Queen Split Head Medium Double/Full Size Mattresses

54” wide by 75” long

Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium

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.

Frequently Asked Questions About Double/Full Size Mattresses

Are double and full size mattresses the same thing?
Yes. “Double” and “full” refer to the same mattress size: 54” × 75” (137 cm × 191 cm). “Double” is the traditional Canadian and British term, while “full” is more common in American usage. Every double/full mattress at National Mattress fits standard double bed frames. Learn more about double vs. full sizing.
Can two adults sleep comfortably on a double/full mattress?
A double/full gives each partner about 27 inches of width — roughly the same as a crib mattress. It can work for couples in smaller rooms, but a Queen (60” × 80”) provides 6 more inches of width and 5 more inches of length for noticeably more comfort. Read our couples guide.
What firmness level is best for a double/full mattress?
It depends on your sleeping position. Back and stomach sleepers generally prefer firm to extra firm for proper spinal alignment. Side sleepers benefit from medium to plush for pressure relief at the shoulders and hips. Our mattress selector tool can match your sleep style to the right firmness.
What is the difference between a full and a queen mattress?
A full measures 54” × 75” while a queen measures 60” × 80”. That gives a queen 6 extra inches of width and 5 extra inches of length — a meaningful upgrade for taller sleepers (over 5’10”) or couples. A full fits better in rooms under 10’ × 12’. Compare full vs. queen in detail.
Do double/full mattresses come with free delivery in Canada?
Yes. National Mattress offers free express delivery across Canada on all mattress orders. Every double/full mattress also includes a 365-night sleep trial, price match guarantee (beat by 10% of the difference), and full manufacturer’s warranty coverage of 5–25 years.

National Mattress carries double/full models from 10 brands: Springwall, Serta, NM, Beautyrest, Sealy, Evergreen, Chirofoam, Stearns & Foster, Tempur-Pedic, and iComfort — with prices starting at $124.
