I ordered an IKEA day bed recently for one of the kids. There were several boxes, but the mattresses came rolled and vacuum-packed. I thought I'd been sent a couple of quilts but when you open the mothers they bust out like the incredible hulk, except they're not green and don't have a bad temper. Some day I'll Google HOW they get a mattress that big packaged down so small. Meanwhile, they're comfy matresses, obviously no springs tho.
