NM® MLILY® Double/Full Size Mattresses
54” wide by 75” long
MLILY® is a global sleep brand known for memory-foam comfort and modern hybrid design, made in the USA. From the cooling PowerCool and the pocket-coil Midnight and ChiroPro hybrids to the all-foam WellFlex and the officially licensed Manchester United collection, MLILY pairs AeroFusion™ foams with individually pocketed coils for supportive, motion-isolating sleep. Backed by warranties up to 10 years and free next-day delivery in Toronto.
A double mattress (also called a full mattress) measures 54" wide by 75" long — the same length as a twin but 15 inches wider.
It's the most popular choice for single adults who want more room than a twin, couples in smaller bedrooms, teenagers moving up from a kid-size bed, and guest rooms where space is limited.
Every double mattress at National Mattress ships free across Canada with a 365-night sleep trial, price match guarantee, and 5–25 year manufacturer's warranty.

How to Choose the Right Double/Full Size Mattress
A double/full mattress measures 54” × 75” (137 cm × 191 cm), providing 15 inches more width than a Twin while fitting bedrooms where a Queen would be too large. This size works well for single adults who want extra room to move, teenagers transitioning from a smaller bed, and guest rooms with moderate floor space. For couples, a double can work but offers only 27 inches per person, so consider a Queen if you share the bed regularly.
The construction type has the biggest impact on how your mattress feels. Eurotop and pillowtop models add a sewn-in cushion layer for plush surface comfort while keeping the supportive core intact. Innerspring and traditional tight-top mattresses offer firmer, more responsive support, ideal for back and stomach sleepers. Hybrids combine pocketed coils with foam layers for balanced contouring and airflow, while memory foam and latex models provide deep pressure relief with minimal motion transfer. Over 88% of the double/full mattresses at National Mattress are pocket coil or hybrid builds, and nearly 90% are compatible with adjustable bed bases.
