Does my mattress require a box spring?
No, a box spring is not required if your current setup provides enough even support. You do not need to replace your current box spring if it is still in great shape.
The mattress needs to be supported at all times, so platform frames, slatted frames, bunky boards, and even adjustable frames will support our mattress without requiring a box spring. The space between individual slats should be fewer than 5” for the right support.
You will need to purchase a box spring or our Box Foundation if your frame does not already provide that support — e.g., if you’re using a metal frame like our Metal Base, or if the slats on your platform bed are further than 5” apart.
