Every mattress should work on a platform bed. Box springs are not necessary like they are with normal bed frames. If the bed height is comfortable for you and the mattress is properly supported, you don't need a box spring (just check the mattress warranty). Platform beds are sturdy and give enough support from either a flat sheet of wood or slats.
While nearly every mattress available can be paired with a platform bed, there are some things to consider. For instance, traditional innerspring beds typically do better with a box spring, and many warranties require one. While you can place a box spring on a platform bed in some cases, it will raise the height considerably and may not work with every platform bed.
Memory foam mattresses are a great option for platform beds, but you need to make sure that the platform bed has a stable support system. Memory foam mattress warranties will often require the platform to be solid. It's not recommended to place a memory foam mattress directly on a platform bed if the slats are more than 6 inches apart. If that is the case, you'll want to pair it with some type of box spring or bunkie board to ensure proper support. If you think your mattress needs added support, you should add a foundation to it for insurance.
Hybrid mattresses will also work well with a platform bed, as will latex beds. The most important consideration is making sure your mattress is well-supported. As long as you have the right support, the platform bed will not cause issues like back pain. Also, make sure to follow your warranty or it may be voided.
Although you can use a box spring on a platform bed, you probably don't need one. The decision comes down to whether you feel you need extra support and if you like the additional height. In most cases, you can use any box spring you wish on a platform bed. If you already have a box spring that you plan to use with a new platform bed, you should measure it to be sure it will fit properly.
Your bed height may feel too tall if you combine a platform bed with a standard box spring. If you do need to buy a foundation, there are options that won't add a lot of height. Low profile foundations or bunkie boards will support the mattress as well as a standard box spring would.
A mattress and platform bed combo will usually sit lower than a traditional bed, box spring, and mattress set. So, for people who actually prefer a higher bed, you could use a box spring to achieve that. This is one of the only reasons to use a box spring. Platform beds use slates or a deck to provide the same flat, supportive surface as a foundation. Using the two together won't improve the comfort or longevity of the mattress. The key point is making sure your mattress is supported.
