Its certified 3-sided zipper lock ensures no pest entry or escape, while the smooth polyester fabric keeps you cool and comfortable. Machine washable and backed by a 10-year warranty, it’s a smart investment for health-conscious sleepers seeking lasting mattress protection. ## Description Protect either mattress or box spring. Bed bug and dust mite infestations are serious problems that can cause a variety of health concerns including asthma, eczema and allergies. Aller-Zip mattress and box spring encasements provide an effective barrier to infestation. Because treatments cant reach the core of an already infected mattress and box spring, they usually need to be disposed of - but no longer. Aller-Zip protects your mattress investment and most importantly, your health. Its smooth fabric toplayer is soft and comfortable under your sheets. Protects against leaks or tears for 10 years or the factory will replace at no cost. Review: Great experience so far! - Hi! This is a review for the queen sized mattress protector with a depth of 11-18" used on a mattress of 13.5 inch depth. So far this has been a great experience! I washed the cover prior to use, it held up very well from being washed and dried, the stitching looks durable and well sewn. There is a zip which runs along three sides of the mattress cover, over top of the zipper line is a bit of fabric that helps cover the zipper fully which I think was a nice touch, the top area is enclosed. It was a pretty quick installation, no need to tip mattress on the side, just slide it a bit off bed to make getting the top portion onto the mattress a bit easier. As a petite person I was able to install this in 6-7 minutes by myself and fairly easily which was very surprising and pleasant! The texture is surprisingly soft, though not sure I'd sleep on it without a fitted sheet over top as it's soft but still feels synthetic, maybe a bit like a sturdy polyester. I put over the top a blanket top mattress protector fitted sheet then over that my fitted sheet. Having now slept on it last night I felt pretty comfortable, it did feel a little warmer -- like maybe it traps heat a bit more but that could also be in my head (haha) as it's so barely perceptible that it really isn't bothersome and think I'll likely not notice a difference in a week. I don't discern any crinkling sounds like plastic, haven't noticed any air bubbling up inside, overall I really can't tell it's on there except the very slight heat retention but I would say, I prefer my bed sheet being a bit looser, it may respond differently if the mattress protector is super tight in fit and the bed sheet also has similar fit? To my eyes, the bed looks nearly exactly the same as before. I'm not sure if I'd assume this to be completely waterproof but would definitely expect this to repel water well, if I spilled a considerable amount of liquid on here I think I'd take off the mattress protector quickly and check the mattress then let the mattress protector dry fully before placing it on bed again. That said, I was not strictly looking for a 100% waterproof cover as I was something not too plastic sounding and would be a good protection for dust and any possible pests, all of which I have found in this mattress protector so far. Overall this has been a really great experience! Thank you Protect-A-Bed for a great product and desertcart for offering this at a great discounted price! :D Review: Bought two - for mattress and boxspring - love it. Much better than competition! - I bought two sizes of these Allerzip Smooth Encasements for a Queen bed. A smaller one, 7-12 inches deep, fit perfectly over a 9" boxspring. A larger one, 12-18 inches deep, fit perfectly over a 13" mattress. The fabric stretches, and it fit without sagging - not too tight, but also no extra fabric anywhere, just right. I'm very happy with this product. This was the best I could find among premium encasements that offered bugproof protection, and I shopped a lot, including looking at several competing encasements at Bed Bath & Beyond etc. AllerZip Smooth encasement was easy to install. The fabric is thick and sturdy (much sturdier and tighter weave than the other premium offerings I saw). The fabric is smooth, and it's quiet and sweat-free to sleep on. The quality (thickness, the tightness of the fabric weave and zipper, design of the lock) is much better than a $100+ premium encasement I bought at Sleepy's (that one disintegrated, was hot to sleep on, and did not have protective locks over zippers). I'm especially happy with the tightness and sturdiness of the fabric weave (especially when compared to what was offered for a similar or higher price at BBB). Installation was easy. However, some advice: 1) when installing on boxspring, put some duck tape on the metal corners of the boxspring, to protect the fabric of encasement; (those metal corners can be sharp as knives); 2) if using a metal bed, put some felt pads on the sharp edges of the bed; and 3) AllerZip encasement will trap anything inside - including AIR during installation; therefore, in order to avoid an air bubble, don't zip it fully before releasing (smoothing out) the trapped air. This is a very good product for what is needed (bugproof, allergy proof, quality). ## Features - All Panels 100% Polyester - Waterproof: Polyurethane film backing repels liquids like urine and sweat on all six sides. - Breathable Barrier Fabric: NOT hot to sleep on.

It is easier to put on with two people but you could probably manage with one if you absolutely had to. Bedbugs are such a pain to both try to prevent and to deal with if you have them. This is one tool that really helps and it is worth the money to have peace of mind that my mattress is protected from bedbugs. ## Frequently Bought Together - Protect-A-Bed AllerZip Smooth Allergy, Dust Mite & Bed Bug Proof 6-Sided Waterproof Mattress Encasement Or Box Spring Encasement, Queen 13-inch, white, full - Protect-A-Bed, AllerZip Pillow Protector, Zippered, Waterproof, 2-pack, Standard Size - Protect-A-Bed AllerZip Smooth Waterproof Mattress Protector, Machine Washable, King, 11-18 Inches --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/4180378-protect-a-bed-allerzip-mattress-encasement-11-18-height-waterproof](https://www.desertcart.jp/products/4180378-protect-a-bed-allerzip-mattress-encasement-11-18-height-waterproof) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-28*
