Yes, in fact I would recommend it.
Correct answer: No, they are typically designed not to use a box spring.
A box spring is meant to elevate and support a mattress on a basic bedframe. If you have a platform bed, you don't need the support, and the added height would be a matter of your preference of aesthetics and ergonomics.
A full size platform bed could be a good investment. You will not, however, receive in return what you've paid for it, but you will be able to use if for many years. The price is lower since there's not a box spring. It is easier to move for this reason. It will also make an excellent guest bed.
If you have a set of box springs you should replace them when you get a new mattress as they wear out. If you have a foundation (rigid platform) and it is in good repair and sits flat you will get just as long a wear out of your new mattress as you will with a new foundation. It will probably void your warranty, but if you bu a decent mattress and take care of it you most likely will have no issues. You should not use a box spring with a bed designed for a foundation as it will wear prematurely. over 90% of the beds made today have foundations. Also a bed designed for a box spring should not have a foundation used on it. The innerspring on a platform and box spring bed are designed differently.
When you are buying a bed there are two pieces. One is the box spring and the other mattress itself. You can use the mattress by itself but to be more comfortable you should get both pieces.
It depends on your bed frame. Some frames are basically just rails down the side and possibly a couple of slats running across; these need a rigid support like a box spring. However, if the frame is capable of supporting a mattress by itself, you don't really need the box spring.
Yes. The mattress will sag between the slats. An unsupported mattress will not only lose its integrity, it can cause problems with your back, not to mention your sleep. Mattress warrantees may also be voided if not supported by a proper foundation. Many people purchase platform beds for their low profile. If a mattress and foundation set makes the bed higher then desired, there are low profile foundations available to put under the mattress. If any foundation rises the mattress higher then desired, a plywood deck may be used. Be sure to check your manufacturer warrantee on the use of decking. If all the above fails, there are mattresses available that have a frame build into the bottom of the mattress. These mattresses are widely used for bunk beds in twin and full sizes. Other than low profile, the other reason people buy platform beds is because it saves money on box spring. before saying no, i would suggest you give it a try, see if there is a sagging problem or if you will have trouble sleeping at night. If none of that happens, then a box spring may not be needed. Of course, if you have the budget and don't mind spending another $300, then buying a matching box spring is always a good idea. I have found this blog about platform bed is useful, maybe you should keep track of it, it has a post just discussing the issue about box spring on a platform bed.
They will not. A queen size bed is 60" x 80" and a twin size is 39" x 75" and an XL twin would be 39" x 80". Two XL twin box springs are what you would use for a king size bed.
Japanese bed frames are now available. They are available in King and Queen sizes. With the special design of Japanese bed frames there is now no need to use a box spring if you have one.

You can put a mattress on the floor and it will be ok to sleep on. Box springs are a unit that allows you to use the matress on a bed. The springs sit on the edges of the bed frame and keep the mattress from falling on the floor. If your bed frame has slats that go across from one side to the other, you can just use a mattress. It won't be as comfortable.
