For the convenience of transportation, vacuum packaging is used, so note that the mattress topper may appear thinner upon opening. Please leave it in a ventilated place for 72 hours to let the smell of the new foam dissipate and restore the fluffiness of the mattress pad (it takes longer in winter) before use them. 3.
