No, a twin box spring is not large enough. It would take 2 extra long twin box springs (80 inches in length, as opposed to a regular twin's length of 75 inches), as a kings size mattress is 80 inches long and 76 inches wide (which is twice the width of two twin box springs). Keep in mind that 76x80 is the measurements of an eastern king size mattress, as a western or "California" king mattress measures 72x84 inches.
Yes. Extra long only. If they are not extra long they will fit. But the mattress will be to big for the boxsprings.
Yes you can cut a king mattress pad to fit a twin, just make sure to measure carefully.
No. Two twin size mattress will fit a king size bed frame.
No. Two twin size mattress will fit a king size bed frame.
It is used when you can not fit a standard queen box spring into the door of a room, or upstairs in an elevator etc.
no
No, they will be too short. A Cal King sheet would fit on both twin beds, if they are pushed together.
Yes, they should.
Duvet covers come in king, queen/full, twin. They will fit comfortors which are the same size.
Your question is missing one key element: a queen what?If you are trying to place a queen mattress on a twin-sized box spring, the answer is a definite no.If you'd like to use a queen sized headboard with a twin box spring, the answer is "probably", with some modifications. Depending upon the construction of the headboard, and whether or not it can rely upon a nearby wall for support, you can use a headboard you love with an existing bed, even if the sizes aren't exactly the same. You can remove non-decorative legs from the headboard and hang it on the wall at the head of the bed, like a piece of art. You can attach the headboard as intended to the bed frame and disguise the exposed legs with an extension of the bed skirt, or paint them to match the wall. You can use the headboard along the long side of the twin bed, as the back to a daybed arrangement.If, however, you are considering using a twin-sized box spring on a queen-sized bed frame, you will have to discover whether or not the frame is made to be adjustable, and, if not, you'll need to install some sort of supportive decking material into the frame, for the box spring to set upon. This arrangement will leave dangerous exposed corners sticking out beyond the mattress, which have to be dealt with, perhaps with a padded cover all around the frame. My advice would be to skip all this retrofit effort, and purchase a new bed frame to fit your box spring. They are generally less than $100.
