This Mellow 4-inch ventilated memory foam mattress topper adds contouring support, cooling airflow, and a calming lavender scent to refresh a worn mattress instantly.

Replace the feel of an older bed without buying a new mattress by layering this Short Queen topper from Mellow. Made with CertiPUR-US certified memory foam, the 4-inch profile cradles pressure points while its open-cell, ventilated design encourages air circulation to reduce trapped heat. A subtle lavender infusion is blended into the foam for a gentle, natural scent that many people find relaxing at bedtime. The topper ships compressed and typically regains full shape within 24–72 hours depending on room temperature.

How does this topper change the feel of my existing mattress?

The Mellow topper adds a thicker, pressure-relieving comfort layer that responds to your body temperature and weight. It smooths uneven surfaces and provides full-body contouring so you feel less pressure on hips and shoulders. Motion isolation features help reduce partner disturbance on shared beds.

• 4 inches of memory foam for deep contouring
• Responsive active suspension to minimize motion transfer
• Even weight distribution to reduce pressure points

Will this topper stay cool during the night?

The foam uses a ventilated/open-cell construction to promote airflow through the topper, which helps move heat away from your body. Improved circulation of air reduces heat buildup compared with solid foam layers. For best results, pair it with breathable sheets and a mattress foundation that allows airflow underneath.

• Strategic ventilation channels for continuous airflow
• Open-cell memory foam reduces trapped body heat
• Works well with breathable bedding to enhance cooling

What does the lavender infusion do and how strong is it?

The lavender is blended into the foam to provide a light, natural scent intended to contribute to a calming bedroom atmosphere. It is not a topical product and does not release strong odors after an initial airing period. If you prefer no scent, allow the topper to air out fully after unboxing to dissipate any mild manufacturing fragrance.

• Subtle, built-in lavender infusion for a soothing scent
• Not a topical spray—scent is integrated into the foam
• Air out after unpacking to minimize any initial aroma

How long until the topper is ready to use and is it safe?

The compressed topper typically expands to its intended thickness within 24–72 hours; warmer room temperatures speed up expansion. The memory foam is CertiPUR-US certified, meaning it meets standards for emissions, durability, and content. The product is covered by a 3-year manufacturer's warranty for manufacturing defects.

• Expansion time: usually 24–72 hours from unpacking
• CertiPUR-US certified foam for emissions and durability standards
• Includes a 3-year manufacturer's warranty for defects

Who is this for? The Mellow 4-inch ventilated lavender memory foam topper is ideal for sleepers who want to revitalize an aging mattress affordably, those who need additional pressure relief without replacing their bed, and anyone who prefers a lightly scented, naturally relaxing sleep surface. It suits combination sleepers, couples seeking better motion isolation, and people who want improved airflow and contouring comfort in a Short Queen size.
