If you want to protect your mattress, this makes it simple.
This is the Cosyaby waterproof mattress topper cover set.
It comes with three pieces, so you can easily change and rotate them.

Love love love this set I purchased for my son! It fits over his mattress perfectly and has a nice cozy feel to it; quality material for the price. Looking to get a second set in blue. I’m definitely pleased with my purchase!

Bought two sets- BOTH of the underlying plastic lining RIPPED ALL THE WAY ACROSS w one 3 minute gentle washing cycle. I want my money back on this scam.

Ok, idk why i thought this would be a zipped cover? But its NOT its fitted! I bought this to place over our 12 y.o mattess & bed topper. To my satisfaction. It fit both as pictured! His matress is a twn xl! Hopefully it won’t slip off? Will update to see if the functionality is perfect over all!

This is the fourth I have bought, they are awesome and they're very good looking on the bed. They will match the sheets that you use daily.

Features:
·TPU Film: Opening the package, you can flip the back of the bed cover and see a layer of white TPU waterproof film. Elastic and breathable, with micro-pores (≈0.1-1μm) for evaporation and blocking liquid penetration.
·Wash-Resistant: Anti-aging, tear-resistant, and undamaged in machine washing.
·Breathable Fabric: Hydrophilic fiber structure absorbs spills quickly, blocks dust and dander.
·Sizes:Twin Size: Fitted Sheet: 39"x75", 1 x Pillowcase: 20"x26".Full Size: Fitted Sheet: 54"x75", 2 x Pillowcase: 20"x26".Queen Size: Fitted Sheet: 60"x80", 2 x Pillowcase: 20"x26".King Size: Fitted Sheet: 78"x80", 2 x Pillowcase: 20"x36".
·Elastic Bands: Fit tightly, avoiding shifting.
·TPU Film: Offers slight elasticity to prevent cracking when the mattress deforms.
Washing Precautions:
·Do not use agitator washing machines — may damage the waterproof membrane.
·Do not iron — high temperature will damage the waterproof coating structure.
·Do not use bleach, chlorine-containing cleaners, strong acid or alkali detergents — avoid coating corrosion.
·Do not wash or dry at high temperature — high heat causes waterproof coating aging, cracking, and failure.
·Wash in cold water (below 30℃) on "gentle mode" or by hand.
·For stains: gently brush with a soft brush, do not scrub vigorously.
·Use neutral detergent only.
·Air-dry naturally in a cool, ventilated place — avoid direct sunlight exposure.
Ideal for busy families, this cover prevents seepage through gaps. Keep your bedroom tidy and dry effortlessly!
