Start with a thin fitted protector for ordinary spills and sweat; move to five-sided or six-sided coverage only when you actually need more enclosure.

Essentials — best low-cost Yawnder option
Starting at $34 at the time checked, this is a simple Yawnder protector for shoppers whose main goal is keeping liquid off the mattress without paying for cooling treatments or an encasement.
Malouf Five Sided — best step-up coverage
Protects the top and sidewalls rather than just the sleep surface. It is useful when side spills, pets or kid-related accidents are a realistic concern.
DreamFit — best secure-fit option
Starts at $79 and uses DreamFit’s corner-band/elastic approach to reduce shifting. Pay the premium for fit, not because ordinary waterproofing requires a $79 protector.
Malouf Encase HD — full enclosure
Six-sided encasement is the right format when complete enclosure matters. It is overkill for someone who only wants to protect the top surface from a glass of water.
SafeRest Premium Cotton — another fitted option
SafeRest describes a cotton-terry surface with a membrane backing. Check coverage, pocket depth, price and return terms for the exact version and seller; Yawnder has not performed a comparative leak test for this guide.
What waterproof actually means
Most modern protectors use a thin membrane below a fabric face. The tradeoff is simple: thicker or less breathable barriers can hold more heat and sometimes change the feel of the mattress. The best protector is the least intrusive one that provides enough coverage for your household.
How to Choose the Right Fit
Measure your mattress from top to bottom, including an attached pillow top and any topper you intend to cover. Compare that measurement with the listed pocket depth or encasement depth range. A protector that is too tight can pull off during the night; excess slack can bunch beneath the sheet.
Check whether the waterproof membrane covers only the top or also the sides. A fitted skirt is not automatically waterproof. For a split king with independently moving mattresses, consider two appropriately sized Twin XL protectors.
When to use an encasement instead
A fitted protector is easier to remove and wash. An encasement surrounds all six sides and is better suited to bed-bug containment strategies or full allergen enclosure. See our protector vs encasement guide. For dust-mite concerns, compare the specific barrier and closure details in our allergy-focused protector guide.
Frequently asked questions
Are all fitted protectors waterproof on the sides?
No. Some have a waterproof top and a stretchy fabric skirt; others have a waterproof barrier on all five exposed sides. Check the exact product description.
Do encasements guarantee protection from bed bugs?
No single cover guarantees elimination of an infestation. Choose a product specifically rated for the purpose, install and inspect it according to its instructions, and seek professional pest-control advice when needed.
Can I return a protector to Yawnder after trying it?
Yawnder’s return policy lists protectors and other bedding as non-returnable. Check the written terms and dimensions before ordering; other sellers’ policies may differ.
