Video transcript

No, a full-size and twin mattress do not make a king. A king-size mattress measures 76 inches wide by 80 inches long. However, placing a full-size mattress (54 inches wide) alongside a twin mattress (38 inches wide) would create a combined width of 92 inches, which is too large for standard king-size bedding.
