    Cook mattress

    Very prompt delivery, and who would have thought a mattress could be vacuum packed and rolled up intointo a box, which made for a bit of fun for my dog when I cut the package open. Im stoked with the mattress, which is very comfortable .

    I would never have believed that you could squeeze a full inner spring mattress into a small box.

    I was in awe to see it grow before my eyes.
