Review: My trust has been earned - Mommy of two boys -5 and 3 years old. Both are twin mattresses but one is a 10 inch profile. Purchased a full size for the thinner mattress and a queen for the thicker mattress. The mattress pad will rip if my kids jump on their bed with the recommended size protector, which is why I sized up. This was trial and error, the first set of protectors I purchased ripped because they fit snug and there was no room, but the size up is working well! One photo shows my kid had a puddle of an accident in his bed, urine did not leak thru and the urine was sitting there for at least 2 hours. Easy to clean, I wipe with an all purpose cleaner and warm water. Dries fast! I recommend!
Review: Final verdict: Thin, fragile, useless. Avoid at all costs. - The DMI Twin XL Zip Mattress Cover is shockingly cheap in every possible way. When I say thin, I mean borderline imaginary. This thing feels like it’s made out of the same material as a grocery store produce bag, maybe thinner. Calling it a “mattress cover” is generous. It offers zero protection, zero durability, and zero confidence that it will survive normal human existence. A child rolling over in bed was enough to rip it open. Not jumping. Not roughhousing. Rolling over. If your mattress experiences gravity, this cover is already in danger. The zipper is flimsy, the fabric stretches like wet paper, and once it tears, that’s it, it doesn’t just rip, it gives up on life. There is no waterproofing worth mentioning, no thickness, no reinforcement. It feels like a disposable item that someone accidentally decided to sell as a permanent product. If you’re trying to protect a mattress from spills, accidents, pets, kids, or literally anything more aggressive than a gentle breeze, do not buy this. It’s super cheap in price and somehow even cheaper in quality. You’d be better off wrapping your mattress in a fitted sheet and hoping for the best. This product should not exist, and the fact that it’s marketed for actual use is almost insulting. Final verdict: Thin, fragile, useless. Avoid at all costs.
