Frequently asked questions
What is a cot mattress cover with zipper?
It’s a protective encasement that fully wraps around a cot mattress, sealing it from spills, dust mites, and allergens. The zipper allows easy removal for washing.
Are zippered covers waterproof?
Most are, using a waterproof membrane like polyurethane. Always check product specs, as some are only water-resistant. Certifications like CertiPUR-US can indicate quality.
How do I choose the right size?
Measure your mattress depth and width. Most covers fit standard 8-12 inch deep mattresses, but check product dimensions. A snug fit prevents shifting.
Can I use it with a mattress topper?
Yes, but ensure the cover is deep enough to accommodate both mattress and topper. Alternatively, place a fitted sheet over the topper and cover separately.
How often should I wash it?
Every 2-3 months or after spills. Machine wash on gentle cycle and tumble dry low. Avoid bleach or high heat to preserve waterproofing.
