5 Mattress Encasements Under $35 for Allergy Season

Allergy season hits different when you realize your mattress might be part of the problem. The average mattress collects dust mites, dead skin cells, pet dander, and moisture over time — and if you're waking up stuffy or sneezy, a mattress encasement is one of the most effective and affordable fixes you can make. We're not talking about those crinkly plastic covers from the '90s. Today's encasements are soft, breathable, and completely undetectable under your sheets.

A good encasement fully zippers around your mattress (unlike a fitted protector that only covers the top), creating a barrier against allergens, bed bugs, and liquid spills on all six sides. For under $35, you can protect a mattress that cost you hundreds — or thousands — and extend its life by years. Here are five that sleep comfortably and actually do their job.

Which Mattress Encasement Do Allergists Recommend?

The SafeRest Premium Zippered Mattress Encasement is the #1 best-seller on Amazon for a reason — it's hypoallergenic, waterproof on all sides, and uses an inverted zipper with Micro-Zipper technology that blocks even the smallest dust mites and bed bugs. Queen size runs about $30.

SafeRest has been the default recommendation from allergists and pest control professionals for years. The cotton terry surface feels like a regular fitted sheet — you genuinely can't tell there's a protector on your mattress. It fits mattresses up to 12 inches deep (they also make a deep pocket version for thicker mattresses). Machine washable, tumble dry low. It's the safe choice in every sense.

What's the Best Waterproof Encasement That Doesn't Feel Plastic?

The Utopia Bedding Zippered Mattress Encasement uses a polyester knit fabric with a TPU waterproof layer that blocks all liquids without the crunchy, hot feel of vinyl. At around $18 for a queen, it's the best value on this list.

This is the encasement for people who've been burned by waterproof covers before — the ones that made you sweat and rustled every time you moved. The Utopia version is nearly silent and breathable enough for year-round use. The zipper runs along three sides for easy on/off, and the stitching is tight enough to keep out microscopic allergens. For $18, it's genuinely hard to find a reason not to protect your mattress.

Do Bed Bug Proof Encasements Actually Work?

The Linenspa Zippered Mattress Encasement is specifically lab-tested for bed bug protection — the zipper has no gaps, the fabric pore size is too small for bugs to pass through, and the seams are reinforced to prevent tearing. It's about $22 for a queen.

If bed bugs are your primary concern (or you just want the peace of mind), this is the encasement to get. The SureSeal zipper closure eliminates the gap that bugs can exploit in cheaper encasements. The fabric is a smooth polyester that stays cool and doesn't pill after washing. It's thinner than the SafeRest, so it works well on memory foam mattresses where you don't want to add bulk that changes the feel.

Is There a Bamboo Mattress Protector That Feels Luxurious?

The PlushDeluxe Bamboo Mattress Encasement uses a bamboo-derived rayon surface that's naturally cooling, moisture-wicking, and softer than cotton — and at $34, it's the most comfortable option under $35. It feels more like a premium sheet than a protector.

Bamboo fabric has a natural temperature-regulating quality that hot sleepers will appreciate. It wicks moisture away from your body instead of trapping it like synthetic waterproof layers can. The waterproof barrier is still there (TPU membrane underneath), but the sleeping surface feels noticeably cooler and softer than polyester options. If comfort is your top priority alongside protection, this is the upgrade worth making.

What About a Hypoallergenic Encasement for Sensitive Skin?

The SureGuard Mattress Encasement is OEKO-TEX certified (tested for harmful substances), completely free of vinyl, PVC, and phthalates, and designed specifically for people with chemical sensitivities or eczema. Queen size is about $28.

The SureGuard certification matters if you react to the chemicals found in many waterproof mattress covers. The 100% waterproof membrane uses no harsh materials, and the surface fabric is a soft cotton blend that won't irritate sensitive skin. It comes with a full 10-year warranty and a 30-day money-back guarantee, which tells you the company stands behind it. The zipper is velcro-sealed for extra protection against dust mites.

Quick Tips for Mattress Encasements

• Always wash your encasement before first use to soften the fabric and activate the waterproof layer
• Wash every 1-2 months on gentle cycle with cold water — hot water can degrade the waterproof membrane over time
• If you have a mattress deeper than 12 inches, double-check the pocket depth before ordering — most standard encasements max out at 12"
• Put your encasement on BEFORE your fitted sheet — it's a base layer, not a replacement for sheets
