Frequently asked questions
How thick should a mattress topper be?
For noticeable change, 3-4 inches is ideal. Thicker toppers provide more support and pressure relief but may affect sheet fit. Those over 4 inches can feel like a new mattress.
What is the best material for a thick topper?
Latex offers durability and cooling, while memory foam provides contouring. Gel memory foam balances comfort and heat dissipation. Choose latex for longevity and firmness, memory foam for plushness.
How do I choose between memory foam and latex?
Memory foam contours closely, great for pressure relief but can trap heat. Latex is more responsive and cooler but firmer. Side sleepers often prefer memory foam; back/stomach sleepers may like latex.
Will a thick topper make my bed too high?
Yes, adding 3-4 inches can increase bed height significantly. Check your sheets and bed frame clearance. Deep pocket sheets may be needed.
What certifications should I look for?
CertiPUR-US ensures foam is free of harmful chemicals and low VOCs. OEKO-TEX certifies fabric safety. For organic options, GOLS certifies latex, and GOTS certifies cotton.
