Our Picks: Best Mattress Protector For Foam Mattress reviews
PlushDeluxe Bamboo: Quiet Waterproof Coverage for Foam Beds
The PlushDeluxe protector is a waterproof fitted cover designed to protect a mattress from spills, sweat, and other moisture. Its surface is made from bamboo-derived viscose, and the description says it is made to feel soft and stay quiet rather than crinkle as you move.
It is listed for memory foam, latex, and spring mattresses, with a pocket that fits mattresses up to 18 inches deep. That makes it a straightforward option if you want full waterproof protection and a cover that accommodates a range of bed types. The king-size version measures 76 by 80 inches.
The main trade-off is that this is a protective layer, not a padded mattress topper. If you want extra cushioning, this cover is not described as adding it. Also check your mattress depth and bed size before ordering, since the listed dimensions and fit limit are specific.
Pros:
- Waterproof barrier for spills and bodily fluids
- Designed for foam, latex, and spring mattresses
- Described as breathable and noiseless
- Fits mattresses up to 18 inches deep
Cons:
- Does not claim to add cushioning to the mattress
- The listed king size may not suit other mattress sizes
Verdict: Choose the PlushDeluxe if you want a quiet, waterproof protector with a soft bamboo-derived surface and a fit intended for foam beds.
Kool-Flow Organic Cotton: A Water-Resistant, Breathable Option
The Kool-Flow protector pairs an organic cotton surface with Greenshield water-resistant treatment. Its description specifically presents it as a protector for memory foam and other mattress types that aims to preserve the feel of the bed while adding a breathable layer.
Unlike the other waterproof choices here, this one is described as water-resistant, not fully waterproof. That distinction matters if you need a barrier for larger spills or frequent accidents: water resistance may suit everyday moisture protection, but it is not the strongest match when a fully waterproof cover is a priority. The product description says the finish is durable and washable.
Its cotton construction may appeal if you prefer a natural-fiber surface over microfiber or Tencel. The available product details do not state a mattress depth limit, so check the listing for sizing and pocket-fit information before buying.
Pros:
- Organic cotton surface
- Water-resistant Greenshield finish
- Designed for memory foam and several other mattress types
- Washable construction
Cons:
- Water-resistant rather than described as fully waterproof
- Mattress depth limit is not provided in the supplied details
Verdict: The Kool-Flow is worth considering if you want a cotton protector that helps resist moisture while keeping the foam mattress’s feel in focus, but choose a waterproof model for stronger liquid protection.
SheRest: Deep-Pocket Waterproof Protection for Busy Beds
SheRest combines a brushed microfiber surface with a TPU waterproof backing. The cover is designed to block liquids and resist stains, making it a practical pick for households dealing with spills, pets, or bed-wetting. Its description also emphasizes a quiet surface and a breathable, moisture-wicking design.
The fitted skirt is listed for mattresses from 6 to 18 inches deep, including memory foam, hybrid, and pillow-top beds. That broad depth range is useful if your foam mattress is taller than average, though you should still measure your mattress to confirm the fit.
This is a queen-size product, so it is not the right size for every bed. The description recommends cold-water machine washing and tumble drying on low. Follow those care instructions to help maintain the cover and its waterproof layer.
Pros:
- Waterproof TPU backing for liquid protection
- Fits mattresses from 6 to 18 inches deep
- Brushed microfiber surface is described as soft and quiet
- Machine washable, with care instructions provided
Cons:
- The listed product size is queen
- Requires low-heat drying according to the care directions
Verdict: Choose SheRest if you have a queen foam mattress and need a waterproof cover with a stated deep-pocket range and clear washing guidance.
NORTHERNFARE Tencel: Cooling-Focused Protection in King Size
This king-size protector uses a Tencel top layer, a waterproof barrier, and an 18-inch-deep pocket. The combination is designed to keep liquid away from the mattress while offering a breathable, moisture-wicking surface. It is listed for memory foam, pillow-top, and other mattress styles.
For a foam bed, the deeper pocket and all-around elastic skirt may help keep the fitted cover in place. NORTHERNFARE also describes the protector as noiseless and machine washable. The product description says it is OEKO-TEX 100 certified and hypoallergenic; shoppers with specific sensitivities may still want to check the listing for full material and care details.
This model’s main distinction is its king-size fit and cooling-focused Tencel surface. If you need another size, or would rather have a cotton or bamboo-derived fabric, one of the other picks may be a better match.
Pros:
- Waterproof design with a Tencel top layer
- Fits mattresses up to 18 inches deep
- Described as breathable, cooling, and noiseless
- Machine washable and dryer safe, according to the description
Cons:
- The listed size is king
- Cooling feel is a design claim, not a guarantee of a particular sleep temperature
Verdict: NORTHERNFARE is a strong fit for king-size foam beds if you want waterproof coverage, a Tencel surface, and a stated deep-pocket fit.
Sleepsteady Tencel: Soft, Cooling-Style Protection for Queen Beds
The Sleepsteady protector is a queen-size waterproof cover with a Tencel top layer. Its description highlights moisture wicking and a cool, soft feel, along with a stretchy side skirt designed for mattresses up to 18 inches deep. It is listed as suitable for different mattress types, including foam.
Like the NORTHERNFARE option, it targets shoppers who want a smoother, cooling-style surface as well as liquid protection. Its listed fit and size are helpful details, but the product information does not specify a particular waterproof membrane material. If that detail matters to you, check the product listing before choosing.
The description also states that the protector can be returned within a 90-night trial period and that manufacturer defects are covered for up to five years. Confirm the current terms on the listing, since guarantee details may be subject to conditions.
Pros:
- Waterproof protection for spills and accidents
- Tencel surface is described as soft, breathable, and cooling
- Fits mattresses up to 18 inches deep
- Queen size suits many foam beds
Cons:
- Only the queen size is specified in the supplied product details
- The waterproof barrier material is not identified in the supplied description
Verdict: Sleepsteady is a good option for a queen foam mattress if you value a Tencel top and want a stated deep-pocket fit with waterproof protection.
How to Choose a Mattress Protector for a Foam Mattress
Decide How Much Liquid Protection You Need
Start by matching the protection level to your household. A water-resistant cover like Kool-Flow may be enough for routine moisture protection, but it is not described as fully waterproof. If you need a stronger barrier against spills, sweat, or accidents, look for a model explicitly described as waterproof, such as the PlushDeluxe, SheRest, NORTHERNFARE, or Sleepsteady.
Check the Mattress Size and Depth
A fitted cover needs to match both your mattress size and its depth. A pocket that is too shallow may be difficult to fit, while a loose cover can shift or bunch. Among these picks, SheRest states a depth range of 6 to 18 inches, and the PlushDeluxe, NORTHERNFARE, and Sleepsteady descriptions specify a maximum depth of 18 inches. Check the listing for the right size and fit details for your bed.
Consider How the Surface May Feel
Foam mattresses can feel different once you add a cover, so pay attention to the top fabric and construction. These options use bamboo-derived viscose, organic cotton, brushed microfiber, or Tencel. The descriptions emphasize soft or breathable surfaces, but comfort is personal. If keeping the mattress’s existing feel is important, consider a thinner protector rather than a padded mattress pad.
Think About Heat and Breathability
If you tend to sleep warm, look for a protector described as breathable or moisture-wicking. PlushDeluxe, SheRest, NORTHERNFARE, and Sleepsteady make those types of claims, and the Tencel options are positioned as cooling choices. These features may help the cover feel less clammy, but they cannot guarantee a specific temperature or change the underlying feel of your mattress.
Look for Quiet Construction
A waterproof layer can sometimes make noise when you move. If sound is a concern, prioritize products described as noiseless or quiet. PlushDeluxe, SheRest, and NORTHERNFARE specifically emphasize quiet use. Keep in mind that the product description is not a substitute for checking the return policy if you are particularly sensitive to fabric noise.
Review the Care Instructions
A protector is easier to maintain when you know how to wash and dry it. SheRest specifies cold-water washing and tumble drying on low. NORTHERNFARE describes its cover as machine washable and dryer safe, while the Kool-Flow description says it is washable. Follow the care directions on the product listing and label to help preserve the fabric and protective layer.
Frequently Asked Questions
Can I use a waterproof protector on a foam mattress?
Yes. Several options in this guide are described as suitable for memory foam or other foam mattresses. Check the protector’s size and pocket depth against your mattress before ordering.
Will a mattress protector change how my foam bed feels?
It may add a layer between you and the mattress, so the feel can vary by fabric and construction. These products are protectors rather than thick toppers, but no cover can be guaranteed to leave every mattress feeling exactly the same.
Is water-resistant the same as waterproof?
No. Water-resistant fabric is intended to resist some moisture, while a product described as waterproof is designed to block liquids more fully. If you need protection from spills or accidents, choose a model explicitly described as waterproof.
Which option is listed for the deepest mattresses?
SheRest specifies a fit for mattresses from 6 to 18 inches deep. PlushDeluxe, NORTHERNFARE, and Sleepsteady also state that they fit mattresses up to 18 inches deep.
Which protector may suit a hot sleeper?
NORTHERNFARE and Sleepsteady emphasize Tencel surfaces and cooling or moisture-wicking features. PlushDeluxe and SheRest also describe breathable designs. These are product claims, so individual comfort may vary.
Can I wash these mattress protectors?
The supplied descriptions identify the Kool-Flow as washable, SheRest as machine washable, and NORTHERNFARE as machine washable and dryer safe. For the other options, check the product listing and care label for exact washing and drying instructions.
What is the best overall choice for a foam mattress?
For a broadly useful balance of waterproof protection, a quiet design, and compatibility with foam beds, PlushDeluxe is a strong starting point. If you want a Tencel surface, consider NORTHERNFARE for a king bed or Sleepsteady for a queen bed. Choose Kool-Flow only if water resistance meets your needs.
Final Recommendation
The best mattress protector for your foam bed depends on the protection level, fabric, and fit you need. PlushDeluxe is a versatile waterproof pick described as quiet and suitable for foam mattresses. Choose SheRest for a queen bed with a stated 6-to-18-inch fit range, or consider a Tencel option if a cooling-focused surface matters most. If you only need water resistance and prefer organic cotton, Kool-Flow is the alternative to consider.
