14 in Firm Queen Mattress in a Box - Cooling Copper Memory Foam

Our review of the 14 in Firm Queen Mattress in a Box finds it best for sleepers who need solid, supportive surface and cooling performance without chemical concerns. The single biggest reason to buy is the combination of a firm, pressure-relieving copper memory foam layer with a breathable graphene knit cover that stays cool and resists odors. Unboxed and expanded easily, this mattress targets people with back pain and those who prefer a firmer feel while still enjoying memory foam contouring.

Key Features

• Cooling Graphene Cover: The graphene knit fabric wicks away heat and moisture for a cooler sleeping surface and the hidden zipper makes the cover removable for easy cleaning.
• Copper-Infused Memory Foam: The Aerofusion copper memory foam contours to the body to relieve pressure points while copper helps reduce odors and irritation.
• Firm Support: The 14 in profile delivers a noticeably firm feel that supports spinal alignment and is recommended for back sleepers and those with back pain.
• CertiPUR-US and Oeko-Tex Certified: All foam and fabrics are tested for harmful substances, giving buyers a clear assurance about chemical safety.
• Effortless Setup: The mattress ships compressed and rolled so it is easy to carry into a bedroom and expands to full shape within about 24 hours.
• 10-Year Limited Warranty: The mattress is backed by a decade-long limited warranty for long-term peace of mind.

Who It's For

This mattress is a good match for adults who prefer a firm sleep surface with reliable pressure relief, particularly back sleepers and those who wake with lumbar pain. The cooling graphene cover and copper-infused foam also suit warm sleepers who need a breathable option that resists odors.

It is less suitable for people who want a plush, pillow-top feel or side sleepers who generally need a softer surface for shoulder and hip cushioning. Also note the mattress cannot be returned once opened, so buyers who want a trial period should consider that policy before purchase.
