A double bed mattress cover is a protective layer designed to fit over a double mattress, helping protect the mattress from dust, moisture, spills, stains and everyday wear. In Australia, a standard double mattress is generally 138 × 188 cm, although mattress depth can vary considerably between models.
A mattress cover may refer to a fitted mattress protector, waterproof protector, quilted cover or fully encased mattress cover. The best option depends on whether your priority is comfort, waterproof protection, allergy protection, durability or easy washing.
A mattress is a significant part of your bedroom, so protecting it can help maintain its condition for longer.
Here’s why a double bed mattress cover is useful:
The most important measurement is the mattress itself.
A standard Australian double mattress is approximately:
138 cm wide × 188 cm long
However, you should also measure the mattress depth.
For example, some fitted double mattress protectors are designed for mattresses approximately 20–40 cm deep, while extra-deep versions can accommodate greater depths.
Always check:
A waterproof mattress cover includes a protective barrier designed to prevent liquid from reaching the mattress.
It can be particularly useful for:
Some Australian mattress protectors use waterproof yet breathable membranes rather than noisy plastic-style layers.
A quilted cover adds a layer of padding between the sleeper and mattress.
It can provide a softer feel while offering everyday mattress protection. Some quilted protectors use cotton surfaces and polyester filling.
A fitted mattress protector is shaped like a fitted sheet and wraps around the mattress.
Elasticated edges help keep the protector securely positioned during sleep.
A fully encased mattress protector surrounds the mattress more comprehensively than a standard fitted protector.
Some designs provide waterproof protection across the full mattress enclosure and are available in standard and deeper double sizes.
Some mattress protectors are designed with treatments or materials intended to help reduce exposure to common allergens such as dust mites.
If allergies are a consideration, check the manufacturer's specific claims, certifications and care instructions.
A waterproof double bed mattress cover can provide an important layer of protection against moisture.
Look for:
Some waterproof Australian mattress protectors combine a soft sleeping surface with a waterproof membrane and fitted skirt.
A mattress cover can be particularly practical in a child's bedroom.
Children's mattresses can be exposed to:
A washable waterproof protector can make maintaining the mattress considerably easier.
A mattress cover is also useful for guest rooms.
A washable protector helps keep the mattress fresh between guests while providing an additional layer of protection.
For a guest bedroom, consider a cover that is:
Australian bedrooms can become warm during summer, so the material of the mattress cover matters.
Look for breathable fabrics such as cotton or other moisture-managing materials.
A breathable waterproof membrane can also be useful where moisture protection is required without creating an excessively warm sleeping surface.
During cooler months, a quilted mattress protector can add a subtle layer of softness and warmth.
Pair it with:
The mattress cover should still allow the mattress to retain its intended comfort and support.
Measure the width, length and depth of your mattress.
Do not assume that every double mattress has the same depth.
If spills and moisture are a concern, choose a waterproof design.
For general everyday protection, a standard fitted protector may be sufficient.
Cotton and breathable technical fabrics can be useful if you tend to sleep warm.
A cover that is too shallow can pull away from the corners, while an excessively loose cover may move during the night.
A removable, machine-washable protector is convenient for regular maintenance.
The terms mattress cover and mattress protector are often used interchangeably.
However, "mattress cover" can describe a broad range of products, while "mattress protector" usually implies a product specifically designed to protect the mattress from spills, stains, allergens or general wear.
Always check the actual features rather than relying only on the product name.
These products serve different purposes.
A mattress protector is primarily designed to protect the mattress.
A mattress topper is primarily designed to change or enhance the feel of the mattress by adding cushioning or support.
A topper is generally thicker, while a mattress cover is much thinner and designed to sit directly over the mattress.
A well-fitted cover should stay relatively secure throughout the night.
Look for:
Some Australian fitted protectors use skirts that stretch to accommodate mattresses of different depths.
Always follow the manufacturer's care label.
Where machine washing is permitted:
Many Australian mattress protectors are machine washable for easier hygiene and maintenance.
The ideal frequency depends on usage, household conditions and the manufacturer's care instructions.
Wash more frequently if the cover is exposed to:
Using a washable cover makes regular maintenance much easier.
A mattress cover is usually hidden beneath the fitted sheet, so it does not need to influence your decorative styling.
For a beautifully finished double bed, layer:
A well-made bed combines practical protection underneath with beautiful textiles on top.
For contemporary bedrooms, focus on a clean and practical bedding system.
Pair your mattress cover with:
The protective layer remains discreet while the decorative bedding creates the visual character.
Coastal interiors suit light, breathable and natural-looking bedding.
Consider:
Layer the bed with a relaxed throw and simple cushions for an effortless coastal feel.
A Hamptons-inspired bedroom can combine a practical mattress protector with elegant layered bedding.
Consider:
The mattress cover remains hidden while helping protect the underlying mattress.
A double bed mattress cover is a practical foundation for creating a clean, comfortable and beautifully maintained bedroom.
Once the mattress is protected, you can build the decorative layers around it with quality bedding, cushions, throws, bedheads, bedside furniture, lamps and rugs.

For a standard Australian double mattress, look for a cover designed for approximately 138 × 188 cm. You should also check the mattress depth before purchasing.
Some are waterproof and others are not. If protection from spills and moisture is important, specifically choose a waterproof mattress protector.
A quilted or padded protector can add a small amount of softness. However, a mattress topper will generally have a much greater effect on the overall feel of the mattress.
The required depth depends on your mattress. Standard double protectors may accommodate around 20–40 cm, while extra-deep designs can accommodate greater depths.
Yes, but check the total height of the mattress plus topper. You may need a deeper fitted protector to accommodate both.
Many modern waterproof protectors use breathable membrane technology designed to allow moisture vapour to pass while blocking liquid. Always check the specifications of the individual product.
Many are machine washable, but washing instructions vary. Always follow the manufacturer's care label.
A double bed mattress cover is a simple but valuable addition to a well-designed bedroom. It helps protect your mattress from everyday wear, moisture and spills while creating a clean foundation for beautiful bedding.
For Australian double beds, start with the key measurement of 138 × 188 cm, then check the mattress depth and choose between standard, quilted, waterproof, allergy-focused or fully encased protection according to your needs.
