At first, I was very surprised to see an innerspring mattress arrive all rolled up in a box. I thought that only memory foam mattresses could be rolled up  boxed like that. But the unboxing was fascinating! The mattress was vacuum-packed and hissed into form once I cut the plastic. Definitely a learning experience! Once I got over that excitement, the mattress was very comfortable and exactly what I wanted. So much so that I ordered one in queen for the guest bedroom.
