Our Picks: Best Mattress Cover For Sofa Bed reviews
Moonsea Waterproof Sofa Bed Mattress Pad: Best Quilted Fitted Pad
The Moonsea is a fitted mattress pad made for a queen sofa-bed mattress measuring 60 by 72 inches. Its microfiber top and quilted, down-alternative filling create a padded layer, while a TPU barrier is designed to help keep liquids from reaching the mattress.
The all-around elastic skirt is made to fit mattresses up to 8 inches deep. That can make this a practical choice if you want a pad that pulls on like a fitted sheet rather than a zippered cover. The quilted design also helps keep the filling in place, according to the product description.
Compared with the encasements below, the Moonsea adds a more cushioned layer but does not enclose the mattress on every side. It’s a good match for routine spills and moisture protection when you prefer a padded sleeping surface. Measure your sofa-bed mattress first, especially if it is not the listed 60-by-72-inch size.
Pros:
- Quilted, padded surface with microfiber top
- TPU layer is designed to help block liquids
- Fitted style with elastic around the skirt
- Machine washable and suitable for low-heat drying
Cons:
- Does not fully encase the mattress like a zippered protector
- Designed for a specific 60-by-72-inch mattress size
Verdict: Choose the Moonsea if you want a quilted fitted pad with a waterproof layer and your mattress matches its dimensions.
Utopia Bedding Zippered Protector: Best Slim-Fit Encasement
This Utopia Bedding protector is a zippered encasement for a 60-by-72-inch queen sofa-bed mattress up to 5 inches deep. Its stretch-knit polyester fabric is described as soft and quiet, and the wraparound zipper closes the cover around the mattress for coverage on all sides.
The waterproof layer is intended to help protect against spills, sweat, and everyday accidents. Because this model is designed for mattresses no deeper than 5 inches, it may suit slimmer sleeper-sofa mattresses better than options with deeper pockets. Check the mattress depth carefully before ordering; a cover that is too shallow may be difficult to close or fit properly.
Unlike a fitted pad, this cover surrounds the mattress rather than adding a quilted layer on top. That makes it a practical pick when full coverage matters more than extra padding. The product is machine washable and can be tumble dried on low.
Pros:
- Zippered design covers all sides of the mattress
- Waterproof barrier is intended to block everyday liquids
- Stretchy, smooth fabric is described as quiet and comfortable
- Machine washable and suitable for low-heat tumble drying
Cons:
- Maximum listed mattress depth is 5 inches
- Does not provide the quilted padding of a mattress pad
Verdict: The Utopia Bedding cover is a strong option if you want a zippered, all-side protector for a slim 60-by-72-inch sofa-bed mattress.
Allersoft Mattress Cover: Best for Full Mattress Enclosure
The Allersoft is a zip-closed cover designed to enclose a sofa-bed mattress on all six sides. It measures 60 by 72 inches and has stretch sides intended for mattresses 4 to 7 inches deep. This is not a fitted pad: the mattress goes inside the cover, which closes with a locking zipper.
The fully enclosed design is meant to shield the mattress from dust, pet dander, pollen, and liquids. That broad coverage can be useful if you want to protect the sides and bottom as well as the sleeping surface. The key trade-off is fit: the product description warns that some mattresses sold as queen size are 80 inches long, which will not fit this shorter cover.
Compared with fitted options, the Allersoft offers a more complete barrier but takes more effort to put on and remove. It also does not add the quilted cushioning found on the Moonsea pad. The manufacturer states that the product includes a lifetime warranty on workmanship.
Pros:
- Encloses the mattress on all six sides
- Locking zipper is designed to secure the closure
- Stretch sides fit listed depths from 4 to 7 inches
- Manufacturer states it includes a lifetime workmanship warranty
Cons:
- Requires removing the mattress to install the encasement
- Will not fit an 80-inch-long mattress
Verdict: Pick the Allersoft if full enclosure is your priority and you have confirmed that your mattress measures 60 by 72 inches and 4 to 7 inches deep.
Four Seasons Essentials Encasement: Best for Waterproof All-Side Coverage
Four Seasons Essentials offers a six-sided zippered encasement sized for a 60-by-72-inch sofa-bed mattress. It is designed for mattresses 5 to 8 inches deep, giving it a wider depth range than the Utopia Bedding protector. A polyurethane inner lining is described as a waterproof barrier against liquids and moisture.
The cover uses a zipper that wraps around three sides, with a Velcro seal over the zipper. Its stretch fabric is described as soft, breathable, and noiseless. These details make it worth considering if you want full coverage without a stiff or crinkly feel under your bedding.
As with other encasements, putting it on takes more work than slipping on a fitted pad. The broad depth range is useful, but the listed length and width still need to match your mattress. It is machine washable, so you can clean it as needed.
Pros:
- Six-sided encasement with a zipper and Velcro seal
- Waterproof polyurethane lining
- Fits listed mattress depths from 5 to 8 inches
- Stretch fabric is described as soft and noiseless
Cons:
- More involved to install than a fitted pad
- Does not add a quilted layer for extra cushioning
Verdict: Choose this cover if you need a waterproof, zippered encasement and your sofa-bed mattress falls within its 5-to-8-inch depth range.
Luv4babe Terry-Top Protector: Best Simple Fitted Cover
The Luv4babe protector is a fitted pad for a 60-by-72-inch sofa-bed mattress up to 8 inches deep. Its smooth terry top is intended to feel softer than a bare mattress, while a built-in liquid-resistant layer helps guard against spills and everyday moisture.
This design stretches over the mattress like a fitted sheet and is meant to stay in place. It is a straightforward choice for guest rooms or sleeper sofas when you want a washable cover without a zipper enclosure. The product description says it is machine washable and built with sturdy stitching for regular washing.
One distinction to keep in mind is that the product is described as liquid-resistant, not as a fully waterproof encasement. It covers the top and sides in a fitted style, so it does not provide the same all-around enclosure as the zippered options. Compared with the quilted Moonsea, it also has a smooth terry surface rather than a quilted, filled top.
Pros:
- Smooth terry top provides a soft sleeping surface
- Fitted style is designed for mattresses up to 8 inches deep
- Liquid-resistant layer helps guard against everyday moisture
- Machine washable for easier care
Cons:
- Described as liquid-resistant rather than fully waterproof
- Does not enclose the mattress with a zipper
Verdict: The Luv4babe is a practical fitted option if you want a terry-top surface and basic moisture protection rather than a full encasement.
How to Choose a Mattress Cover for a Sofa Bed
Measure the Mattress While It Is Open
Do not rely on the word “queen” alone. Sofa-bed mattresses can be shorter than standard queen mattresses, and the options here are designed for a 60-by-72-inch mattress. Measure the mattress width and length when it is fully open, then compare those numbers with the product listing. A cover that is too long or wide can bunch up, while one that is too small may not close or stay in place.
Check Mattress Depth
Depth is just as important as width and length. The fitted Moonsea and Luv4babe options fit mattresses up to 8 inches deep. The Utopia Bedding protector is made for mattresses up to 5 inches deep, the Allersoft fits 4 to 7 inches, and the Four Seasons Essentials option fits 5 to 8 inches. Measure the thickest part of your mattress, including any built-in padding.
Choose Between a Fitted Pad and an Encasement
A fitted pad pulls over the top and sides of the mattress, much like a fitted sheet. It is usually simpler to put on and can offer a padded or terry surface. A zippered encasement surrounds the mattress, including its bottom, but takes more effort to install. Choose a pad for easier everyday use or an encasement when all-side coverage is important to you.
Match the Protection to Your Needs
Look closely at how each product describes its barrier. The Moonsea and Four Seasons Essentials options are described as waterproof. The Utopia Bedding cover also has a waterproof layer. The Luv4babe product is described as liquid-resistant, which is not the same claim as fully waterproof. The Allersoft is designed to seal the mattress from dust, pet dander, pollen, and liquids. If spill protection is your main concern, compare these details rather than assuming all covers offer the same level of protection.
Consider Comfort and Added Padding
A mattress cover can change how the sofa bed feels. The Moonsea has a quilted top with down-alternative filling, while the Luv4babe has a smooth terry surface. The encasements focus more on enclosing and protecting the mattress than adding cushioning. If the mattress already feels thin or firm, a padded cover may be more appealing, but it will not replace a mattress topper.
Review Care Instructions
Easy cleaning matters when the sofa bed is used by guests, children, or pets. The listed options are machine washable, but care details differ: the Moonsea should be dried on low heat, and the Utopia Bedding cover is also intended for low-heat tumble drying. Check the care instructions for your chosen cover before washing, and make sure it is fully dry before putting it back on the mattress.
Frequently Asked Questions
Will a standard queen mattress cover fit a sofa bed?
Not always. Some sofa-bed mattresses are shorter than standard queen mattresses. Check the actual width, length, and depth of your open mattress against the cover’s listed measurements before buying.
What size is a queen sofa-bed mattress cover in this guide?
All five options listed here are designed for a 60-by-72-inch mattress. Their depth limits vary, so confirm all three measurements rather than relying on the size label alone.
Is a fitted pad or a zippered encasement better?
It depends on what you need. A fitted pad is easier to put on and may add a softer or quilted surface. A zippered encasement provides coverage around the mattress, including the sides and bottom, but usually takes longer to install.
Are all of these sofa-bed covers waterproof?
No. The product descriptions identify the Moonsea, Utopia Bedding, and Four Seasons Essentials options as waterproof. Luv4babe describes its cover as liquid-resistant. Allersoft describes a sealed, six-sided cover intended to protect against liquids and other contaminants.
Can I leave the cover on when I fold the sofa bed?
The supplied product details do not confirm that each cover is suitable for folding inside a sofa mechanism. Check the sofa-bed instructions and make sure the covered mattress folds without bunching or interfering with the frame.
How do I wash a sofa-bed mattress cover?
Follow the care label for the specific cover. The products in this guide are described as machine washable; the Moonsea and Utopia Bedding listings specify low-heat drying. Avoid assuming that every cover can be washed or dried in the same way.
Final Recommendation
For a quilted surface with a waterproof layer, the Moonsea is the most straightforward fitted-pad choice, provided your mattress is 60 by 72 inches and no more than 8 inches deep. If you prefer a zippered cover, choose between the Utopia Bedding, Allersoft, and Four Seasons Essentials options based on mattress depth and the type of all-side protection you want. For a simple terry-top pad with a liquid-resistant barrier, consider the Luv4babe. In every case, measure your sofa-bed mattress first—fit is the most important step in choosing a cover that works well.
