You want to guard your mattress against spills, sweat, dust mites, and bed bugs. A zippered mattress encasement wraps the entire mattress — top, bottom, and all four sides — in a sealed, waterproof skin (a liner that stops liquids from passing through). That is the only way to block pests from every angle, but many covers feel like sleeping on a crinkly plastic sheet. The best ones stay quiet, let air flow, and fit so snugly you forget they are there.
I’m Mohammad, founder of Calories Fit. This guide compares the manufacturers’ published specifications and patterns across verified customer reviews, so you see each pick’s real strengths and trade-offs without the marketing spin.
The right zippered mattress encasement must block liquids, zip completely shut, and feel no different than your bare mattress.
Our Picks at a Glance
How To Choose The Best Zippered Mattress Encasement
A fitted mattress protector (a cover that goes only over the top and sides) leaves the bottom of your mattress exposed. An encasement wraps all six sides, which is why pest control specialists often require one for bed bug treatment. Here is what to check before you buy.
Zipper Design and Seal
The zipper must run around the full perimeter (the entire edge of the mattress), not just one side. A Velcro flap (a strip of fabric that sticks to itself) over the zipper pull tab prevents the zipper from drifting open, so it blocks tiny gaps that bed bugs or dust mites could squeeze through.
Waterproof Membrane Material
Most encasements use a polyurethane (PU) (a common plastic lining) or TPU (thermoplastic polyurethane — a more flexible, quieter rubber-like liner) backing to stop liquids. A TPU layer tends to feel more flexible and quieter at night, while a basic PU lining can feel stiff or crinkly. For homes with kids or pets, a 100% waterproof rating is essential.
Fabric Feel and Breathability
The top fabric is what you sleep on. Brushed polyester (a smooth synthetic fabric) is common and generally quiet. Terry cloth (a looped cotton fabric like a towel) or bamboo-viscose tops feel softer and let air pass through better. Avoid anything labeled “vinyl” or “PVC” (plastic-based covers) if you sleep hot or dislike a slick, plasticky feel under your sheets.
Fitting Your Mattress Depth
Encasements list a depth range (how thick a mattress it fits), like “fits up to 15 inches” or “14 to 16 inches.” Measure your mattress thickness (the height from the top surface to the bottom, including any pillow top or topper) and pick a range that leaves you a few inches of extra room. A cover that stretches too tight will stress the zipper seams and may rip.

In‑Depth Reviews
1. Four Seasons Essentials King Size Zippered Encasement
Our pick — over 4.5★ from 800+ verified ratings; the strongest balance of quality and price.
The deep-pocket king that seals tight without feeling like a tarp.
You need a cover that fits a very thick mattress. This encasement handles mattresses from 16 to 20 inches deep — enough room for a thick pillow-top or an extra mattress topper. The full zipper (a zipper that runs around three sides) wraps around the mattress, and a Velcro flap covers the pull tab to keep the seal shut. The smooth polyester surface is soft and noiseless, and the polyurethane inner lining blocks liquids completely.
Owners consistently say it stays put without shifting and washes well without losing its shape. The 3-year limited warranty from Four Seasons Essentials adds confidence if the zipper or seam ever fails. At 3 pounds it is sturdy without being heavy, and the slightly slippery material actually helps slide the cover over a heavy mattress during installation.
Why it wins
- Fits the deepest mattresses on the market (up to 20 inches)
- Velcro zipper seal keeps the closure locked
- Machine-washable with no shrinkage reported
The trade-off
- Three-side zipper leaves a flap of loose fabric during install
- Single color (white) only — no dark or patterned options
The pick for deep mattresses: If your mattress is 16 inches or taller, this is the most secure fitting encasement you will find — the Velcro zipper seal guarantees no gaps.
skip it if: Your mattress is under 15 inches; you will have too much slack, and the zipper flap may bunch under the sheets.
2. WINKAURA Queen Waterproof Zippered Encasement
The terry-cloth top makes this feel like a regular cotton sheet instead of a plastic bag.
What sets this encasement apart is the top layer of terry cloth — a soft, looped cotton blend that breathes better than standard polyester. The TPU waterproof membrane stops spills and sweat without feeling crinkly. Buyers report that it stays quiet at night and fits queen mattresses 13 to 15 inches deep without bunching.
The 3-sided invisible zipper includes a Velcro guard over the pull, and the whole cover can be removed in under 60 seconds. After two years of heavy use, several owners note the zippers still work and the fabric has not ripped — a stronger durability record than the Four Seasons Essentials has. For the price, it is a rare combination of softness and leakproof confidence.
Who this fits: Anyone sleeping on a 13-to-15-inch queen mattress who prioritizes a cotton-like feel over a slick polyester surface.
The caution: The terry top may retain a bit more heat than a thin polyester cover, so very hot sleepers should consider a bamboo or mesh option.
Best for comfort seekers: The cotton terry top is the softest surface in this lineup and still passes the 100% waterproof test.
Think twice if: Your queen mattress is thinner than 12 inches — the 13–15 inch range leaves extra fabric that can wrinkle.
3. Utopia Bedding King Size Zippered Encasement
The most-reviewed encasement on the market for good reason — it simply works.
With over 130,000 ratings, this is the encasement the crowd trusts. The wrap-around zipper fully encases a king mattress up to 15 inches deep, and the non-crinkling design keeps it quiet through the night. The smooth knitted polyester surface lays flat without shifting, and the waterproof polyurethane layer has been tested by thousands of owners.
The quality and fit each earn over 3,000 mentions from buyers, who also praise the easy installation — though two people help with a king. Some owners mention variable durability after many wash cycles, and the mixed feedback on water resistance suggests very heavy spills may reach the seams if the cover is stretched tight.
Why 130k+ buyers chose it
- Proven track record with a 4.6-star average across tens of thousands of owners
- Soft polyester surface with no crinkle noise
- Machine washable and holds shape after washing
The honest catch
- Durability is mixed — some customers note rips after extended use
- Fits up to 15 inches only; thicker mattresses need a different model
Safe pick for most: The combination of proven performance, quiet fabric, and low entry price makes this the easiest recommendation for standard king mattresses up to 15 inches.
Skip it for: Extra-thick mattresses (over 15 inches) or anyone who needs a plush terry or bamboo surface.
4. Linenspa Zippered Waterproof Mattress Encasement (Queen)
A featherlight 16-ounce encasement with a 10-year warranty that almost nobody needs to use.
At only 16 ounces (one pound), this is the lightest encasement in the roundup, but it still wraps all six sides in a soft brushed polyester shell. The waterproof polyurethane lining is quiet and effective, with no seepage reported in user tests. The zipper runs around the full perimeter and seals tightly enough for bed bug protection.
Linenspa backs it with a 10-year limited warranty against manufacturer defects, which is rare at this price point. The main limitation is the 12-inch depth cap, so it will not work on thicker pillow-top or deep Euro-top mattresses. Some reviewers point out a slight crinkle sound when new, which fades after the first wash.
Who it suits: Dorm beds, guest rooms, and RVs where mattresses are standard 8–12 inches and weight savings matter.
The limitation: If your queen mattress is 13 inches or deeper, skip this one and go for a model with a higher depth range.
Best for standard-depth mattresses: At 16 ounces it adds no bulk, and the 10-year warranty is the longest in this guide.
Not for: Thick pillow-top mattresses over 12 inches, or anyone who wants a softer fabric top.
5. Utopia Bedding Premium Zippered Twin XL 2-Pack
Two full encasements for bunk beds, guest twins, or backup protection at once.
This twin XL 2-pack is the only multi-pack in the guide, giving you two identical encasements in one purchase. Each measures 39 x 75 x 15 inches — a standard twin XL size — and uses TPU fabric backing (a flexible, quiet waterproof layer) for waterproofing. Buyers dealing with bed bugs especially like having a spare cover ready to swap while one is being washed.
The polyester fabric is soft on top with no crinkle noise, and the zipper runs around all sides for full 360-degree coverage (all six sides sealed). The main drawback is the 12-inch depth limit, which may be tight on thicker twin XL mattresses.
Use case: Ideal for kids’ rooms, vacation homes, or rental properties where you need to protect two identical twin mattresses at once.
The catch: The 12-inch depth is relatively shallow — measure your mattress before ordering.
Budget twin solution: Two covers in one box at a price that beats buying singles.
Look elsewhere if: You need a single king or queen cover, or your twins are deeper than 12 inches.
6. Kingnex Waterproof Zippered King Size Encasement
The quietest knitted polyester surface in the test — no crinkling, no rustling, no noise.
This Kingnex encasement uses a smooth knitted polyester top that owners consistently describe as noiseless. The membrane coating on all six sides stops liquids while allowing airflow, reducing heat buildup. It fits king mattresses ranging from 11 to 15 inches deep — a narrower range than the Four Seasons Essentials.
The zipper uses fine teeth for a clean seal, and buyers who run Airbnbs say this is the best-fitting cover they have tried across multiple brands. One caveat: on mattresses at the shallow end of the range (11 inches), the cover can feel a bit loose around the sides. It washes well, and several owners note no loose threads or seam failures after repeated machine cycles.
Why it stands out
- Breathable membrane reduces heat — better for hot sleepers
- Noiseless construction with no plastic crinkle
- Fine-tooth zipper seals tightly
Small issues
- Loose fit on very thin (11-inch) mattresses
- Single color white only
For quiet sleep: If the sound of a crinkly protector wakes you up, this is the smoothest, quietest option for king mattresses 11 to 15 inches deep.
Skip if: Your mattress is under 11 inches — the excess fabric will bunch.
7. Four Seasons Essentials Full Size Cotton Terry Encasement
A 100% cotton terry top that breathes like a regular sheet, with a waterproof backing underneath.
Unlike most encasements that use polyester, this one from Four Seasons Essentials features a cotton terry top layer (a looped cotton fabric, like a soft towel). It feels absorbent against the skin and eliminates the sweaty sensation some plastic-backed covers create. The full zipper runs around three sides and includes a Velcro pocket for the pull tab. It fits full mattresses from 9 to 16 inches deep.
Installation is easier with two people on a king size, but this full-size version is manageable solo. The zipper quality draws mixed feedback — most find it smooth, but a small number of shoppers say the zipper breaking after extended use. The 3-year limited warranty covers workmanship defects, so any issue within that window is replaceable.
The natural fabric advantage: Cotton terry is more breathable than polyester, making this a strong choice for allergy sufferers who want fewer synthetic layers.
The risk: The zipper’s construction is the most common complaint, so avoid forcing it over a too-tight mattress.
Best natural-feel pick: The cotton terry top is class-leading for breathability and softness among full-size encasements.
Consider alternatives if: You want the absolute strongest zipper — the polyester models in this guide have fewer zipper-related complaints.
8. Mattressentials Queen Zippered Protector (14″–16″ Depth)
Specifically built for deeper queen mattresses that most standard encasements leave exposed.
This Mattressentials encasement targets queen mattresses between 14 and 16 inches deep — the range that many budget covers miss, including the Linenspa which only goes to 12 inches. The stretchable polyester blend fabric zips around three sides with a Velcro seal, and the polyurethane lining is 100% waterproof (stops all liquids). Owners note it fits 15-inch mattresses with ease and does not retain heat.
The zipper teeth are tight and run smoothly, which buyers report gives confidence in bed bug prevention. After many washes the cover holds up without pilling or seam splitting, though a handful of owners mention durability concerns over the long term. The 3-year warranty covers manufacturing defects and adds a safety net that cheaper covers lack.
Why this depth matters
- Engineered for deep 14–16 inch queen mattresses — a common missing size
- No heat retention reported even after long use
- Zipper teeth seal tightly for pest prevention
The downside
- Long-term durability is mixed in reviews
- Limited to queen size only
Purpose-built for deep queens: If your queen mattress is 14 inches or deeper, this fits better than a generic cover designed for 12-inch mattresses.
Not for: Standard 10–12 inch queens — you will have too much loose fabric.
9. Slumberfy Full Size Bamboo Zippered Encasement
A bamboo-viscose top that feels cool and smooth, backed by a lifetime warranty.
Slumberfy uses 60% bamboo fiber blended with polyester for the top layer — a fabric that feels noticeably softer and cooler than standard polyester. The 360-degree zipper (a zipper that runs around the entire top edge) runs around the mattress, making installation fast and removal easy for washing. The waterproof lining stops spills, and the bamboo fabric is naturally hypoallergenic.
The zipper lies flat under sheets and allows unzipping just the top half for washing without disturbing the bottom seal. Buyers who used it for camper mattresses and mattress toppers praise the perfect fit for 9-to-12-inch depths. The lifetime warranty is the most generous in this guide, though one owner reported a zipper failure that was quickly replaced.
Why the lifetime warranty matters: Slumberfy states they will replace the cover if it fails, making this a buy-it-for-years option according to the brand.
Size limitation: Only available in standard depths (9–12 inches), so it does not fit thick pillow-top mattresses.
Best sustainable pick: The bamboo top is cool and skin-safe, and the lifetime warranty is class-leading.
pass on it if: Your full mattress is deeper than 12 inches — you need a model with a higher depth range.
Understanding the Specs
Waterproof Membrane (PU vs. TPU)
A polyurethane (PU) lining (a standard plastic layer) is the common waterproof barrier inside most encasements — it stops liquids but can feel stiff or crinkly when new. TPU (thermoplastic polyurethane — a more flexible, rubber-like plastic) is a more flexible alternative that stays quieter at night and resists cracking over time. Both are 100% waterproof (they stop all liquids from passing through); the main difference is feel and durability.
Zipper Coverage and Closure
A full 360-degree zipper (a zipper that goes all the way around the mattress edge) wraps around the entire mattress perimeter and is the only design that truly seals the mattress on six sides. Some encasements use a three-side zipper with a sealed bottom, which still provides a complete seal but may leave a flap of fabric during installation. A Velcro guard over the zipper pull prevents the zipper from slipping open and closes any tiny gaps where bed bugs could enter.
