Out of Box item, may require some assembly. See link for more details:
Size: 10"- Full
Note: Out of box item, this is a full size mattress. This is folded in half and taped for transport but please note it is not in it's original vacuum seal, see pics. There is some warehouse dust/debris and some dirt spots on the bottom of the mattress, could probably just replace the mattress cover because it unzips and comes off.
