Mattress Depths Review
There are no standard mattress depths. Some mattresses are 9-10 inches deep, but many pillow top mattresses measure 15-16 inches in depth, or more. Box springs and other bed components can make the mattress even higher.
If you’re making a quilt for yourself it’s much easier to consider all the bed size “what ifs.” If the quilt is a gift, you can’t be sure which bed size it will ultimately be used on, so consider making a quilt that would fit a queen mattress, the most popular bed size.
