The dorm-and-guest-bed classic — softens a firm mattress without rewriting the support core
About $45–$90
Two inches of gel-infused memory foam is our usual starting thickness: enough to take the edge off a firm innerspring, not enough to hide a broken mattress. CertiPUR-US foam; sizes through king. If 2" still feels firm after two weeks, step to 3".
Who it's for: Students, guest beds, and anyone testing softer feel before a mattress swap.
Skip if: Mattress already sags in the middle — replace the mattress.
