Amazon Basics Cooling Gel Memory Foam Mattress Topper — 3-inch Queen, CertiPUR‑US Comfort

This is a 3-inch, queen-size Amazon Basics memory foam mattress topper infused with cooling gel for added comfort and pressure relief.

Give your mattress a noticeable comfort upgrade without buying a new bed: this Amazon Basics topper adds contouring support and temperature-managing gel to most standard queen mattresses. The foam is CertiPUR‑US certified and manufactured in the United States with imported components, arrives compressed for easy shipping, and regains full shape within a few days.

How does this topper improve the feel of my current mattress?

The memory foam layer conforms to your body, redistributing weight and reducing concentrated pressure points for a softer, more supportive sleep surface. It works on innerspring, foam, and hybrid beds to deliver a more uniform feel.

• 3 inches of memory foam for deeper contouring and support
• Helps reduce discomfort on hips and shoulders by evening out pressure
• Simple way to soften a too-firm mattress without replacement

Will the cooling gel keep me from overheating at night?

The foam is infused with a cooling gel formulated to help draw heat away from the sleeping surface, so you experience a cooler sensation compared with standard solid foam toppers. It aids surface temperature regulation but doesn’t replace breathable bedding or a cool room.

• Gel infusion dispersed through the foam to assist heat dissipation
• Best when paired with breathable sheets and good bedroom ventilation
• Not a substitute for active cooling systems, but a practical passive option

How do I unpack and care for this topper?

The topper ships vacuum-sealed for compact delivery; unroll it onto your mattress and allow up to 72 hours for the foam to fully expand and off-gas. A temporary new-foam scent is normal and fades with ventilation; spot-clean only per manufacturer guidelines.

• Arrives compressed — unroll and let it expand for up to 72 hours
• Minor initial odor dissipates in a well-ventilated room
• Spot clean and avoid machine washing to preserve foam integrity
