors made with stiff plastics or vinyl may break down after a few washes. In contrast, Staydry protectors, made with soft, breathable fabric and our signature Breathe Cell™ waterproof layer, are designed to last well over 100 washes often 2+ years with good care.
What Causes a Protector to Wear Out?
Just like your favourite sheets or pyjamas, even the best mattress protector will eventually show signs of wear.
Common causes of wear and tear include:
- High-heat washing or tumble drying
- Use of bleach or fabric softeners
- Frequent exposure to heavy moisture (e.g. incontinence, spills)
- Physical friction from tossing, turning, or bed mobility aids
- Age and material breakdown over time
Signs it might be time to replace your protector:
- It’s no longer waterproof (leaks reach the mattress)
- You notice cracking or peeling on the backing
- It feels stiff, noisy, or uncomfortable
- There’s persistent odour or staining even after washing
- The elastic edges no longer hold firmly to the mattress
How to Make Your Waterproof Protector Last Longer
With a little care, you can maximise the lifespan of your protector and keep your mattress safe night after night.
1. Follow the washing instructions
Staydry protectors are machine washable, but we recommend:
-
Cold to warm wash (30–40°C)
-
Gentle detergent
-
No bleach, fabric softener, or ironing
-
Line dry or tumble dry low
2. Use a mattress pad or fitted sheet over the top
This protects the protector ironic, but true. A cotton or bamboo sheet helps reduce direct wear.
3. Rotate or change out protectors regularly
Having two or more protectors in rotation allows them to rest between washes, prolonging the life of each.
4. Wash only when needed
Unless there’s been an accident, you don’t need to wash it weekly. Every 2–3 weeks is fine for most.
Why Material Quality Matters
Not all waterproof protectors are built the same.
Cheaper brands may use:
- Vinyl or PVC (hot, sweaty, prone to cracking)
- Plastic-like backings that rustle loudly
- Thin seams or poor stitching that break down quickly
In contrast, Staydry mattress protectors are:
- Made with Breathe Cell™ breathable waterproof membrane
- Soft, quilted, and noise-free
- Machine washable, fast-drying, and durable
- Built to handle real-life use — from kids and carers to hot sleepers and everything in between

FAQs
Q: Should I replace my protector after every accident?
No, Staydry protectors are designed to be washed and reused many times. Just follow the care guide and dry it properly after washing.
Q: Will the waterproof layer wear off?
Eventually, yes. But with proper washing and no high heat, our Breathe Cell™ layer maintains its performance for 1–2+ years of regular use.
Q: Do different types of protectors last longer?
Yes, quilted protectors or those with natural fibres (like bamboo) tend to wear more slowly than thin, plastic-coated versions.
When cared for properly, a waterproof mattress protector can easily last 1–2 years or longer. And when it’s protecting a $1,000+ mattress? That’s a no-brainer investment.
At Staydry, we believe in building high-quality, breathable protectors that last. Whether you’re managing bedwetting, incontinence, or just want to extend the life of your bed, our protectors are made to go the distance with you.
