Full MattressesFull MattressesFull Mattresses

A standard full-size mattress—also known as a double—is 53 inches wide and 75 inches long. With these dimensions, it’s somewhere between a luxurious twin and a space-conscious queen bed.

With its balanced yet compact size, many people consider a full bed a “starter size,” perfect for young adults, guest rooms, and minimalist couples. For a sleeper looking at a full bed mattress, you’ll want to ensure your bedroom is at least 9 x 9.5 feet to comfortably accommodate the bed.

A full-size mattress can cost anywhere from 400 to 1,900 CAD, depending on the quality of the mattress type and special features—cooling technology, structural support, pressure relief, multiple layers, and so on. Before purchasing a new mattress, consider your needs and the firmness level you prefer. Determining whether you want a softer mattress or firmer mattress can help you initially narrow down your search. For a full-size memory foam mattress, the price usually increases to around 750 CAD.

The best full-size mattress will accommodate both your budget and heighten your comfort level, providing the best possible sleep experience for its price point. Casper’s Element full-size memory foam mattress comes in at a bargain of only 545 CAD.

While snug, a full-size bed can certainly fit two people, especially if your go-to sleeping position is cuddled up together.

However, many couples prefer more space to rest easy. A full bed’s width only grants each partner a little over two feet of personal space. Once you factor in potential children or pets, a full bed becomes crowded quickly. For the best bed size for couples or for a sleeper who needs more space to stay cool and comfortable, a queen size mattress or king size bed will better suit your lifestyle.

The choice between a queen and full bed depends on your home, lifestyle, and sleep needs.

At 53 inches wide and 75 inches long, a full bed is best for solo sleepers, but this compact bed frame size could match other living situations—smaller shared bedrooms or cuddling couples, for example. Most couples prefer more personal space for a good night’s rest, whether that means upgrading to a queen or even a king. Similarly, anyone over six feet tall should opt for a bigger bed to maximize their comfort level, as the 75-inch length of a full bed likely isn’t enough.

A queen bed sits at 60 inches wide and 80 inches long, adding 7 inches in width and 5 inches in height to a full bed’s dimensions. For couples, taller individuals, or restless sleepers who move around at night, that bed frame's extra wiggle room often makes a big difference in comfort. Similarly, a queen bed’s extra space better fits homes with kids or pets that might crawl into bed with you. As long as your bedroom is at least 10 x 10 feet, it can easily accommodate a queen bed and a larger mattress size.
