Frequently asked questions
What is a long full mattress?
A long full mattress is 54 inches wide by 80 inches long, 5 inches longer than standard full (75 inches). It's designed for taller sleepers who need extra legroom without upgrading to a queen's width.
Who should consider a long full mattress?
Ideal for taller individuals (over 5'10") who sleep alone or share with a small child. It fits standard full-size frames but requires longer sheets. Suitable for guest rooms or small apartments where a queen is too wide.
How does a long full compare to a queen?
A long full shares the same length (80 inches) as a queen but is 6 inches narrower (54 vs 60 inches). It provides similar legroom for taller sleepers but less space for couples.
What certifications should I look for?
Key certifications include CertiPUR-US (foam safety), OEKO-TEX Standard 100 (no harmful substances), and GOTS (organic materials). They ensure lower VOCs and no heavy metals.
How long do long full mattresses typically last?
Average lifespan is 7-10 years with proper care. Materials matter: hybrid and latex models often outlast all-foam. Regular rotation and a quality foundation extend longevity.
