Mattress Topper vs Mattress Protector: Which Should You Buy?

A mattress topper and a mattress protector may sit on the same bed, but they perform very different jobs. A topper is mainly designed to change how your mattress feels, while a protector helps keep the mattress clean and protected from everyday moisture, spills and stains.

Choosing the wrong product can leave you disappointed. A thin waterproof protector will not make an uncomfortable mattress feel significantly softer, while a thick topper will not provide the same reliable moisture barrier as a waterproof protector.

This guide explains the difference between a mattress topper and a mattress protector, who each product is suitable for and whether you should use both together. You can also explore the complete mattress topper and protector collection at Babus Clothing.

Mattress Topper vs Mattress Protector: The Quick Answer

Choose a mattress topper if you want to add softness, cushioning or an extra layer of comfort to your existing mattress.

Choose a mattress protector if your main priority is protecting your mattress from spills, sweat, stains and everyday moisture.

Choose a zipped mattress encasement if you want fuller protection around the top, sides and underside of the mattress.

For comfort and protection together, place a topper on the mattress and fit a waterproof protector over both.

What Is a Mattress Topper?

A mattress topper is a removable layer placed directly on top of a mattress. Its main purpose is to adjust the feel of the sleeping surface.

Depending on its thickness and filling, a topper can add softness and cushioning to a bed that feels too firm. It can also refresh the feel of a guest bed or older mattress that remains supportive but is no longer as comfortable as it once was.

The 10cm extra-thick mattress topper features a 1000GSM fibre filling and corner straps designed to help keep it in place.

Benefits of a Mattress Topper

A mattress topper can:

• Add a softer, more cushioned sleeping surface
• Improve the feel of a mattress that is too firm
• Refresh a guest bed without replacing the mattress
• Add an extra layer between you and the mattress
• Make a temporary bed feel more comfortable
• Provide a removable layer that can be aired and maintained separately

A topper can be especially useful for rental properties, student accommodation and guest bedrooms where replacing the entire mattress may not be practical.

What a Mattress Topper Cannot Do

A mattress topper cannot repair a mattress with broken springs, deep sagging or damaged internal support. It may make the surface feel more comfortable, but it will not correct serious structural problems.

If your mattress has become uneven or no longer provides suitable support, replacing it may be a better long-term solution.

A standard topper also should not be treated as a waterproof protector unless the product description specifically confirms that it includes a waterproof barrier.

What Is a Mattress Protector?

A mattress protector is a removable cover designed to create a protective layer between your fitted sheet and mattress.

Its main purpose is to help prevent sweat, accidental spills, stains and everyday moisture from reaching the mattress. Because a mattress can be difficult to clean thoroughly, a removable protector makes regular bed care much easier.

The waterproof mattress protector available from Babus Clothing features a soft sleeping surface with a waterproof layer underneath. It is available with terry-top and quilted-top options.

Benefits of a Waterproof Mattress Protector

A waterproof protector can:

• Help protect against accidental spills
• Reduce the risk of permanent mattress stains
• Provide a removable and washable surface
• Help keep the mattress feeling fresher
• Protect a new mattress from everyday wear
• Offer practical protection for family and guest bedrooms
• Sit beneath a normal fitted sheet without changing the bed’s appearance

A protector is particularly useful for children’s rooms, guest rooms, rental properties and homes with pets. It is also a sensible addition when purchasing a new mattress that you want to keep in good condition.

Does a Mattress Protector Make a Bed Softer?

A standard protector usually creates little change in mattress firmness. A quilted design may add a small amount of padding, but it will not provide the same level of cushioning as a thick mattress topper.

If your main concern is comfort, choose a topper. If your main concern is spills and stains, choose a waterproof protector.

Terry or Quilted Mattress Protector: Which Is Better?

Both styles protect the mattress, but the surface feel is different.

Terry-Top Mattress Protector

A terry-top protector has a soft, textured surface similar to towelling. It is a practical option for regular family use and provides a comfortable layer beneath your fitted sheet.

Choose a terry-top protector if you want:

• A simple everyday design
• A soft, absorbent-feeling surface
• Lightweight mattress protection
• Minimal additional padding

Quilted-Top Mattress Protector

A quilted protector includes light padding across the sleeping surface. It can feel slightly more cushioned than a flat or terry-top design.

Choose a quilted protector if you want:

• A smoother, padded surface
• Light additional cushioning
• A more substantial bedding feel
• Protection and gentle comfort in one layer

A quilted protector is still much thinner than a mattress topper. It should not be selected as a replacement for a thick comfort layer.

What Is a Zipped Mattress Encasement?

A standard protector usually covers the top and sides of the mattress. An encasement surrounds the entire mattress, including the underside, and closes with a zip.

The waterproof zipped mattress encasement provides full mattress coverage and includes a breathable surface, waterproof barrier and secure zip closure.

A full encasement can be suitable for:

• Guest bedrooms
• Children’s beds
• Rental and holiday properties
• Long-term mattress storage
• Homes with pets
• Anyone wanting coverage around the whole mattress

An encasement takes slightly longer to fit because the mattress must be lifted and placed inside it. However, it provides more complete coverage than a standard fitted protector.

Should You Buy a Mattress Topper?

A topper may be the right option if:

• Your mattress feels firmer than you prefer
• You want a softer, more cushioned bed
• Your guest mattress needs additional comfort
• You want to refresh the feel of your existing bed
• You need a temporary comfort upgrade
• Your mattress remains supportive but feels less inviting

A topper is also helpful when two people have different comfort preferences. Although it will change the feel of the full bed, choosing the right level of cushioning can make the sleeping surface more comfortable for both.

Should You Buy a Mattress Protector?

A protector may be the better choice if:

• You recently purchased a new mattress
• You want protection from spills and stains
• The bed is used by children or guests
• You have pets that enter the bedroom
• You want a removable layer that is easier to wash
• Your mattress is already comfortable
• You want to improve everyday mattress care

A protector is a relatively simple way to reduce direct contact between the mattress and everyday moisture.

Can You Use a Mattress Topper and Protector Together?

Yes. Using both products gives you the comfort of a topper and the practical protection of a waterproof cover.

The recommended order is:

1. Mattress

2. Mattress topper

3. Waterproof mattress protector

4. Fitted sheet

5. Duvet and other bedding

Placing the protector over both the mattress and topper helps protect the full sleeping surface. However, you must make sure the protector is deep enough to fit around the combined mattress and topper.

A 10cm topper adds noticeable height to the bed. Measure the total depth before purchasing a fitted protector or sheet.

How to Select the Correct Size

UK mattress sizes can vary between manufacturers, so check the actual length, width and depth of your mattress before ordering.

Common UK sizes include:

• Single
• Small double
• Double
• King
• Super king

The size name alone may not be enough. A deep mattress combined with a thick topper may require a deeper protector and fitted sheet.

How to Measure Your Bed

Remove the existing bedding and measure:

• The mattress width from side to side
• The mattress length from head to foot
• The mattress depth from top to bottom
• The topper depth if you plan to use one

Add the mattress and topper depths together when choosing a protector that will cover both.

For a zipped encasement, compare the complete mattress dimensions with the measurements listed on the product page.

Is a 10cm Mattress Topper Too Thick?

A 10cm topper provides a noticeably cushioned sleeping surface. It may be suitable if your mattress feels too firm or you prefer a plush bed.

However, a thicker topper also raises the overall height of your bed. This may affect:

• How easily your fitted sheet stays in place
• Whether your current protector is deep enough
• How easy it is to get in and out of bed
• The appearance of the mattress within the bed frame
• The fit of other bedding

Measure carefully before buying. A thick topper should sit securely on the mattress without extending beyond its edges.

Which Option Is Best for a Guest Bed?

A mattress topper and protector can both be useful in a guest room.

A topper helps create a softer and more inviting sleeping surface, particularly when the guest mattress is firm. A waterproof protector helps keep the bed clean between visitors and creates a removable layer that can be washed.

For holiday lets and frequently used guest rooms, a zipped encasement can provide additional coverage around the mattress.

Using both a topper and protector can help create a comfortable, practical guest bed without replacing a mattress that remains in usable condition.

Which Option Is Best for Children’s Beds?

A waterproof mattress protector is usually the first priority for a child’s bed because accidental spills can happen easily.

Choose a protector that:

• Fits securely around the mattress
• Has a waterproof barrier
• Provides a comfortable sleeping surface
• Can be removed without difficulty
• Is suitable for regular washing

A topper can be added if the mattress requires more cushioning, but it should also be covered by the waterproof protector.

Which Option Is Best for Rental Properties?

Landlords and holiday-property owners may benefit from using a protector or full encasement on every mattress.

A standard waterproof protector is easy to remove between guests, while a zipped encasement provides coverage around the entire mattress. A topper may be added when the mattress needs additional softness but does not need replacing.

Always follow current safety, cleanliness and accommodation requirements relevant to your type of property.

Common Buying Mistakes to Avoid

Expecting a Protector to Add Significant Comfort

A protector is mainly intended for mattress care. Select a topper if you need additional softness.

Expecting a Topper to Waterproof the Mattress

Most toppers do not provide reliable waterproof protection. Use a waterproof protector over the topper.

Ordering by Size Name Alone

Mattress depths can vary considerably. Always check the exact measurements.

Ignoring the Extra Height of a Topper

A thick topper can make standard fitted sheets or protectors too shallow.

Using a Topper on a Damaged Mattress

A topper can adjust surface comfort, but it cannot repair serious sagging or broken internal support.

Choosing a Loose Protector

An incorrectly sized protector may move, crease or become uncomfortable beneath the fitted sheet.

How to Care for Your Topper and Protector

Always check the individual care label because washing instructions can vary by material and construction.

General care tips include:

• Use a fitted sheet over your protector
• Remove bedding regularly to allow the bed to air
• Wash the protector after spills and as part of routine bedding care
• Make sure every layer is completely dry before returning it to the bed
• Avoid excessive heat unless the care label permits it
• Rotate or gently shake a fibre topper to redistribute the filling
• Check corner straps and zips regularly
• Avoid using bleach unless specifically permitted

For a zipped encasement, close the zip before washing to help protect it during the cycle.

Final Verdict: Which Should You Buy?

Buy a mattress topper when comfort is your priority.

Buy a mattress protector when keeping the mattress clean is your priority.

Buy a zipped mattress encasement when you want protection around the whole mattress.

Buy both a topper and waterproof protector when you want to improve comfort while also protecting the mattress and topper from everyday moisture.

The correct choice depends on the condition of your mattress, your preferred sleeping feel and how the bed is used.

Frequently Asked Questions

Is a mattress topper the same as a mattress protector?

No. A topper adds cushioning and changes how the bed feels. A protector creates a barrier between the sleeper and mattress to help guard against spills, stains and moisture.

Do I need a protector if I already have a topper?

A waterproof protector is still useful because most toppers are not waterproof. Place the protector over both the topper and mattress.

Does the topper go above or below the mattress protector?

Place the topper directly on the mattress and fit the protector over both. Add your fitted sheet last.

Can a topper fix an old mattress?

A topper may make a firm mattress feel softer, but it cannot repair broken springs, deep sagging or damaged support.

Is a quilted protector the same as a topper?

No. A quilted protector may provide light padding, but it is much thinner than a mattress topper and is mainly designed for protection.

Is a zipped encasement better than a fitted protector?

It depends on your needs. A fitted protector is easier to remove, while a zipped encasement surrounds the entire mattress for fuller coverage.

What size mattress protector should I buy?

Choose the size that matches your mattress and check the depth. If you use a topper, include its thickness when calculating the total depth.

Can mattress protectors be washed?

Many protectors are machine washable, but you should always follow the product’s specific care label.

Should a new mattress have a protector?

A protector can help keep a new mattress clean by reducing direct exposure to spills, sweat and everyday moisture.

Which is better for a guest bed?

Using both can be helpful. A topper improves comfort, while a protector makes the sleeping surface easier to maintain between visitors.
