what is the standard size of daybeds
Daybeds and twin mattresses are one in the same, both being 39 inches wide and 75 inches long. Many daybeds are also trundle beds, and the terms are sometimes used interchangeably. A trundle bed is one that hides a second bed underneath the first. When the bed is needed, the trundle slides out from beneath the primary bed to provide another sleeping space. Trundles are available in standard twin size but must be no more than 8 inches high so they can fit under the other bed.
