Comes exactly as pictured. The packaging says to open the topper up and let it expand and 'air out'. If you have the space and time, please do. The foam rubber-like smell is a bit strong. We let ours air out for about 4 hours before adding linen. Seemed okay. Longer would have been better though. Very comfy and didn't get hot like our original memory foam topper. The convolutions take a little getting used to as well, but I guess you can flip it over if you don't like the feel of it. Good purchase, good price.
