Do I Need a Box Spring With My Mattress?
By Bénédicte Pelletier
Wondering whether you need a box spring with your foam mattress? It’s a good question. When investing in a quality mattress, you want the right foundation to reap full benefits.
The truth is—most foam mattresses don’t need a box spring. Using your memory foam mattress directly on a slatted bed frame provides plenty of support and airflow to keep you cool and comfy through the night.

What Is the Purpose of a Box Spring?
Box springs are made out of wood and metal springs. Traditionally, they go under coil mattresses to help absorb shock, improve airflow, and provide a supportive base.
New-generation mattresses (like the Endy Mattress) have all of these features built into the foam, which eliminates the need for a box spring.
Benefits of Using a Box Spring With a Foam Mattress
While not necessary, you could use a box spring under a foam mattress. The added height or extra firmness might suit your personal preference better.
Height
A box spring will make your bed several inches taller. This can make getting in and out of bed much easier for people with mobility issues.
Style tip: Make sure the combined height of your box spring and mattress won’t cover your headboard!
Maximum firmness
By providing support across the entire bottom surface of the mattress, a box spring can make a noticeable difference in how firm your bed feels.
On the other hand, a slatted foundation supports you while allowing for more give, creating a slightly plusher sleep experience.
Warranty
Some manufacturers require using a box spring for warranty purposes, but not Endy. The Endy Mattress’ 10-year limited warranty is valid with or without a box spring—just make sure to use a base or foundation with gaps no wider than 3 inches.
