Mattress Foundation & Bed Base Guide

How platform beds, slats and foundations interact with mattress support requirements.

The base is part of the system

A mattress needs appropriate, even support underneath it. The exact requirements can differ by manufacturer and mattress type.

Platform beds

Platform frames can provide broad support directly under the mattress. When they use slats, spacing and center support become important details to verify.

Traditional foundations

Modern foundations are not always the same as old spring-filled box springs. Follow the mattress maker's current support requirements before reusing an existing base.

Why this matters

An incompatible support setup can affect feel, durability and warranty eligibility.
