The full-size mattress is perfect for:
If you’re shopping for versatility and value, the full-size bed is an excellent choice. For couples or taller individuals, however, upgrading to a queen might be the smarter long-term investment.
1. What are the dimensions of a full bed?
54 inches wide × 75 inches long.
2. Is a full bed the same as a double bed?

3. Can two adults sleep on a full bed?
Technically yes, but it may feel cramped especially for taller or broader individuals.
4. What’s the ideal room size for a full bed?
At least 10' × 10' for balanced furniture placement.
5. How does a full compare to a queen?
A queen is 6 inches wider and 5 inches longer better for couples.
6. Is full bedding cheaper than queen?
Yes, sheets, frames, and mattresses are typically more affordable in full size.
7. Do full beds come in different firmness levels?
Yes plush, medium, and firm options are available at LA Mattress Store.
8. Are full beds good for growing teens?
Absolutely they offer more space than a twin while staying budget-friendly.
9. Does LA Mattress Store deliver full mattresses?
Yes delivery, setup, and old mattress removal are all included.
10. Should I choose a full or queen?
If you’re a solo sleeper or need to save space, a full is ideal. For couples, a queen is usually better.
Full mattress dimensions: 54" × 75" — 4 feet 6 inches wide by 6 feet 3 inches long (137 × 190.5 cm). Also called a "Double" in some regions; the names refer to the same mattress size. It's 16" wider than a Twin and the same length, so it gives a solo sleeper real elbow room without the room footprint of a Queen.
Bed full size dimensions in feet: 4.5 feet × 6.25 feet. Plan for at least 9 × 10 feet of bedroom — the bed itself takes about 28 square feet, and you need walk-around space on three sides to keep the room functional.

A full (also called a double) mattress is 54" × 75" — about 4 ft 6 in × 6 ft 3 in, or 137 × 190.5 cm.
Yes. "Full" and "double" are two names for the identical 54" × 75" mattress; the terms are interchangeable.
A full gives two sleepers about 27" of width each — fine for smaller couples or a solo sleeper who likes room, but most couples prefer a queen (60" × 80") for more shoulder space.
A 9 × 10 ft bedroom is the realistic minimum for a full once you allow walk-around space on two or three sides.
