Frequently asked questions
What is a full XL mattress protector?
A full XL mattress protector is designed for full extra long mattresses, commonly used in dorm rooms and some RVs. It measures approximately 54 by 80 inches, offering full coverage with a fitted sheet style design.
Do mattress protectors affect mattress feel?
Some protectors can alter the feel, especially if they are thick or have a plastic backing. Look for thin, breathable options like bamboo or cotton terry to minimize changes. Waterproof layers vary in noise and pliability.
How often should I replace a mattress protector?
Most protectors last 2-5 years depending on quality and care. Wash them every 1-2 months to maintain hygiene. Replace if the waterproof layer is compromised or if staining occurs.
Are all mattress protectors waterproof?
Not all are waterproof. Some are water-resistant or only act as a dust mite barrier. Check the product description for waterproof claims. Most protectors in our roundup are designed to be waterproof with a membrane.
Can I use a full XL protector on a regular full mattress?
No, a full XL protector is longer than a standard full (74 inches). Using it on a regular full will leave excess fabric, causing loose fit and potential bunching.
The verdict
For most owners, the SafeRest Full Extra Long Mattress Protector offers the best balance of protection and comfort. For cooling, choose the PlushDeluxe Bamboo. For tight budgets, the Linenspa is a solid performer.
