Learn More About LetMxiu Waterproof Crib Mattress Protector Sheet →LetMxiu makes crib and toddler mattresses built around firm support and safety certifications, since infant sleep surfaces need to stay firm rather than plush. The lineup spans a premium memory foam mattress with a hand-sewn no-seam fit and velvet surface, a firm dual-sided foam mattress that can be flipped every 2-3 months, and a lighter knitted-cotton mattress under 10lbs for easy one-handed changes. Two bundles pair a mattress with a 100% waterproof, noiseless protector sheet, and the protector sheet is also sold on its own for parents who already have a mattress. Every mattress meets 16 CFR 1633/1632/1241 federal flammability standards and uses non-toxic, hypoallergenic materials sized to fit standard cribs and toddler beds without gaps.
Crib and toddler mattresses, mattress + protector bundles, and a standalone protector sheet.
A standalone fitted protector sheet for parents who already have a crib mattress. Its balanced waterproof membrane blocks urine, milk and sweat while staying soft and silent, with a deep skirt and elastic band for a secure fit and reinforced threads for hundreds of wash cycles.
Every mattress is built firm rather than plush, since infant sleep surfaces need stable support, and meets 16 CFR 1633/1632/1241 federal flammability standards.
Surfaces are made from breathable, skin-friendly fabrics like velvet, brushed cotton or knitted cotton, without harsh chemicals or strong odors.
Hand-sewn or precision-edge construction fits standard crib and toddler bed dimensions tightly, so there is no unsafe gap along the sides or corners.
Dual-sided mattresses can be flipped every 2-3 months for even wear, and the waterproof protector sheets keep accidents from soaking into the mattress itself.
Excellent crib mattress! It fits perfectly in our crib, and the quality is great. The mattress is firm, comfortable, and provides good support for my baby. The cover is soft and breathable, and there was no strong odor after opening. Highly recommended for parents looking for a safe and affordable crib mattress.
The Letmxiu Premium Crib & Toddler Mattress has been one of the best investments we've made for our baby's sleep setup. The 100% knitted fabric surface is incredibly soft to the touch, and you can tell it was designed with a baby's comfort and delicate skin in mind. The hypoallergenic materials are a huge plus for us.
Wow super impressed by this mattress. Feels like a great quality adult mattress. Super soft cotton feel and comfortable. Quiet when moving around. Perfect. Baby loved it first try right out of the box.
The mattress is absolutely amazing! The 100% knitted fabric with the premium fleece surface is so soft and cozy. The mattress is firm enough to be safe for baby while still giving a plush, comfy feel. Easy to clean and high-quality — exactly what I wanted for her nursery.
I've been using this crib mattress for a few weeks now, and I'm honestly very happy with the quality and comfort. It fit perfectly inside our standard crib with no unsafe gaps around the edges. One of my favorite things is the waterproof cover — cleanup was super easy with just a quick wipe down.
Product is very nice fabric, feels wonderful and 2 inch memory foam is identified with a firm/plush yet stable support. Would like to have a removable, machine-washable waterproof protector included with the mattress, but that is a small ask.
I'm genuinely impressed with the crib and toddler mattress. The quality stood out the moment I unboxed it. The 100% knitted fabric and premium fleece surface give it a soft, cozy feel that seems both breathable and comfortable for little ones.
We love these mattresses for our girls' toddler beds! They are such an affordable option and are soft yet slightly firm enough for our little ones. The mattress comes rolled up tightly in a vacuum seal. Once cut open it rolls out fully in less than a minute.
