A memory foam topper is the most popular way to soften an existing mattress -- and at $80-$250, it's dramatically cheaper than a new mattress. Here's what actually differentiates quality memory foam toppers from cheap ones.
What to Look For in a Memory Foam Topper
- Density: 3-5 lb/ft3 is ideal. Below 3 lb/ft3 wears out quickly (2 years or less); above 5 lb/ft3 is too firm and slow to respond
- Thickness: 2-3 inches for meaningful feel change; 1 inch for very minor softening only
- Certifications: CertiPUR-US certified means no harmful VOCs, formaldehyde, or heavy metals
- Cooling features: Gel-infused, open-cell, or copper-infused foam for temperature regulation

Frequently Asked Questions
Does a memory foam topper make a mattress hotter?
Traditional petroleum-based memory foam does trap heat. Gel-infused, open-cell, or plant-based memory foam toppers sleep noticeably cooler. If heat retention is a concern, consider a latex topper or a gel/plant-based foam topper instead of standard memory foam.
How thick should a memory foam topper be?
2 inches for moderate softening and feel change. 3 inches for significant softening -- can make a firm mattress feel medium. 4 inches is the maximum practical thickness; anything thicker can affect mattress support and stability.
