“Fits my Ezebaby bedside bassinet (19 x 32) perfectly. They held up well in the washer and drier before I put one of the covers on. They are very soft and not too thin, I think they add a little extra softness/padding to the thin mattress the bassinet comes with. It’s not noisy and I really like that it’s OEKO-TEX certified/ hypoallergenic. Planning to buy some of their bassinet sheets too!”

“We have several of these sheets, and they are wonderful! They’ve been through probably 100 washes and they are still good as new. They don’t seem to stain either! They protect his bassinet mattress perfectly- nothing has ever seeped through. Highly recommend this protector!”

“Life savers for late night leaks. Nothing got through these, all I had to do was rip one off and put the second one on with a new sheet and put baby back in there. Love that it comes as a set of two. Comfortable, easy fit, great product!”

Frequently asked

What’s the difference between ‘Waterproof’ and ‘Waterresistant’? +

Water-resistant mattress protectors typically do not have a plastic layer and usually can’t handle major leaks or spills. Baby gear needs proper waterproof mattress protectors to get through those first couple of years.

Are mattress protectors safe for babies? +

As long as mattress protectors are fitted and made of hypoallergenic, natural materials, they are essential for small babies.

How often should I change a mattress protector? +

A mattress protector should be changed as soon as it is soiled. This can happen often, so always have an extra one at hand. Check the protector for any cracks or tears every 6 months.

How to use a mattress protector? +

Use a mattress protector under your fitted sheets. Make sure it fits tightly and can’t be easily removed as the baby becomes more mobile.

Can I use a crib mattress protector for a playard or a bassinet? +

No. Size is very important for baby bedding. Only use correctly sized mattress protectors for the individual baby item.
