Memory Foam Mattress Buying Guide

How memory foam works, what to compare, and which specifications matter when shopping.

What memory foam changes

Memory foam is valued for contouring and pressure redistribution, but mattresses differ widely in how much memory foam they use and what sits beneath it.

Compare the whole mattress

Look at total profile, comfort-layer thickness, support core, cover design, return policy and whether the manufacturer discloses useful material specifications.
