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.
A full sized mattress is 54" x 75". If you want an edge around the mattress (for example, if you are making a platform style bed) then figure out the edge you want and calculate accordingly. I always use a piece cut exactly to the mattress measurements, and that works fine for me.
Full mattresses are the size between a twin and a queen size mattress. A full mattress measures 54 by 75 inches.
Many furniture stores sell full platform beds in both their brick and mortar stores and their online sites. A few good retailers to look at include: Sears, IKEA, Walmart, and Ashley Furniture HomeStore.
Queen sized mattress are 6 inches wider and 5 inches longer than a full sized mattress.
The price range for Sealy mattress sets depend on whether you buy from a wholesaler who sells older stock vs. retail such as department stores. Comparison shopping is most useful in finding prices.
