Frequently asked questions
What size is a long single mattress protector?
A long single mattress protector typically measures 38 inches wide by 80 inches long. This size is common for single beds in extended-length frames, often used in taller individuals or specific bed designs.
Are long single mattress protectors waterproof?
Many long single mattress protectors offer waterproof protection, usually through a TPU or vinyl backing. Some budget options may use thinner plastic, while premium models use breathable membranes that block liquid but allow air flow.
How do I wash a long single mattress protector?
Most mattress protectors are machine washable on a gentle cycle with cold or warm water. Avoid bleach and fabric softener, and tumble dry on low heat. Always check the care label for specific instructions.
Do mattress protectors affect comfort?
A high-quality protector with a cotton or knit top minimally affects comfort. Thin vinyl protectors may crinkle or retain heat, while premium terry or organic cotton options offer breathability and a soft feel that largely preserves mattress comfort.
What certifications should I look for?
Key certifications include OEKO-TEX Standard 100 (textile safety), CertiPUR-US (foam-free and non-toxic), GOTS (organic fibers), and GREENGUARD Gold (low chemical emissions). These ensure the protector is free from harmful substances and safe for allergy sufferers.
