Frequently asked questions
How thick should a memory foam mattress topper be?
A 4-inch topper is ideal for significantly softening a mattress or adding support, while 2-3 inch toppers provide minor adjustments. Thicker toppers offer more pressure relief but may require deep-pocket sheets.
Will a memory foam topper make my bed sleep hot?
Traditional memory foam retains heat, but many modern toppers include cooling gels, graphite, or breathable covers. Look for gel-infused or latex options if you sleep hot.
How long does a memory foam topper last?
Most memory foam toppers last 3-5 years with proper care. Higher density foams (4-5 lb/cu ft) tend to last longer, while budget toppers may sag sooner.
Can I use a mattress topper on any mattress?
Yes, toppers work on innerspring, memory foam, latex, and hybrid mattresses. Ensure your mattress is in good condition, as a topper cannot fix severe sagging.
What certifications should I look for?
CertiPUR-US ensures foam is free from heavy metals and formaldehyde. OEKO-TEX Standard 100 indicates no harmful chemicals. GOLS certifies organic latex.
