Full Size Mattresses in Los Angeles

Yes. Full and double are two names for the exact same mattress size: 54 inches wide by 75 inches long. The term "double" dates back to when this size was considered large enough for two people. Today, "full" is the more commonly used term in retail, but you will see both names used interchangeably by manufacturers, retailers, and consumers. Any full bed frame fits a double mattress and vice versa.

A full (54"×75") is 6 inches narrower and 5 inches shorter than a queen (60"×80"). For a single adult in a smaller bedroom or studio apartment, a full is the smarter choice — it leaves more floor space without sacrificing personal sleep comfort. For two adults sharing the bed, a queen is the minimum we recommend. The 6-inch width difference matters significantly when sleeping with a partner. If your room is 10'×10' or larger and you'll be sharing the bed, go queen. If you're sleeping solo in a tighter space, full is the practical choice.

For adults sleeping solo, the best full mattress depends on sleep position and preference. Side sleepers benefit from a plush to medium-soft hybrid or memory foam that relieves hip and shoulder pressure. Back sleepers do best with medium to medium-firm for lumbar support. Stomach sleepers need firm to extra-firm. For general use, a medium-firmness hybrid in full from or Helix offers the best balance of support and comfort. We carry 171 full mattresses across 8+ brands — our specialists can narrow it down to 2 or 3 to try in person.

At 54"×75", a full mattress requires a minimum room size of approximately 9'×10'. That gives you a few inches of clearance on each side. For comfortable clearance — room to walk on both sides and space for nightstands — a 10'×12' room is recommended. If your room is smaller than 9'×10', consider a twin or twin XL. If your room is 10'×12' or larger and you're sleeping solo or with an occasional guest, a full fits with ease. Measure your room before ordering and leave at least 24" clearance on one accessible side.

At LA Mattress Store, full size mattresses range from $299 for a quality foam or innerspring to $1,699+ for premium models from Tempur-Pedic or Stearns & Foster. The value range for most shoppers is $399–$899, where you'll find solid hybrid and foam options from and Helix with good durability and comfort. All full size mattresses include free delivery.

Technically yes, but not comfortably for most couples. At 54" wide, each person has about 27 inches — roughly the width of a crib mattress each. Most adult couples find this too tight for regular nightly use. If you occasionally share the bed with a partner, a full can work. If you share nightly, a queen (60" wide) is the recommended minimum. For couples who value personal space during sleep, a king is worth considering.

A full mattress (54"×75") is 16 inches wider than a twin (38"×75"). Both are the same length at 75 inches. The 16-inch width difference is significant — a full offers noticeably more sleep surface for a single adult who moves during sleep or needs space. Twins are well-suited for children's bedrooms, bunk beds, and tight spaces. Full is the natural step up for teens transitioning from a twin, and for single adults who want more room without the footprint of a queen.
