Waterproof bed sheets can help protect a toddler’s mattress from spills, diaper leaks, and bed-wetting while making cleanup easier. The right fit matters: these picks are designed mainly for standard 52-by-28-inch crib mattresses, and their stated mattress-height limits vary. Check your mattress size and thickness before choosing, especially if your toddler has moved to a larger bed.

Our Picks: Best Waterproof Bed Sheets For Toddlers reviews
1. KeaBabies Organic Cotton Waterproof Crib Sheets: Best Cotton Set
This two-pack pairs a 100% organic cotton sleeping surface with a built-in waterproof layer. Each fitted sheet measures 52 by 28 inches and is designed for a standard crib mattress between 3 and 8 inches deep. The cotton gives this set a different feel from the microfiber options in this guide.
Stretchy SnugFit fabric is intended to make the sheets easier to put on and take off. The built-in protection also means you do not need to add a separate mattress cover, according to the product description. Machine washing and dryer use are listed as care options, which can be useful when one sheet is in the wash.
The main trade-off is that the fit is limited to the stated crib-mattress dimensions. A toddler bed with a larger mattress will need a different size. The description also does not specify how the sheet feels or sounds during movement, so families who are sensitive to fabric noise may want to check product details before buying.
Pros:
- Two fitted sheets are included.
- 100% organic cotton is used for the sheet fabric.
- Built-in waterproof layer helps protect the mattress.
- Designed for mattresses 3 to 8 inches deep.
Cons:
- Fits standard crib dimensions, not every toddler-bed size.
- The product information does not state a specific waterproof-layer material.
Verdict: Choose this set if you want two waterproof fitted sheets with an organic cotton surface and your mattress matches the listed size.
2. KeaBabies Isla Waterproof Crib Sheets: Best Cool-to-the-Touch Feel
The Isla set uses viscose derived from bamboo and has a built-in waterproof lining. The fabric is described as soft and cool to the touch, with temperature-regulating properties. Like the cotton set above, it comes as a two-pack and fits standard 52-by-28-inch crib mattresses from 3 to 8 inches deep.
Stretchy fabric and SnugFit bands are designed to make the sheets easier to fit and help them stay in place. The waterproof lining is intended to protect the mattress without an extra cover. The sheets are listed as machine washable and dryer-friendly, and the neutral color option may suit a range of nursery styles.
This is still a crib-size product, so the “toddler bed” wording should not be taken to mean it fits all toddler mattresses. Check your bed’s mattress measurements. Also, bamboo-derived viscose is not the same material as cotton, so choose based on the fabric feel and care details that work for your household.
Pros:
- Two sheets with a built-in waterproof lining.
- Viscose derived from bamboo is described as soft and cool to the touch.
- Stretchy fit and SnugFit bands are designed to ease changing.
- Fits standard mattresses 3 to 8 inches deep.
Cons:
- Not sized for larger toddler-bed mattresses.
- May not be the right fabric choice if you prefer cotton.
Verdict: This is a practical option if you want two waterproof crib sheets with a bamboo-derived viscose surface and your mattress falls within the stated size range.
3. Magik & Kover Waterproof Crib Sheets: Best for Crib-to-Toddler-Bed Use
These fitted sheets measure 52 by 28 inches and have a deep pocket skirt that stretches to fit mattresses up to 8 inches deep. Their listed fit includes most standard crib and toddler-bed mattresses of those dimensions, so they may work as a child moves between compatible sleep setups.
The sheets use a TPU waterproof membrane, which the product description says protects against liquids such as spills, perspiration, and bed-wetting. An elastic strip around the bottom is intended to hold the sheet in place. Two sheets are included, and the product information describes the fabric as soft and breathable without naming its exact fiber content.
Compared with the cotton and bamboo-derived options, this set provides a specified waterproof-layer material but less detail about the sheet’s fabric composition. The fit is not universal: measure the mattress, including its depth, rather than relying only on the words “crib” or “toddler bed.”
Pros:
- Two fitted sheets are included.
- TPU membrane is specified as the waterproof barrier.
- Designed for standard 52-by-28-inch mattresses up to 8 inches deep.
- Elastic edging is intended to keep the sheet fitted.
Cons:
- The exact sheet-fabric fiber content is not stated in the product details.
- Will not fit a toddler mattress outside the listed dimensions.
Verdict: Consider this set if you need waterproof protection for a standard-size crib or toddler-bed mattress and want the barrier material clearly identified.
4. Biloban Quilted Crib Mattress Protector: Best Padded Option
Unlike a thin fitted sheet, this two-pack is a quilted mattress protector with a four-layer design. It measures 28 by 52 inches and is made to fit most mattresses up to 6 inches deep. The product description highlights a soft, absorbent surface and waterproof protection, making it a different choice from the fitted sheet sets in this roundup.
The added padding may appeal to families looking for a more cushioned protector, and the listing describes the pad as noiseless. It is machine washable and dryer-safe. Having two protectors can also make it easier to put a clean one on while the other is being washed.
There is a fit limitation to keep in mind: its stated maximum mattress depth is 6 inches, less than the 8-inch limit listed for several other picks. It is also a protector pad rather than a basic fitted sheet, so check how it sits on your mattress and whether you want a padded layer under your child’s bedding.
Pros:
- Four-layer quilted construction adds padding.
- Waterproof and described as absorbent and noiseless.
- Two protectors are included.
- Machine washing and drying are listed as care options.
Cons:
- Fits mattresses up to 6 inches deep, so it may not suit thicker mattresses.
- It is a quilted protector, not a simple fitted sheet.
Verdict: Pick this option if you prefer a padded, absorbent mattress protector and your mattress is no more than 6 inches deep.
5. Biloban Waterproof Microfiber Crib Sheets: Best for Simple Care
This two-pack combines a microfiber jersey surface with a waterproof backing. Each fitted sheet measures 52 by 28 inches and is designed for a mattress up to 8 inches deep. The elastic around the sheet is intended to help it fit securely, while the soft, smooth fabric is described as breathable.
The care instructions are specific: machine wash in cold water on a gentle cycle and tumble dry on low. The listing says the sheets dry quickly, which may be helpful when you need to rotate between the two. Compared with the quilted Biloban protector, this option is a fitted sheet rather than a padded mattress layer.
The product description does not name the waterproof-backing material, so shoppers who want to compare specific barrier materials may prefer the Magik & Kover option. As with the other products here, this is a standard crib-size sheet—not a universal fit for every toddler bed.
Pros:
- Two fitted sheets are included.
- Microfiber jersey surface with waterproof backing.
- Fits standard 52-by-28-inch mattresses up to 8 inches deep.
- Care instructions include cold, gentle washing and low-heat drying.
Cons:
- The waterproof-backing material is not specified.
- Does not fit larger toddler-bed mattresses by default.
Verdict: This set suits families who want two easy-care microfiber fitted sheets for a standard crib-size mattress.
How to Choose Waterproof Bed Sheets for Toddlers
Measure the Mattress Before You Buy
Start with the mattress dimensions, not just the bed’s label. Most products in this guide are made for a standard 52-by-28-inch crib mattress, but their depth limits differ. Several fit mattresses up to 8 inches deep, while the quilted Biloban protector is listed for mattresses up to 6 inches deep. Measure both the length and width as well as the height, and compare all three with the product details.
Choose Between a Fitted Sheet and a Padded Protector
A waterproof fitted sheet combines a sleep surface and a protective layer in one item. A quilted protector adds padding and may have a thicker feel. Think about which design you want on the mattress and whether you plan to use another sheet on top. Follow the product’s fit instructions so the bedding sits securely on the mattress.
Compare the Surface Fabric
These options include organic cotton, viscose derived from bamboo, microfiber jersey, and products whose exact sheet-fabric fibers are not identified. The listed materials can help narrow your choice if you have a preferred feel or fabric. Do not assume that all waterproof sheets feel alike: the surface fabric and the construction underneath it can differ.
Check What the Waterproof Layer Is Made Of
Some descriptions identify the barrier material, such as the TPU membrane in the Magik & Kover sheets, while others simply describe a waterproof layer or backing. If knowing the barrier material matters to you, look for it in the product details rather than assuming it is the same across brands. The listed waterproof design can help protect a mattress, but it does not make an incorrect fit suitable.
Plan for Laundry and Backup Bedding
A two-pack gives you a spare sheet or protector while the other is being washed. Check the care directions for the specific product: some list machine washing and dryer use, while the Biloban microfiber sheets specify a cold, gentle wash and low-heat drying. Following the care instructions can help you maintain the fabric and waterproof construction.
Consider How Your Toddler Bed Is Sized
“Toddler bed” can refer to different mattress sizes. A fitted sheet made for a standard crib mattress may fit a toddler bed only when its mattress has matching dimensions and a compatible depth. If your child has moved to a larger mattress, look for waterproof bedding made for that exact bed size instead.
Frequently Asked Questions
Will crib sheets fit a toddler bed?
They can fit if the toddler bed uses a standard 52-by-28-inch mattress and its depth falls within the sheet’s stated range. Measure your mattress before ordering because toddler-bed sizes can vary.
Do waterproof sheets replace a mattress protector?
Several products in this guide have a built-in waterproof layer and are described as protecting the mattress without an extra cover. The Biloban quilted option is itself a mattress protector. Check each product’s construction and instructions to decide whether an additional layer is appropriate.
Which option has the clearest stated waterproof-barrier material?
The Magik & Kover sheets specify a TPU waterproof membrane. Other products describe a waterproof layer, lining, or backing without naming its material in the supplied product details.
Are all of these sheets made from cotton?
No. The KeaBabies cotton set is made with 100% organic cotton, while the Isla set uses viscose derived from bamboo and the Biloban fitted sheets use microfiber jersey. The Magik & Kover description does not identify its exact fabric fiber content.
Which product is designed for a deeper mattress?
The KeaBabies cotton set, KeaBabies Isla set, Magik & Kover sheets, and Biloban microfiber sheets list a fit up to 8 inches deep. The Biloban quilted protector is listed for mattresses up to 6 inches deep.
Can I put these sheets in the dryer?
Several product descriptions list dryer use. The Biloban microfiber sheets specify tumble drying on low, while the other listings describe the products as dryer-friendly or washable and dryable. Follow the care label and product instructions for the item you choose.
Final Recommendation
For a cotton surface and two fitted sheets, the KeaBabies organic cotton set is a strong starting point if your mattress matches its measurements. Choose the KeaBabies Isla set for viscose derived from bamboo, the Magik & Kover sheets if you want a specified TPU barrier, or the Biloban quilted protector if you prefer a padded layer and have a mattress no deeper than 6 inches. The Biloban microfiber set is another straightforward option for a standard crib-size mattress. In every case, confirm the mattress dimensions and depth before you buy.
