What is a Low Profile Box Spring?
Same Support, Shorter Height
A low profile box spring (also known as a low profile foundation) serves the same purpose as a normal box spring, but has been slimmed down to compensate for the increasing heights of modern mattresses.
A traditional box spring with a modern mattress is likely to be 4-6 inches, or more, taller than a traditional box spring and old two-sided mattress. Many dislike the increase in height, for aesthetics or being farther from the floor, and the low profile box spring is designed to reduce mattress height closer to what was standard a few decades ago.
Many manufacturers produce low profile box springs and they provide the same amount of support as your standard box springs, they are just shorter to reduce the height of the sleep set. Standard box springs measure 9 inches in height, and low profile box springs measure between 5 and 5.5 inches. The difference in height has no effect on the amount of support they provide to the mattress, and both work with all mattresses and virtually all beds
