Care and longevity

After unboxing, lay the topper flat in a well-ventilated area to expand fully. In cooler rooms, expansion may take longer. For best results, consider a room around 78°F (26°C).

• Allow 48–72 hours for full expansion in a ventilated space
• Remove and wash the cover on a gentle cycle; air dry to preserve fabric
• This topper is designed to be used on top of an existing mattress, not as a standalone bed

The memory foam is CertiPUR-US certified, while the soft cover carries OEKO-TEX certification, underscoring a focus on safe materials and durable construction.
