Frequently asked questions

Will a 3 inch twin XL topper fit my dorm bed?

Yes, twin XL is standard for dorm beds (80 inches long). The topper will fit perfectly, though check mattress thickness to avoid too high a profile.

All our picks are CertiPUR-US or OEKO-TEX certified, meaning they meet strict standards for emissions and materials. However, some may have initial off-gassing.

Latex toppers often last 10+ years, while memory foam averages 3-5 years. Durability depends on usage and quality.
