Questions about beds and mattresses answered & stories told.

No, twin and double mattresses are not the same thing. They are different in terms of size.

A twin mattress, also known as a single mattress, is the smallest standard mattress size available. It is typically designed for a single person and measures approximately 38 inches wide and 75 inches long (38" x 75"). There is also a variation called a twin XL, which has the same width but is longer, measuring around 38 inches wide and 80 inches long (38" x 80").

On the other hand, a double mattress, also known as a full mattress, is larger than a twin mattress. It is designed to comfortably accommodate one adult or a couple. The dimensions of a double mattress are approximately 53 inches wide and 75 inches long (53" x 75"). Similar to the twin size, there is also a double XL or full XL size available, which has the same width but is longer, measuring around 53 inches wide and 80 inches long (53" x 80").

So, while both twin and double mattresses are popular choices for single sleepers, they differ in size, with the double mattress being wider and providing more space for sleeping.
