Most of the time, but not always. We usually have that information in the Product Details section of the page where you order your bed. If it’s not there, find your bed on our mattress and foundation chart. You don’t necessarily need an Ethan Allen mattress and foundation for an Ethan Allen bed (although we’re partial to them!), but the chart can at least give you an idea of what’s required for a safe, healthy night’s sleep. You can also see if your bed is compatible with our adjustable bed base.
