Good Luck! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Satified with boxspring cover. *by on Reviewed in Canada 11 August 2020* It's very neat. Very white. Exceĺlent stitching and zipper. A little big for the boxspring. Not sure how thick my boxspring is, but at least 7inches possibly 1 or 2 inches more. Its about 10years old.Very fast delivery. Would definitely recommend. It's very easy to put on the matress. The hidden zipper goes all the way around 3 sides of the boxspring. ### ⭐⭐⭐⭐⭐ Great value *by on Reviewed in Canada 13 October 2020* Love this product. They stand up to their promise.Mattresses are expensive to begin with only makes sense to protect it. Especially if you live in an apartment building where all kinds of people come and go.....bring...taking....roaches....bedbugs....should I go on? ### ⭐⭐⭐⭐⭐ ... Is keeping our cat from clawing our new box spring *by on Reviewed in the United States 28 March 2015* This is an excellent product, even better than I was expecting. The zipper encompasses three of the four edges so that the "encasement" is extremely easy to put on -- and take off, should you want to. The zipper is also "tight," so much so that it's pretty much invisible once it's closed (preventing virtually anything, even very tiny things, from getting to your box spring).I bought this for the new box spring/foundation we've had, as I write, for barely two weeks. We bought the box spring and this encasement, along with a new mattress, for our home bed where bedbugs and other such creatures are not a problem. Instead, I got it in hopes that one of our cats -- who daily was using several corners of our previous nine-year-old box spring as a scratching post -- would stay away from this new box spring due to the VERY tight weave of this encasement.It's working. Roo was, from day 1, far less interested in it, and after systematically redirecting her away from it (she certainly knows what "NO!" means) she is now, instead, using the actual scratching post that's in the bedroom, as our other cats do. Roo is likely not very interested because she can't actually tear the encasement fabric or stick her claws into it in the (to her) same satisfying way she could into the previous box spring. If her claws were very sharp (we keep them trimmed) they might leave pin-point punctures the fabric (she's a small cat, with small claws), but this encasement's fabric is just not tearable. By extension, this encasement must certainly also work to keep out bedbugs, et al, as it's intended.Considering the unusual fabric and zipper, how well this is made, and how much good bedding materials cost these days, the price, I think, is also pretty reasonable. ## Frequently Bought Together - SafeRest Premium 9" Thick Box Spring Encasement - Waterproof - Breathable, Noiseless and Vinyl Free - Fits Up to 9" - TwinXL - SafeRest 100% Waterproof Twin XL Size Mattress Protector - College Dorm Size for Back to School - Machine Washable Cotton Mattress Cover for Bed - Perfect Bedding Airbnb Essentials for Hosts - SafeRest Zippered Mattress Protector - Premium 9-12 Inch Waterproof Mattress Cover for Bed - Breathable & Noiseless Washable Mattress Encasement - Twin XL --- ## 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.sg/products/66538833-saferest-twin-extra-long-xl-size-premium-waterproof-lab-certified](https://www.desertcart.sg/products/66538833-saferest-twin-extra-long-xl-size-premium-waterproof-lab-certified) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-04*
