A foundation is a bed base constructed using a sturdy wooden frame and in some models a steel non-flexing spring. The purpose of the foundation is to raise the mattress’s height, making it easier to get in and out of bed and to create a flat and firm structure for the mattress to lie on. With the increasing height of mattresses, you have the option of a “regular profile” box spring 8-1/2” in height or the “low profile” box spring at 6”. Changing the height of the box spring will not affect the support of feel.
Most of our models are sold using our Heavy-duty foundation also known as a Semi-Flex® Performance Grid foundation. A Semi-Flex offers a steel wire foundation combination which is better than all-wood alternatives because it’s stronger, lasts longer, and doesn’t squeak or crack like wood does over the years.
