Discover the Power of a Better Night's Sleep

If your king single mattress could talk, it’d tell you to buy a king single mattress protector. Protectors keep things hygienic, cushy and spill-proof without interrupting your sleep. Fresher sleeps, no weird stains, and a mattress that still feels young enough to remember its warranty. Choose waterproof, choose quilted, choose whatever makes your bed feel breezy.

Why Buy a King Single Mattress Protector from Sleepy’s?

Because Sleepy’s understands real-life sleep, not the no-spills kind. Our king single mattress protectors are made in Australia from durable, breathable fabrics to handle everything life throws at them. From late-night study snacks to morning coffee in bed, your mattress stays clean and comfy.

We’ve done the choosing for you, so you won’t get stuck in a king single mattress cover deep-scroll vortex. This is protection with purpose, backed by Sleepy’s sleep expertise and endorsed by humans who’ve seen every bedroom blunder.

How to Choose the Right King Single Mattress Protector

Mess potential: High? Go waterproof. Low? Standard or quilted is ok.

Allergies in the house? Choose hypoallergenic or fully encased protectors that keep dust mites and nasties out.

Sleep temperature: Run hot? Pick breathable natural fibres like cotton or bamboo, or go for tech fabrics with cooling properties.

Mattress depth: Measure before you buy.  King single mattresses can vary in height; get the right depth.

Comfort style: Want extra softness? Go quilted. Prefer sleek and simple? Choose smooth, fitted styles. 

Shop by Feature / Type

  • Waterproof Protectors: For spills, sweat and snack disasters.
  • Hypoallergenic Protectors: Allergen-friendly for sensitive sleepers.
  • Quilted/Extra Comfort Protectors: Added softness and cushioning for a plush surface.
  • Encasing or Fitted Protectors: Go easy fit, or encase your mattress in maximum 360 protection.

Frequently Asked Questions


Can I use a mattress protector with any King Single mattress?

Absolutely. A king single mattress protector is designed to fit most standard king single mattresses, including deeper styles. Just check the depth if you have a topper or extra-plush setup.


How do I clean my mattress protector?

Check the care instructions first, but most mattress protectors are machine-washable. If so, just peel it off, toss it in, and you’re good to go. Wash every 1–2 months or more often if you’ve got kids, pets, or are prone to spilling your morning coffee.


Will a protector affect mattress comfort or feel?

Only in a good way. A king single mattress protector is made to be soft, breathable and silent. No crunchy layers or plastic rustling, just extra freshness and comfort.


How long does a mattress protector last?

With proper care, a quality king single mattress cover can easily last a few years. The lifespan depends on how often it’s washed, the materials used, and what it’s up against (spills, pets, midnight snacking).


Are mattress protectors waterproof or stain-resistant?

Sleepy’s stocks both. The king single waterproof mattress protector is your go-to for serious backup—think spills, sweat and small kids. Stain-resistant options offer lighter protection with more airflow and breathability.

Frequently Asked Questions

How Long Until My Order Is Delivered?
Our mattresses are Australian made and when you order online, chances are they are yet to be made by our Australian manufacturers! Due to the nature of bulky goods and potential construction time, delivery times will vary depending on the product and availability. If you’re purchasing in-store, we will advise you of an estimated delivery time, at the time of purchase. If you’re purchasing online, a local Sleepy’s consultant will be in touch to confirm a delivery date. Mattress and standard bases could take up to 7-10 business days. Customised drawer bases and bedheads between 15 and 21 business days.
What Happens Once I Place an Order?
Online – once your order has been received and payment confirmed, one of our consultants will make contact with you. This may be in the form of email or telephone. Please check your “junk” mail after your order has been placed just in case our email ends up there by mistake! The consultant in store will let you know they have received your order and will make arrangements to have your new mattress made for you. They will also provide you with regular updates as required to advise delivery details and time lines. This could be through email, SMS or telephone, you get to select which method suits your lifestyle. In Store – our consultants will provide you with information on delivery time lines at the time of your purchase. If they need to order the product from our suppliers they can provide you with regular updates as required. This could be through email, SMS or telephone, the choice is yours, just let your consultant know at the time of purchase.
Is Old Mattress Removal Available?
Yes, Sleepy’s offer free mattress removal at no extra cost. When we deliver your new mattress, for both in store and online mattress purchases, our team will remove your old mattress at no charge! We do reserve the right in some cases, where the health and hygiene of our staff or contractors may be at risk, to negotiate an alternate arrangement for disposing of your mattress. During COVID-19, changes may apply to delivery schedules and free old mattress removals at this time. If you are purchasing online, we will confirm your delivery before processing your order. If you are making your purchase in one of our Sleepy’s showrooms, our teams in store will advise you of the current delivery protocols. Sleepy’s use independent contractors for delivery services to our customers and during this time we want to support these small business owners and our customers to ensure safety for all. Please note, bases and other bedroom furniture are not part of our Free Old Matt Removal offer. This service is available in some stores at an additional charge. Please contact your closest Sleepy’s store for more information.
Will I Receive Advance Notice Before Delivery?
Yes, you will be contacted prior to delivery via SMS, email or phone call.
What Do I Need to Know Prior to My Order Being Delivered?
If Sleepy’s are delivering a new mattress (and/or base) to your home, we will contact you beforehand to provide guidelines to help arrange a smooth transition. As these products are large and heavy, it is recommended fragile, valuable and cherished possessions are tucked away and a clear pathway to the room be created.
Can I Change or Cancel My Order After I Have Placed it Online or In-Store?
Cancellation of orders will attract an administration fee equal to 20% of the total value of goods if your order has been placed with the manufacturer. You are not entitled to a refund if you simply change your mind. Order changes can be managed through the store. We always want to provide you with the most suitable outcome possible and will work with you to achieve this. Sleepy’s offer 60 Night Comfort Exchange on the occasion that your mattress isn’t quite right.
