We often tend to confuse between full beds and double beds. However, these are interchangeable terms. double bed and a full-size mattress are both the same and measure 54 inches wide and 75 inches long.  The irony is that double beds can’t hold two people comfortably. This is why manufacturers have popularized the term “full mattress” since the 1870s. Before introducing larger beds like king and queen, full beds were quite popular among couples.  Even though a double bed or a full-size mattress can accommodate two sleepers, the space doesn’t allow them to spread out and sleep comfortably. This blog will walk you through everything you need to know to tackle the double vs full bed debate.

What is a double bed?

A double bed measures 54 inches by 75 inches and was the perfect and popular choice among couples right before the world was introduced to the queen and king-size beds. 

Double beds were a popular product back in the early to late 90s. Double beds can equip two adult sleepers with adequate room but not enough comfort. Double beds have become popular in western countries due to better space utilization. 

With our detailed comparison and explanation, you will get your job done easily with the decision on the mattress.

What is a full-size mattress?

A full-size mattress also offers the same space as it has the same dimension scale as a double bed. If your room has a 10 X 12 ft dimension, a full bed mattress can be a comfortable and good product. This size leaves you with around 2 to 3 ft of extra space, which can be utilized for other purposes.
