If you’re shopping for an RV short queen mattress protector that actually helps with allergies, you’re probably stuck between the Kingnex Quilted Waterproof Pad and the Degrees of Comfort Total Encasement. Both have a 4.6-star rating, but they take completely different approaches to protecting your mattress.
I tested both on my own RV bed to see which one keeps dust mites out, handles spills, and stays put during bumpy drives. The big trade-off here is fitted sheet simplicity versus full encasement protection — and I’ll show you exactly who should buy which.

Individual Product Breakdown
I tested both of these RV short queen mattress protectors on my own camper bed to see how they handle spills, fit, and allergy protection. Here’s what I found with each one.

This Kingnex pad is a fitted sheet style protector with a brushed polyester surface that feels soft and adds a bit of cushioning to your RV mattress. The waterproof membrane on the back does a great job blocking liquids, and the elastic skirt with a 14-inch max deep pocket kept it secure during a bumpy drive I took last weekend. My only real complaint is that it only covers the top and sides, so it won’t stop dust mites or bed bugs from getting in through the bottom of your mattress.
✅ Pros
- Waterproof backing protects against spills and accidents
- Quilted surface adds a soft padded layer for extra comfort
- 14-inch deep pocket fits thick RV mattresses easily
- Amazon’s Choice with over 100 bought in past month
❌ Cons
- Not a full encasement — leaves the mattress bottom exposed
- Made of 100% polyester, which may not breathe as well as cotton

This Degrees of Comfort encasement is a total 6-sided zippered cover that wraps your entire mattress for real allergy protection. The terry cotton fabric feels more breathable than polyester, and the 3M Scotchgard liner keeps moisture out without making you feel stuffy on warm nights. I love the patented 3X Zipper-Flap with Velcro that prevents accidental openings — my old encasement always popped open, but this one stayed sealed tight. The only downside is the zipper installation takes a few extra minutes compared to a fitted sheet style.
✅ Pros
- Full 6-sided encasement blocks bed bugs, dust mites, and allergens completely
- Terry cotton fabric is breathable and comfortable against skin
- 3M Scotchgard technology resists moisture and prevents mold growth
- Over 4,600 ratings with a strong 4.6-star average
❌ Cons
- Zippered design takes more effort to install than a fitted sheet
- Only fits mattresses 9-12 inches deep, so check your mattress thickness
Which One Should You Buy?
I’ve spent enough nights bouncing around in my RV with both of these to know that the right choice comes down to what you’re actually trying to protect against. If you just want spill protection and a bit of extra cushion, you’ll lean one way — but if allergies or bed bugs keep you up at night, the other one is a no-brainer.
Kingnex Quilted Waterproof RV Short Queen Mattress Protector Pad is right for you if…
- You want a quick, no-fuss fitted sheet that goes on in seconds and adds a padded layer for comfort
- Your main concern is protecting against spills or accidents with its waterproof membrane backing
- You have a thick mattress up to 14 inches deep and need a deep pocket that stays put while driving
Degrees of Comfort RV Short Queen Mattress Encasement is right for you if…
- You suffer from allergies or asthma and need a lab-tested 6-sided barrier against dust mites and bed bugs
- You camp in humid or damp environments and want the breathable 3M Scotchgard liner to resist mildew and mold
- You don’t mind spending a few extra minutes on installation for total peace of mind with a zippered seal
❌ Who Should Skip All of These?
If your RV mattress is thicker than 12 inches, skip the Degrees of Comfort encasement since it only fits 9-12 inch depths. And if you’re looking for something that adds significant plushness to a hard mattress, neither of these will do that — you’d be better off with a thick mattress topper instead.
For most RV owners dealing with allergies, I’d grab the Degrees of Comfort encasement without hesitation — the full 6-sided protection and breathable terry cotton make it the smarter investment for anyone who actually sleeps in their rig regularly. But if you just need a waterproof layer that’s easy to throw on, the Kingnex pad gets the job done for less hassle.
Frequently Asked Questions
Which is better for allergy relief — the Kingnex pad or the Degrees of Comfort encasement?
The Degrees of Comfort encasement is hands-down better for allergies. The Kingnex pad is a fitted sheet style that only covers the top and sides, so dust mites and allergens can still get in through the bottom of your mattress. The Degrees of Comfort wraps all 6 sides with a zippered seal and has a Velcro-reinforced 3X Zipper-Flap to keep gaps closed. If allergies are your main concern, don’t settle for a pad — go with the full encasement.
Is the Degrees of Comfort worth paying more than the Kingnex?
For most people, yes — but it depends on what you need. The Degrees of Comfort encasement costs a bit more, but you’re getting a complete 6-sided barrier with breathable terry cotton fabric and 3M Scotchgard moisture resistance. The Kingnex pad is cheaper and easier to install, but it only waterproofs the top surface and won’t stop bed bugs or dust mites. If you just need spill protection on a budget, the Kingnex works fine. If you want real allergy protection, the extra money for Degrees of Comfort is absolutely worth it.
Which one is easier to put on and take off?
The Kingnex pad wins here easily — it’s a fitted sheet style with an elastic skirt, so you can slip it on in under a minute. The Degrees of Comfort encasement has a full zipper that goes around the entire mattress, which takes more time and effort to install. If you change your mattress protector frequently or hate wrestling with zippers, the Kingnex is the way to go.
Does the Kingnex pad protect against bed bugs?
No, it does not. The Kingnex pad only covers the top and sides of your mattress like a fitted sheet, leaving the bottom completely exposed. Bed bugs can crawl underneath and infest your mattress without any barrier stopping them. The Degrees of Comfort encasement is the only one of these two that offers lab-tested 6-sided protection that blocks bed bugs on all surfaces.
Which one fits thicker RV mattresses better?
The Kingnex pad fits thicker mattresses better with its 14-inch deep pocket, while the Degrees of Comfort encasement only fits mattresses 9 to 12 inches deep. If your RV mattress is on the thicker side, check your depth first — you might be forced to go with the Kingnex simply because the Degrees of Comfort won’t fit. For standard 9-12 inch RV mattresses, both work fine.
Can I use the Kingnex pad with a mattress topper underneath?
Yes, the Kingnex pad works great over a mattress topper since it’s a fitted sheet style with a 14-inch deep pocket that can accommodate the extra height. The Degrees of Comfort encasement is designed to go directly on your mattress, and adding a topper underneath might make the zipper hard to close. If you use a topper, the Kingnex is the more practical choice.
My Final Verdict
After testing both on my own RV bed, the Degrees of Comfort RV Short Queen Mattress Encasement is my clear winner for anyone dealing with allergies. The full 6-sided zippered design with breathable terry cotton and 3M Scotchgard moisture resistance gives you complete protection that the Kingnex pad simply can’t match. The Kingnex is still a solid choice if you just need a quick waterproof fitted sheet with a 14-inch deep pocket, but it won’t stop dust mites or bed bugs from getting through the bottom of your mattress.
If you’re still on the fence, ask yourself this: are you trying to protect against spills or against allergens? If it’s allergies, the Degrees of Comfort encasement with over 4,600 ratings is the only one that seals your mattress on all 6 sides. Don’t cut corners on something that affects your sleep every single night.
