12 in Green Tea Cooling Memory Foam Mattress Queen - Fiberglass Free

Our review of the 12 in Green Tea Cooling Memory Foam Mattress, queen size, finds it best for sleepers who want a medium firm feel with enhanced cooling and low chemical exposure. The single biggest reason to consider this mattress is its cooling gel memory foam top layer paired with CertiPUR-US and OEKO-TEX certified materials, which together offer pressure relief while reducing heat buildup and avoiding harmful chemical treatments. It ships compressed in a smaller box to cut packaging footprint and includes a 10-year limited warranty, making it a practical choice for eco-minded shoppers who value breathability and supportive foam.

Key Features

• Cooling gel memory foam: Top layers include gel-infused memory foam that helps regulate temperature and reduce night sweats for hot sleepers.
• Pressure-relieving support: Memory foam contours to the body to ease pressure on hips and shoulders and improve circulation overnight.
• CertiPUR-US certified foam: All foam layers are tested to meet standards for emissions and durability, reducing exposure to harmful substances.
• OEKO-TEX certified cover: The mattress cover is produced without harmful chemicals to provide a cleaner sleep surface.
• Green tea and charcoal infusions: Natural infusions help maintain freshness and reduce odors for longer between cleanings.
• Smaller shipping box: The mattress ships compressed in a reduced-size box to lower the product's carbon footprint during transport.

Who It's For

This mattress is a good fit for back and combination sleepers who want a medium firm support profile with pressure relief and cooling properties, and for anyone concerned about certified safe foams and fabric. It also suits shoppers who appreciate value and a long warranty without paying for luxury innersprings or hybrid constructions.

Side sleepers who need very soft cushioning or heavier sleepers seeking high-density support may want to look at thicker or hybrid models instead, since firmness opinions vary and some users report the mattress feels firmer than expected.
