Queen 12 Inch Memory Foam Mattress in a Box - Cooling Knit Cover

In this review the Queen 12 Inch Memory Foam Mattress in a Box earns strong marks for anyone seeking a supportive, cooling all-foam bed without complicated setup. The single biggest reason to buy is its combination of a breathable cooling knit fabric cover and a three-layer memory foam build that provides firm, contouring support and noticeable temperature regulation for sleepers who overheat. Setup is straightforward and the mattress expands at home after being unboxed, making it a practical choice for many bedrooms.

Key Features

• Cooling Knit Fabric Cover: The cover stays cool-to-the-touch and improves breathability so heat is moved away from the body for more comfortable nights.
• Three-layer memory foam: Layered foams cradle the body to reduce pressure points while maintaining the firm support customers report for back alignment.
• Temperature regulation: The fabric and foam combination helps evaporate sweat and feels less prone to trapping heat than many traditional foam mattresses.
• CertiPUR-US & Oeko-Tex certified: Independent certifications confirm the foam and fabrics are free from many harmful substances for added peace of mind.
• Easy setup: The mattress ships compressed in a box and restores to its shape within about 12 hours on any standard bed frame or platform.
• 10-year limited warranty: A long warranty covers defects, supporting a worry-free ownership experience when the mattress is kept in normal use.

Who It's For

This mattress is well suited to sleepers who prefer a firmer memory foam feel with reliable back support and pressure relief. People who sleep hot or sweat at night will appreciate the cooling knit fabric cover and the mattress's breathability. It also fits a wide range of frames, including slatted platforms and adjustable bases, making it a flexible choice for many bedrooms.

Lightweight side sleepers who want a very plush, contouring pillow-top may find the firm memory foam less yielding, and those needing an innerspring bounce should look elsewhere. Also note the product cannot be returned once opened, so buyers who need an extended trial should consider that policy before purchasing.
