Q: does the cover make noise like when u are tossing and turning on the cover sheet. Like u are on a plastic. Michael.

submitted by sojrnr6 - 1 year ago

  • A: Not for me it doesn’t

    submitted bymariyah - 1 year ago

  • A: Hello, due to the friction between materials, the presence of any layer of fabric on your mattress will not be 100% silent. However, our product is designed to minimize this effect while maximizing the protective benefits it offers – the prevention of spills & stains from coming into contact with your mattress. Thank you for your question.

Q: The package doesn’t state it’s OEKO-TEX certified anywhere and the products website doesn’t state this either. I reached out to the company and asked if it’s certified but got no response. How do we confirm this is OEKO-TEX certified?

submitted by Kathryn - 2 years ago

  • A: I asked this as well and have been waiting on an answer. I think its safe to assume it is not OEKO-TEX bc I could not find anything stating this either and they should take that down.

    submitted byLinda - 2 years ago

  • A: They likely use 1 material that is oeko-tex but the while product isn't certified

Q: Does this cover zip around the mattress or only cover the top like a fitted sheet?

submitted by toddler momma - 6 years ago

  • A: In video at 15 seconds you see someone using a zipper. I am confused now.

Q: If my mattress is only 10" thick, will the protector be loose because it is not stretched entirely.

submitted by JR - 13 days ago

  • A: Thank you for your question! A 10" mattress should still work well with the AllerEase Clean Boost Waterproof Fitted Mattress Protector. While the protector is designed to accommodate a range of mattress depths, it should not feel overly loose or baggy when properly fitted. The elastic skirt is intended to help keep it securely in place, even if your mattress is on the thinner side. If you have any other questions, please don’t hesitate to reach out—we’re happy to help!

Q: In the video at about 15 seconds there is shown someone zipping up the cover. I'm not clear if this item only covers 5 sides

submitted by RG - 10 months ago

  • A: Hello, this specific item is a fitted protector that covers 5 sides. The video is a commercial for the brand that shows off some of our products. Our other protectors vary to include fitted (5-sided coverage) and zippered (6-sided coverage). Thank you for your question.

    Says waterproof but it isn’t. Split something on the bed, went though sheets, the entire mattress cover into the bed. This isn’t waterproof by any means. Don’t recommend. Messed up a brand new bed.

    IS NOT WATERPROOF

    what a joke of a product. advertises itself as waterproof and yet our kid, even just leaking a small amount through her overnight pullup, has peed through these every time. NOT waterprood, false advertising. Dont buy this and target should drop this supplier ASAP.

    Thin, soft and a total mattress saver!

    Glad I waited for this because we immediately needed it. It’s soft so my child doesn’t feel like she has a pad underneath her sheets, but saved our new mattress. We got it for our full sized nectar kids mattress, plenty of room to stretch across without feeling too tight and popping off with movement.

    Not for bed wetters

    This cover leaks with bed wetting. Definitely not waterproof in a meaningful way. It might be fine if you’re trying to protect your mattress from dust and a small drink spill, but if you’re looking to keep a kid’s mattress clean, keep looking!

    Deceitful

    Not a full mattress protector as described, which should have had a zipper and been able to fully enclosed a mattress. Product goes on like a fitted sheet, leaving almost half a mattress completely unprotected. Also, not recommended for those with sensitive skin! I cannot recommend it even as a mere mattress topper cover.

    This is NOT waterproof, at all. I needed a waterproof mattress cover for my toddler. I bought this. She had an accident, and this cover let everything go straight through to our new mattress. This is false advertising.

    Great mattress protector!

    We needed a waterproof mattress for “just in case” spills/pets/kids/etc and this has worked out so well. It fits perfectly and does what it says. It’s easily washable and protects the mattress much more than with just a fitted sheet.
