An extra-thick waterproof mattress pad can add a cushioned layer while helping protect your mattress from spills, sweat, and everyday accidents. The right choice depends on your mattress size and depth, how plush you want the surface to feel, and whether the pad’s care instructions fit your routine. These three options offer different combinations of fill, fabric, fit, and waterproofing; note that one is designed for a full bed, while the others are queen-size choices.

Our Picks: Best Extra Thick Waterproof Mattress Pad reviews
MASVIS: A plush queen-size pad with a bamboo-derived cover
This MASVIS topper pairs a soft cover made from viscose derived from bamboo with a fluffy down-alternative fill. Its queen-size dimensions are 60 by 80 inches, and the pocket is designed for mattresses between 8 and 21 inches thick. That broad depth range may help it fit beds with taller profiles, though measuring your mattress is still a good idea.
The fill uses 5D and 7D fibers, which the product description says are arranged to create a resilient, cushioned structure. A waterproof layer adds protection against spills and accidents. The combination makes this a practical pick if you want more padding than a thin protector provides, without switching to a foam topper.
It is machine washable on a gentle cycle and can be tumble-dried on low heat. One limitation is that the product details do not specify a fill weight or explain the construction of the waterproof layer, so it is harder to compare its cushioning and protection directly with options that provide those details. It is also queen-size only in the supplied product information.
Pros:
- Queen-size surface with a stated 8–21-inch mattress fit
- Bamboo-derived viscose cover and fluffy alternative fill
- Combines cushioning with waterproof protection
- Gentle machine washing and low-heat tumble drying are supported
Cons:
- Product details do not state the fill weight or waterproof-layer material
- The listed size is queen only
Verdict: Choose the MASVIS if you want a cushioned queen-size pad with a soft bamboo-derived cover and straightforward wash care; compare its fit and thickness with your mattress before ordering.
Bedsure: A deep-pocket waterproof pick for full beds
The Bedsure is the only full-size option in this group, so it is the natural match for a full bed rather than a queen. Its 800 g Blendtek+ fiber fill is intended to balance softness and support. A quilted box design helps keep the filling distributed, while the five-layer construction and mesh fabric around the sides are designed to support airflow.
A TPU waterproof layer provides the moisture barrier, and a 21-inch deep pocket with stretchy elastic bands is intended to hold the pad in place on thicker mattresses. These fit details are useful if a standard fitted protector tends to shift on your bed. The product instructions say to place the top layer facing outward and the waterproof layer inward.
The main trade-off is size: it is not the right pick for a queen mattress. The description also does not give a specific noise level or a temperature guarantee, so hot sleepers who are sensitive to added layers may want to consider how much cushioning they prefer. The topper is listed as machine washable and dryable.
Pros:
- Full-size design for full mattresses
- 800 g Blendtek+ fill and quilted construction
- TPU waterproof layer
- 21-inch deep pocket with stretchy elastic bands
Cons:
- Not intended for queen-size beds
- Product details do not specify a noise level or measured cooling performance
Verdict: The Bedsure is the most fitting choice here for a full bed with a deep mattress, especially if you want a defined waterproof layer and a pocket designed for beds up to 21 inches thick.
NightHug: A cushioned queen option with a silent TPU backing
The NightHug is a queen-size topper with a bamboo cover, down-alternative fill, and a TPU backing. Its product description says the backing is waterproof and designed to stay quiet, while the cushioned fill provides a plusher surface than a basic mattress protector. The cover is described as breathable and moisture-wicking, but those terms should be treated as product claims rather than a guarantee that every sleeper will stay cool.
Its stated fit range is 8 to 21 inches, with elastic straps and a non-slip bottom intended to limit shifting. The cover is described as removable and washable, and the care instructions call for low-heat tumble drying. The listing also presents the topper as suitable for households with children or pets and for use with an RV queen mattress.
One important purchasing caveat: the supplied product data marks this item as unavailable. Availability can change, so check the product page before making a decision. Its description also makes broad claims about back-pain relief, but a mattress pad cannot guarantee relief; comfort and support depend on the sleeper and the mattress underneath.
Pros:
- Queen-size fit stated for mattresses 8–21 inches thick
- Bamboo cover with down-alternative cushioning
- TPU backing is described as waterproof and quiet
- Removable cover and low-heat drying instructions
Cons:
- Supplied availability data marks the item as unavailable
- Claims about cooling and pain relief may not apply to every sleeper
Verdict: The NightHug has a useful combination of queen-size cushioning and a stated quiet waterproof backing, but check availability first and treat comfort claims as personal rather than guaranteed results.
How to Choose an Extra Thick Waterproof Mattress Pad
Match the pad to your mattress size
Start with the exact mattress size. A full pad may not cover a queen mattress properly, and a queen pad can bunch or hang over the sides of a full bed. Of these picks, Bedsure is full-size, while MASVIS and NightHug are queen-size. Check the product page for the size you need before ordering.
Measure mattress depth, including any existing layers
Measure from the bottom edge of the mattress to its top surface, including any pillow top or mattress topper that will stay underneath the pad. MASVIS and NightHug state a fit range of 8 to 21 inches; Bedsure lists a 21-inch deep pocket. A pocket’s maximum depth is not the same as a promise of a perfect fit, so consider the mattress’s shape and the pad’s elastic design as well.
Decide how much cushioning you want
An extra-thick pad adds a soft layer, but it is not necessarily a substitute for a dedicated mattress topper. The MASVIS and NightHug descriptions emphasize fluffy down-alternative fill, while Bedsure specifies 800 g of Blendtek+ fiber. The product details do not provide directly comparable thickness measurements for all three. If you want only spill protection, a thinner protector may feel less noticeable; if you want added softness, look closely at the fill and construction.
Understand the waterproof layer
Waterproof pads generally use a barrier beneath the sleeping surface to help keep liquids from reaching the mattress. Bedsure specifies a TPU layer, and NightHug describes its backing as TPU. MASVIS describes the pad as waterproof but does not identify the barrier material in the supplied details. Follow the product’s orientation instructions, since placing the waterproof side incorrectly can reduce protection or comfort.
Consider fabric and sleeping temperature
MASVIS and NightHug use covers described as bamboo-derived or bamboo, while Bedsure highlights mesh around the sides and a five-layer design. Fabric, fill, bedding, and room temperature all affect how warm a bed feels. Terms such as “cooling” and “breathable” are helpful clues, but they do not ensure the same temperature experience for every sleeper.
Check care instructions before buying
Frequent washing can be important in homes with children, pets, or regular spills. The listed care directions vary: MASVIS calls for a gentle machine-wash cycle and low-heat drying; Bedsure says it can be machine washed and dried; NightHug describes a removable washable cover and low-heat tumble drying. Follow the instructions on the product itself, and make sure the pad will fit in your washer and dryer.
Look at how the pad stays in place
A deep pocket, elastic bands, straps, or a non-slip bottom can help reduce shifting, especially on a tall mattress or for sleepers who move around. Bedsure lists a 21-inch pocket with stretchy elastic bands, while NightHug describes elastic straps and a non-slip bottom. MASVIS lists a broad mattress-depth fit, but its supplied description gives fewer details about the fastening design.
Frequently Asked Questions
What is the difference between a mattress pad and a mattress protector?
A mattress pad usually adds some cushioning, while a protector focuses mainly on shielding the mattress. Some products combine both roles. These picks are described as cushioned toppers with waterproof protection, so they are intended to add padding as well as help guard the mattress.
Will an extra-thick waterproof pad fit a tall mattress?
It depends on the pad’s pocket depth and attachment design. MASVIS and NightHug list a fit range of 8 to 21 inches, and Bedsure lists a 21-inch deep pocket. Measure your mattress, including any layer beneath the pad, and compare that measurement with the product’s fit details.
Can a waterproof mattress pad feel warm?
It can, depending on the cover, fill, waterproof backing, bedding, and your own temperature needs. The listed products describe breathable or cooling features, but those descriptions cannot guarantee that a pad will feel cool to every sleeper.
Can I machine wash these mattress pads?
The supplied descriptions list machine washing for all three. MASVIS specifies a gentle cycle and low-heat tumble drying, Bedsure says machine wash and dry, and NightHug describes a removable washable cover with low-heat drying. Always follow the care label and product instructions.
Which option is right for a full-size bed?
Bedsure is the full-size choice in this comparison. MASVIS and NightHug are listed as queen-size options, so they are not the best fit for a full mattress.
Does a mattress pad guarantee relief from back pain?
No. A cushioned surface may feel more comfortable to some people, but comfort and back support depend on factors such as sleeping position, body, and mattress condition. Product claims about pain relief should not be taken as a guarantee.
Final Recommendation
For a queen bed, the MASVIS stands out as a practical option based on its bamboo-derived viscose cover, fluffy fill, stated 8–21-inch fit, and machine-wash care. For a full bed, choose the Bedsure, which specifies its fill weight, TPU waterproof layer, and deep-pocket design. The NightHug may suit shoppers seeking a queen-size pad with a stated quiet TPU backing, but the supplied availability data marks it unavailable, so check its listing before choosing it.
