Guaranteed Better Sleep Quality-Furinno Angel and 2 in. Egg Crate HD Foam Mattress Topper allows you to adjust the comfort level of the mattress without spending a lot of money buying a new one. Gel-infused HD foam increases the breathability of the topper to reduce trapped body heat creating a cooler sleep environment. Egg crate shape design creates gentle massage feeling and more support for pressure point relief conforming to head and shoulder to provide spinal alignment for a great night sleep. Our foams are 100% CertiPur-US certified foams which means they are made without ozone depletes, PBDE flame retardants, heavy metals, formaldehyde and phthalates. Odor Disclaimer: Should you notice an odor when unpacking your new topper, do not be alarmed. This odor is harmless and will dissipate. Please let the topper air out in a well ventilated area for about 48-hours to return to its best shape. Our topper comes in four sizes and fits any standard Twin, Full, Queen or King beds.
