- Does it actually keep liquids off the mattress?
- Yes. The waterproof backing is the point of this cover, so spills and accidents stay on the surface and can be wiped or washed off.
- Will it fit a standard twin mattress?
- It is sized for a twin at 75 inches long, which matches a standard twin mattress. Check your mattress depth, since deep-pocket fit is not specified.
- Is it comfortable to sleep on directly?
- It is a thin polyester protector, not a padded topper. Most people put a fitted sheet over it; the waterproof layer can feel warm or slightly crinkly.
- How do I wash it?
- Machine wash and tumble dry low is typical for polyester waterproof covers. Avoid high heat, which can damage the waterproof backing over time.
- Is $30.64 a good price?
- Walmart lists it at $30.64 as of November 7, 2026, and it is the only new price listed. With no other stores to compare, judge it against what you would pay for any basic twin waterproof cover.
- Where is the Allerease Maximum Protector Twin Size cheapest?
- At Walmart, for $30.64, as of our latest check.
