Full Mattresses

What Is a Full Size Mattress?

A full size mattress (also known as a double mattress) measures 54 inches wide by 75 inches long. It's 15 inches wider than a twin but 6 inches narrower and 5 inches shorter than a queen, making it an excellent middle-ground option for single adults, teens transitioning out of a twin bed, and guest bedrooms where space is limited. At LA Mattress Stores, we carry full size mattresses in every type — memory foam, hybrid, innerspring, latex, and organic — from trusted brands like Tempur-Pedic, Stearns & Foster, Sealy, and Diamond Mattress.

While queen and king sizes get most of the attention, the full size mattress remains incredibly popular — with over 110,000 monthly searches for "full size mattress." It's the smart choice when you want more sleeping space than a twin without the footprint of a queen, especially in LA apartments and smaller bedrooms where every square foot matters.

Benefits of a Full Size Mattress

A full size bed mattress offers unique advantages for the right sleeper:

• Space-Efficient: A full mattress needs only a 9' × 10' room to fit comfortably with nightstands and walking space. That's significantly smaller than the 10' × 10' minimum for a queen, making it ideal for LA apartments, studio layouts, and secondary bedrooms.
• Generous for Solo Sleepers: At 54 inches wide, a full mattress gives a single sleeper ample room to stretch out and change positions freely through the night. It's a significant upgrade from a twin's 38-inch width.
• Great for Teens and Young Adults: Full mattresses are the most popular upgrade for teenagers outgrowing their twin beds. They provide adult-level comfort without requiring a bedroom redesign.
• Budget-Friendly: Full size mattresses cost 10–20% less than queen equivalents and require less expensive bedding. It's a practical way to get premium mattress quality at a lower price point.
• Perfect Guest Bed: A full mattress in a guest room accommodates virtually any single visitor comfortably and can sleep two in a pinch, all without dominating a smaller guest room.

How to Choose the Right Full Mattress

If you're looking for a full mattress near me in Los Angeles, consider these factors to find the best match:

• Who's Sleeping on It: For a single adult, virtually any mattress type works well in full size. For a teenager, focus on durability and medium firmness that supports a growing body. For a guest room, a medium-feel hybrid offers versatile comfort for visitors of all preferences.
• Full vs. Full XL: A standard full is 75 inches long, while a full XL extends to 80 inches. Taller adults (over 5'10") should consider a full XL or queen for the extra 5 inches of leg room. We carry both sizes.
• Mattress Type: Memory foam full mattresses excel at pressure relief for solo sleepers. Hybrid full mattresses offer balanced support with cooling. Innerspring models provide a traditional bouncy feel. For eco-conscious shoppers, our organic full mattresses use certified natural materials.
• Height and Thickness: Full mattresses range from 8 to 15 inches thick. A 10–12 inch mattress is the sweet spot for most sleepers, providing adequate comfort layers without making the bed uncomfortably tall.

Full vs. Queen Mattress: Which Should You Choose?

The full vs. queen decision often comes down to room size and whether you share the bed. A queen mattress (60" × 80") offers 6 more inches of width and 5 more inches of length — meaningful upgrades for couples or taller sleepers. However, if you're a single sleeper in a room under 10' × 10', a full mattress provides plenty of space while leaving more room for furniture, a desk, or walking space. For couples, we generally recommend a queen as the minimum size. Browse our queen mattress collection if you're considering the upgrade.

Full vs. Twin Mattress

A twin mattress (38" × 75") is 16 inches narrower than a full — that's a substantial difference in sleeping space. If you're upgrading from a twin and your room can accommodate a full (9' × 10'), the extra width makes a dramatic improvement in sleep comfort. For children under 12 or very compact rooms, a twin is practical. For teens, adults, and guest rooms, a full size mattress is the better investment.

Full Size Mattress FAQ

What are the exact dimensions of a full mattress?

A standard full size mattress (also called a double mattress) measures 54 inches wide by 75 inches long (137 cm × 191 cm). A full XL measures 54" × 80". Thickness varies by model, typically 8–15 inches. Your bed frame should measure at least 56" × 77" to accommodate a standard full.

Can two people sleep on a full mattress?

While two adults can physically fit on a full mattress, each person only gets 27 inches of width — less than a twin bed. For regular co-sleeping, a queen or king mattress is strongly recommended. A full works for occasional sharing (guest visits, sleepovers) but isn't ideal for every-night couple sleeping.

Is a full mattress the same as a double mattress?

Yes, "full" and "double" are interchangeable terms for the same 54" × 75" mattress size. The term "double" originated when it was marketed as being double the width of a twin, though it's actually only 16 inches wider. "Full" is the more commonly used term today.

What bed frame do I need for a full mattress?

A full mattress works with any full-size bed frame, platform bed, or adjustable base. You don't need a box spring for modern full mattresses — a solid foundation or slat system works well. Our team can recommend the right foundation for your specific full mattress at any of our Los Angeles locations.
