Frequently Asked Questions
How do I know if I need a mattress topper?
Consider a topper if your mattress is too firm or soft, you experience pressure points, your mattress is aging but still supportive, or you want to try a different feel before buying a new mattress.
Will a topper make my mattress too soft?
Our calculator considers your current mattress firmness and preferences to recommend the right thickness and material. A properly chosen topper should achieve your ideal firmness level, not make it too soft.
How long do mattress toppers last?
Quality varies by material: memory foam toppers last 3-5 years, latex toppers 5-8 years, and down alternative toppers 2-3 years. Proper care and rotation can extend lifespan.
Do I need new sheets for a thicker topper?
Toppers over 5cm thick may require deep pocket sheets. Our calculator will warn you if your recommended thickness might affect sheet fit and suggest appropriate sheet depths.
