We recommend allowing the new mattress to fully expand for 72 hours after unboxing. Please maintain a safe distance when opening the package during the mattress expansion process. Please note that the overall firmness of this mattress falls between medium and soft—it is not an extra firm mattress. Additionally, please follow these steps when unboxing: First, open the cardboard box. Then, lay the mattress flat on your bed frame. Finally, remove the plastic wrapping. When the mattress expands, keep a safe distance to avoid injury from being hit by the expanding material. We’ll be available online at all times—feel free to contact us if you have any questions. This full size mattress combines gel memory foam with innerspring to give you the perfect combo of comfy support and a little bounce. Its medium firmness gives a soft feel that cradles the joints without being too cushy.
