A crib mattress cover can help protect the mattress from diaper leaks, spit-up, and everyday spills, but the right choice depends on how it fits, how it fastens, and what materials you prefer.

Our Picks: Best Baby Crib Mattress Cover reviews
Utopia Bedding: Best for Full-Mattress Encasement
The Utopia Bedding protector is a zippered encasement designed to cover the top, bottom, and sides of a crib mattress. It fits a mattress measuring 28 by 52 inches and up to 7 inches deep. That full wraparound design is its main distinction from fitted pads that only cover the sleep surface and edges.
The cover uses smooth knitted polyester and has a waterproof layer intended to block liquids from reaching the mattress. Its zipper closes around the mattress, while the stretchy fabric is designed to help the cover stay in place. The maker also describes it as bed bug and dust mite proof; that feature is separate from the waterproof function.
This is a practical pick if you want enclosed coverage rather than a removable pad over the top. The trade-off is that a zippered cover takes more effort to remove and put back on than a simple fitted protector, especially when the mattress needs a full change. Check the mattress depth before buying, since this model is specified for mattresses up to 7 inches deep.
Pros:
- Encloses the mattress on all sides
- Waterproof barrier helps protect against spills and leaks
- Quiet, smooth knitted fabric
- Machine washable and suitable for low-heat tumble drying
Cons:
- Fits mattresses up to 7 inches deep, so it may not suit thicker models
- Putting on a full encasement takes more work than fitting a pad
Verdict: Choose the Utopia Bedding protector if you want a waterproof zippered cover around the entire mattress and your mattress matches its size limits.
Sealy Baby SafetyCase: Best Zippered Option With a Soft Top
The Sealy Baby SafetyCase is a full zippered encasement for a standard full-size crib mattress. It surrounds the mattress to help keep the cover from shifting beneath the fitted sheet. Its soft micro-weave surface and light quilting give it a different feel from the smooth, non-quilted surface of the Utopia Bedding option.
The waterproof layer is designed to block common nursery messes, including diaper leaks and spit-up. The product description also says the materials are tested to meet quality standards for baby products, but it does not name a specific certification. It is machine washable and dryer friendly, which can be useful when the cover needs a thorough clean.
The full enclosure is useful if you want the mattress covered on every side, but confirm that your mattress is a standard full-size crib mattress before ordering. Compared with a fitted pad, the zipper provides a more enclosed fit but makes removal and replacement a longer task. The product description does not specify a maximum mattress depth, so check the listing for fit details if your mattress is unusually thick.
Pros:
- Full zippered coverage helps keep the protector in place
- Soft micro-weave surface with light quilting
- Waterproof layer helps block everyday liquid messes
- Washer and dryer friendly
Cons:
- Full enclosure takes longer to remove than a fitted pad
- Specific mattress-depth limits are not included in the supplied product details
Verdict: The Sealy Baby SafetyCase is a good match if you want a soft-topped, washable zippered encasement and have a standard-size crib mattress.
Graco Premium: Best Two-Pack for Easier Changes
Graco’s protector is a fitted style rather than a zippered encasement. Its elasticized bottom is designed to provide a snug fit on standard full-size crib and toddler mattresses. The two-pack can be helpful when you want a clean spare ready while the other protector is in the wash.
The waterproof sleep surface uses a PVC-free TPU coating. The product is GREENGUARD Gold Certified, and the description says it is screened for a range of chemicals and volatile organic compounds. It can be washed in cold water on a delicate cycle and tumble dried on low heat or hung to dry. The product also includes a five-year limited warranty, so check its terms for coverage details.
Compared with the zippered choices, this fitted protector should be simpler to take off and replace, but it does not fully enclose the mattress. It is a useful choice for routine spills and laundry convenience, provided the fitted style and standard mattress size meet your needs. Follow the care instructions to help maintain the waterproof surface.
Pros:
- Two protectors provide a spare for quick changes
- Elasticized bottom makes it a fitted, non-zippered style
- PVC-free TPU waterproof coating
- GREENGUARD Gold Certified and machine washable
Cons:
- Does not fully encase the mattress
- Requires delicate-cycle washing and low-heat drying or air drying
Verdict: Pick the Graco two-pack if you prefer a simple fitted cover and value having a spare available for laundry days.
Naturepedic: Best Organic Cotton Mattress Pad
The Naturepedic protector is a fitted mattress pad with a waterproof barrier. Its top and bottom layers are made from GOTS-certified organic cotton, with a thin membrane between them to block liquids. This construction makes it a distinct option for shoppers who want an organic cotton surface rather than a polyester cover.
The maker describes the pad as breathable, absorbent, and noiseless, and says it contains no vinyl, PVC, or phthalates. It is machine washable. The specified fit is for a mattress measuring about 27¼ by 51⅝ inches and 6 inches deep, so check your mattress dimensions carefully rather than assuming every “standard” mattress will fit the same way.
Unlike the Utopia Bedding and Sealy choices, this is not a zippered encasement. It covers the sleep surface as a fitted pad, which is simpler to remove but does not surround the mattress. It is also not the same as an absorbent pad without a waterproof membrane: the waterproof barrier is a key part of this design.
Pros:
- GOTS-certified organic cotton top and bottom layers
- Thin waterproof membrane helps block liquids
- Made without vinyl, PVC, or phthalates, according to the product description
- Machine washable
Cons:
- Fitted pad does not enclose the mattress
- Specified mattress dimensions may not match every crib mattress
Verdict: The Naturepedic pad is a strong option if organic cotton and a fitted waterproof design matter more to you than full-mattress enclosure.
Avocado: Best for Certified Organic Materials
The Avocado protector is a fitted pad made with two layers of GOTS-certified organic cotton around a thin waterproof membrane derived from cornstarch. The product description says the finished product is certified organic and also lists OEKO-TEX Class I, GREENGUARD Gold, Formaldehyde-Free, and MADE SAFE certifications.
This is a removable protective pad, not a sealed encasement. Its fitted skirt is sized for a 28-by-52-inch mattress that is 8 inches deep. The pad is made oversized because the organic cotton is expected to shrink to fit after the first few washes. Wash it before use and follow the care directions: tumble dry on low and do not use bleach.
Compared with Naturepedic, Avocado specifies a deeper mattress fit and describes a plant-based barrier, while Naturepedic gives a different mattress size and depth. Both are fitted protectors, so neither offers the all-side enclosure of the zippered options. Avocado’s material and certification details may appeal to shoppers who place extra importance on those specifications, but its care and shrink-to-fit instructions are important to plan for.
Pros:
- Two layers of GOTS-certified organic cotton
- Waterproof membrane derived from cornstarch
- Product description lists several material and emissions certifications
- Fits mattresses up to 8 inches deep, according to the stated dimensions
Cons:
- Fitted pad does not fully enclose the mattress
- Oversized fit is intended to shrink after washing, so care instructions matter
Verdict: Choose Avocado if you want an organic cotton fitted protector with a plant-based waterproof barrier and are comfortable following its wash-before-use instructions.
How to Choose the Best Baby Crib Mattress Cover
Check the Mattress Dimensions and Depth
Start with the mattress label or manufacturer’s product details. A protector that is too small may not fit securely, while one that is too large can bunch. Compare both the length and width, then check the maximum mattress depth. The options here have different stated limits: Utopia Bedding specifies up to 7 inches, Naturepedic lists a 6-inch-deep mattress, and Avocado lists an 8-inch-deep mattress. For a product with unclear depth details, confirm the fit before ordering.
Choose Between a Fitted Pad and a Zippered Encasement
A fitted protector covers the mattress surface and is generally simpler to remove for washing. The Graco, Naturepedic, and Avocado options use this style. A zippered encasement wraps around the mattress, as with the Utopia Bedding and Sealy Baby options. That design provides coverage on more sides but takes more effort to remove and put back on. Decide which setup best suits your cleaning routine and coverage preference.
Compare Waterproof Materials and Construction
All five products are described as waterproof, but their materials differ. Graco uses a PVC-free TPU coating; Naturepedic pairs organic cotton layers with a thin membrane; Avocado describes a plant-based membrane; and Utopia Bedding and Sealy Baby use waterproof layers in their encasements. If you have material preferences, read the product details closely and distinguish a stated feature from a certification or test claim.
Consider the Surface Feel and Noise
The cover sits beneath the fitted crib sheet, so its texture and construction can still matter. Utopia Bedding describes a smooth, non-crinkling knitted fabric, while Sealy Baby uses a soft micro-weave surface with light quilting. Naturepedic and Avocado emphasize cotton layers and a thin barrier. These descriptions can help narrow your choice, but they do not replace checking that the cover fits smoothly on your specific mattress.
Think About Laundry and Spares
Check washing and drying instructions before you buy, especially if you expect to wash the protector often. Graco calls for cold water on a delicate cycle and low-heat drying or hanging to dry. Avocado says to wash before use, tumble dry low, and avoid bleach. Utopia Bedding specifies machine washing and low-heat tumble drying. A two-pack, such as Graco’s, gives you a spare while the other cover is being cleaned.
Keep the Crib Sleep Setup Simple
Choose a protector that fits the mattress properly and lays flat beneath the fitted sheet. Avoid adding bulky layers or using a cover that bunches. Follow the crib, mattress, and protector instructions for setup and care so the cover remains properly fitted.
Frequently Asked Questions
What is the difference between a crib mattress cover and a mattress pad?
The terms can overlap, but the construction matters more than the name. A fitted pad covers the sleep surface and edges, while a zippered encasement wraps around the mattress. Check the product description to see which style you are buying.
Do all crib mattress protectors fit every standard crib mattress?
No. Mattress dimensions and depth can vary, and the products in this guide list different fit limits. Measure your mattress and compare its length, width, and depth with the protector’s specifications before ordering.
Is a zippered crib mattress protector better than a fitted one?
Neither style is best for every household. An encasement covers more of the mattress but takes longer to remove and replace. A fitted protector is easier to handle but does not surround the mattress. Choose based on your preferred coverage and laundry routine.
Can I use a waterproof protector beneath a fitted crib sheet?
These products are designed as mattress protectors, but check the instructions for the specific cover and mattress. The protector should fit smoothly and securely beneath the fitted sheet, without loose or bunched fabric.
How should I wash a crib mattress cover?
Follow the care label for your specific product. Instructions vary: some allow machine washing and low-heat drying, while Graco specifies a delicate wash cycle and Avocado calls for washing before use and avoiding bleach.
Which option is best if I want a spare protector?
Graco’s product is sold as a two-pack, so it provides a spare in the same purchase. Having an extra can make it easier to replace a soiled cover while the other one is in the wash.
Which crib mattress cover is best for organic materials?
Naturepedic and Avocado both describe organic cotton layers. Avocado also lists certifications for the finished product and a plant-based waterproof barrier. Compare each product’s stated mattress fit and care instructions before choosing.
Final Recommendation
For full-mattress coverage, consider the Utopia Bedding or Sealy Baby zippered encasement, paying close attention to mattress fit. For a fitted style with a spare included, Graco’s two-pack is the practical choice. If organic cotton is a priority, compare Naturepedic’s specified mattress dimensions with Avocado’s deeper fit and wash-before-use instructions. The best pick is the one that fits your mattress snugly and matches the materials, coverage, and care routine you want.
