Full Size Mattresses

Full Size Mattress Dimensions

A standard full size mattress measures 54 inches wide by 75 inches long, or about 137 by 191 centimeters. That's 16 inches wider than a twin, and 6 inches narrower and 5 inches shorter than a queen. Mattress height varies by model, from about 6 inches for a bunk bed or trundle mattress to 15 inches or more for a plush euro top hybrid, so check the profile when you're matching a bed frame or fitted sheets.

Full vs. Twin vs. Queen: Which Size Is Right for You?

Choose a full size mattress when a twin feels cramped but a queen would crowd the room. At 54 inches wide, a full gives one adult plenty of space to roll over and stretch out, and it fits comfortably in a bedroom of about 10 by 10 feet with room left for a nightstand and dresser. It's a popular upgrade for kids moving out of a twin, a smart pick for teens and college students, and an easy way to make a guest room feel welcoming. Two adults can share a full in a pinch, but each person gets just 27 inches of width, about the width of a crib mattress. Most couples are happier on a queen mattress, while kids' rooms and bunk beds often call for a twin mattress.

Memory Foam, Hybrid or Innerspring?

A full size memory foam mattress contours to your body, relieves pressure at the shoulders and hips, and absorbs motion. Many of ours add cooling gel or copper-infused foam to help you sleep cooler, which is welcome during a Texas summer. A full size hybrid mattress pairs pocketed coils with foam comfort layers for a bouncier feel, better airflow and sturdier edges, which makes it a great all-around choice. A classic innerspring mattress delivers a familiar, supportive feel at an affordable price. Shop by type with our memory foam mattresses, hybrid mattresses and innerspring mattresses, or compare them side by side in our memory foam vs. hybrid vs. innerspring guide.

Find the Right Firmness for How You Sleep

Side sleepers usually feel best on a plush or medium mattress that cushions the shoulders and hips. Back sleepers tend to prefer medium to medium-firm support that keeps the spine aligned, and stomach sleepers often need a firmer surface that keeps the hips from sinking. Our full mattresses range from ultra plush euro tops to extra firm models, so you can browse plush mattresses, medium firm mattresses or firm mattresses, or read our guides to the best mattress for side sleepers and back sleepers.

Full Mattress Sets, Foundations and Bed Frames

Many shoppers buy a full size mattress and box spring together as a set. A traditional box spring adds height and a little give, while a modern mattress foundation provides the firm, even support that most foam and hybrid mattresses need. If your full size bed frame has a platform or closely spaced slats, you may not need either. Want to raise your head or feet? Many foam and hybrid full mattresses also work on an adjustable base. Whatever you choose, check the mattress warranty for its support requirements, and finish your setup with a waterproof mattress protector.

Full Mattresses for Bunk Beds and Kids' Rooms

Shopping for a full-over-full or twin-over-full bunk bed? Choose a mattress that stays within the bed's maximum recommended thickness, often 6 to 8 inches, so the guardrails stay high enough to keep sleepers safe. Our low-profile foam mattresses with built-in bunkie boards are made for bunk beds and trundles, and a separate bunkie board adds solid support without adding height.

Full Size Mattress FAQs

What are the dimensions of a full size mattress?

A standard full size mattress measures 54 inches wide by 75 inches long, or about 137 by 191 centimeters. Mattress height varies by model, typically from about 6 inches for bunk bed mattresses to 15 inches or more for plush hybrids and euro tops.

Is a full mattress the same as a double mattress?

Yes. Full and double are two names for the same mattress size, 54 inches wide by 75 inches long. Full size sheets, bed frames and foundations all fit a double bed.

What is the difference between a full and a queen mattress?

A queen mattress measures 60 by 80 inches, so it is 6 inches wider and 5 inches longer than a full at 54 by 75 inches. A full fits better in smaller bedrooms and guest rooms, while a queen gives couples and taller sleepers more space.

Is a full size mattress big enough for two people?

A full can sleep two adults, but each person gets only about 27 inches of width. It works for guests or occasional use, but most couples sleep better on a queen or king. A full is ideal for one adult, a teen or a growing child.

What is a full XL mattress?

A full XL mattress measures 54 by 80 inches, the same width as a standard full but 5 inches longer for taller sleepers. It is less common than a standard full and needs full XL sheets and a frame made for the longer length.

Can a full mattress fit on a queen bed frame?

Not well. A full mattress is 6 inches narrower and 5 inches shorter than a queen frame, which leaves gaps and lets the mattress shift. For the best support and fit, pair a full size mattress with a full size bed frame or foundation.

Do I need a box spring for a full size mattress?

It depends on your bed. Platform beds and frames with closely spaced slats usually do not need a box spring, while traditional metal frames need a box spring or foundation for support. Check the mattress warranty, since many foam and hybrid mattresses require solid, even support.

How much does a full size mattress cost?

At Bel Furniture, full size mattresses start under $200 for basic foam and innerspring models. Most quality memory foam and hybrid full mattresses cost between about $300 and $1,000, and luxury hybrids go higher. Ask about special financing to spread out the cost.
