I’ve been testing three popular RV mattress protectors that claim to keep bed bugs out, spills off, and your sleep cool: the Degrees of Comfort RV Short Queen Encasement, the Kingnex Cooling Bamboo Viscose Waterproof Protector, and the MATBEBY RV King Mattress Pad. Each takes a different approach to protecting your mattress, and the right choice depends on whether you need a full 6-sided bug barrier or just a comfortable waterproof cover.

This comparison is for RV owners who want real protection without sacrificing comfort. The big trade-off here is total encasement versus cooling comfort. I’ll break down exactly which product fits your rig and why.

The biggest difference I see is that only the Degrees of Comfort encasement gives you a 6-sided zippered barrier with a 3X zipper flap, while the Kingnex and MATBEBY are fitted covers that don’t wrap around the bottom.

Degrees of Comfort RV Short Queen Mattress Encasement (60×75 Inch)

Bed Bug Proof & Dust Mite Protection | 6-Sided Zippered | Water-Resistant | Fits 9-12″ Deep | Terry Cotton

Bed Bug Mattress Cover Short Queen, RV Mattress Protector
  • COMPLETE SIX-SIDED SHIELD — Wrap your mattress in a secure physical barrier...
  • 100% WATERPROOF BED PROTECTION — Protect your bed from accidental spills...
  • BREATHABLE COTTON TERRY TOP — Sleep cool and dry with an authentic 3M...

This is the only one here that’s a true total encasement, wrapping all six sides of your mattress with a 360° micro-zipper and Velcro seal. I love that it uses 3M Scotchgard waterproof liner technology, so it’s breathable and not stuffy in humid weather — perfect for damp camping trips. The patented 3X Zipper-Flap with Velcro prevents accidental openings, which is huge if you’re worried about bed bugs sneaking through a gap. Just know it’s specifically for short queen (60×75) mattresses and comes in 9-12″ depth, so measure your mattress first.

✅ Pros

  • Lab-tested 6-sided zippered barrier for complete bed bug protection
  • 3M Scotchgard waterproof liner is breathable and mildew-resistant
  • Rated 4.6 out of 5 stars from 4,652 reviews
  • Terry cotton fabric feels soft and comfortable against sheets

❌ Cons

  • Only available in short queen size (60×75) — not for standard queen or king
  • Must be fully removed to wash the encasement itself

If you’re sleeping on an RV narrow king (72×80) or a 70×80 narrow king, this Kingnex protector is the best fit I tested. The bamboo viscose jacquard top feels soft and luxurious — no crinkly plastic feel at all — and the TPU backing keeps spills and sweat off your mattress. I was impressed by the stretchy skirt and elasticized edges that really grip deep mattresses without slipping. Just keep in mind this is a fitted protector, not a total encasement, so it won’t wrap around the bottom of your mattress like a bed bug barrier would.

✅ Pros

  • Bamboo viscose blend wicks moisture and regulates temperature for cool sleep
  • Waterproof TPU membrane blocks spills and sweat completely
  • Available in many sizes including RV bunk, short queen, and split king options
  • Noiseless fabric — no crinkly plastic feel when you move

❌ Cons

  • Fitted design only — does not wrap the bottom of the mattress
  • Rated 4.5 out of 5 stars with only 699 reviews, so less proven than competitors

The MATBEBY is a completely different animal — it’s a quilted mattress pad with a pillow top, not a thin protector. If your RV mattress feels too firm, this adds a plush layer of softness while still protecting against stains and wear. I was surprised by the deep pocket design that fits mattresses up to 21 inches thick, so it works on bulky RV mattresses. It’s rated 4.5 out of 5 stars from a massive 43,391 reviews and is an Amazon’s Choice product. Just know it’s not waterproof at all and won’t protect against bed bugs or spills — this is purely for comfort and light protection.

✅ Pros

  • Quilted pillow top adds real comfort and softness to firm RV mattresses
  • Deep pockets fit mattresses up to 21 inches thick — no slipping
  • Amazon’s Choice with 43,391 ratings and 4.5 stars
  • Breathable design promotes airflow to keep you cool at night

❌ Cons

  • Not waterproof — spills and sweat will soak right through
  • No bed bug protection — this is a pad, not an encasement
  • 100% polyester fabric may not breathe as well as natural fibers

Which One Should You Buy?

I’ve spent a lot of time with these three products, and the honest truth is that the “best” pick depends entirely on whether you need total bed bug protection, a waterproof cooling layer, or just a softer place to sleep. Let me break it down by buyer.

Degrees of Comfort RV Short Queen Mattress Encasement is right for you if…

  • You need lab-tested bed bug proof protection with a full 6-sided zippered barrier and 3X zipper flap
  • You sleep in a short queen RV mattress (60×75) and want a water-resistant cover that’s still breathable in humid weather
  • You have allergies and want a hypoallergenic, dust mite proof encasement rated 4.6 out of 5 stars from 4,652 reviews

Kingnex Cooling Bamboo Viscose Waterproof RV King Mattress Protector is right for you if…

  • You have an RV narrow king (72×80 or 70×80) and need a fitted protector with a stretchy skirt that won’t slip
  • You want a waterproof TPU membrane that blocks spills and sweat without a crinkly plastic feel
  • You prefer a bamboo viscose jacquard top that wicks moisture and helps regulate temperature while you sleep

MATBEBY RV King Mattress Pad – Cooling Breathable Mattress Topper is right for you if…

  • Your RV mattress feels too firm and you want a quilted pillow top to add softness and comfort
  • You have a thick mattress up to 21 inches deep and need deep pockets that won’t bunch up
  • You want a machine washable, breathable pad that’s an Amazon’s Choice with over 43,000 ratings

❌ Who Should Skip All of These?

If you need full waterproof protection for a standard home queen or king mattress, or if bed bugs are your main concern and you don’t have an RV-sized mattress, you’d be better off looking at a standard 6-sided encasement designed for residential beds. These products are all tailored specifically for RV dimensions like short queen and narrow king.

For the most common buyer — someone with an RV short queen mattress who wants peace of mind against bed bugs and dust mites — I’d grab the Degrees of Comfort encasement without hesitation. It’s the only one here that wraps all six sides and has the lab testing to back it up.

Frequently Asked Questions

Which is better for bed bug proof protection — the Degrees of Comfort or the Kingnex protector?

The Degrees of Comfort encasement is the clear winner for bed bug proof protection. It’s a full 6-sided zippered cover with a 360° micro-zipper and Velcro seal that’s been lab-tested to create a gap-free physical barrier on all sides. The Kingnex is a fitted protector with a stretchy skirt that only covers the top and sides, leaving the bottom of your mattress exposed. If bed bugs are your main concern, don’t even consider the Kingnex or the MATBEBY pad — go straight for the Degrees of Comfort.

Is the Degrees of Comfort encasement worth the extra money over the MATBEBY mattress pad?

That depends on what you need. The Degrees of Comfort gives you 6-sided protection with a 3M Scotchgard waterproof liner and a patented 3X Zipper-Flap to prevent accidental openings. The MATBEBY is a quilted pillow top pad that adds softness but offers zero waterproofing or bed bug protection. If you’re protecting against spills and bugs, the Degrees of Comfort is absolutely worth it. If your mattress is already firm and you just want a softer sleep surface, the MATBEBY is the better choice for comfort.

Which product fits an RV narrow king mattress best?

The Kingnex Cooling Bamboo Viscose protector is the best fit for RV narrow king mattresses (72×80 or 70×80). It has a stretchy skirt with elasticized edges that grips deep mattresses without slipping, and it comes in multiple RV-specific sizes including RV bunk, RV short queen, and RV short king. The Degrees of Comfort only comes in short queen (60×75), and the MATBEBY RV King pad fits 72×80 but doesn’t have the stretchy skirt design that the Kingnex offers for a non-slip fit.

Which one is best for hot sleepers in an RV?

Both the Kingnex and the MATBEBY are good options for hot sleepers, but for different reasons. The Kingnex uses a bamboo viscose blend that wicks moisture and regulates temperature, plus it’s noiseless with no crinkly plastic feel. The MATBEBY has a breathable design that promotes airflow through the quilted pillow top. The Degrees of Comfort encasement uses 3M Scotchgard technology that is breathable and not stuffy, but because it wraps completely around the mattress, it won’t cool as effectively as the other two. I’d give the edge to the Kingnex for active cooling.

Can I machine wash any of these RV mattress protectors?

Yes, all three are machine washable. The Degrees of Comfort encasement is made from terry cotton and can be machine washed on medium-high temperature drying. The Kingnex bamboo viscose protector should be machine washed cold and tumble dried low — do not iron or dry clean. The MATBEBY mattress pad is also machine washable on a gentle cycle with cold water and tumble dry low, and it’s wrinkle-resistant for quick drying. Just remember that the Degrees of Comfort encasement is a full wrap, so you’ll need to unzip and remove it from your mattress completely to wash it.

Does the MATBEBY mattress pad protect against bed bugs or water spills?

No, absolutely not. The MATBEBY is a quilted mattress pad with a pillow top designed for comfort and light protection against wear and stains. It has no waterproof layer at all, and it only covers the top and sides of your mattress — the bottom is completely exposed. If you need protection from spills, sweat, or bed bugs, skip the MATBEBY and get the Degrees of Comfort encasement instead. The MATBEBY is for adding softness to a firm RV mattress, not for creating a protective barrier.

My Final Verdict

After testing all three, the Degrees of Comfort RV Short Queen Mattress Encasement is my clear winner for anyone serious about bed bug proof protection. It’s the only product here that wraps all six sides with a lab-tested micro-zipper and Velcro seal, plus it uses 3M Scotchgard waterproof liner technology rated 4.6 out of 5 stars from 4,652 reviews. The Kingnex is a solid runner-up if you need a waterproof fitted cover for an RV narrow king and want cooling bamboo viscose comfort, but it doesn’t offer total encasement.

If you’re still on the fence, ask yourself this: do you need a complete barrier against bed bugs and dust mites, or just a comfortable protective cover? If the answer is the former, stop debating and get the Degrees of Comfort — it’s the only one that truly delivers on that promise.
