      the person who slept on it while visiting family members actually asked me that! I expected a smaller box than usual, because I read reviews of the mattress. But I expected the box to be tall and thin. We were so surprised when the box turned out to be about 4 feet tall, with a square diameter of about 4 feet, too. It wasn't exactly a light item. My daughter had to help me push and shove the box up the stairs. I managed to get it into the space allotted for it, and then began opening it. The box was easy to open. But inside, layers of heavy plastic wrapped around the mattress again and again. I was standing at the part of the package where the head of the mattress would go. I snipped and snipped away with my scissors until - SPROING!!! - the mattress suddenly opened and unrolled itself. It's s good thing that I am not a prideful person, because it knocked me off my feet. But slowly, do I am I injured. Like other reviewers said, it seemed to reach its maximum height of 12" almost immediately. We put it on a trundle, and st first weren't sure if it was too high to go under the main bed! It fit, but barely. You already know what the person who used it thought of it! She'd like to buy one just like it for home!

      My daughters like them so much, don't want to wake up and leave the beds. I was quite surprised how quickly it recovered. You won't be disappointed if you decided to buy. Very comfortable.

    Questions & Answers

    • Q:

      "Is it memory foam? It says coil, but how does it come rolled up or compressed into a small box?"

      • A:

        it is not memory foam, it is an inter-spring mattress. It is rolled up and compressed, wrapped in plastic and sent in a box. Once you remove the box and plastic - the mattress will unroll and it takes a few hours to reach the maximum height of the mattress. It is very supportive and just as good as one you buy at a mattress store.

      • A:

        I'm not sure what innerspring is comprised of but it is not the traditional coil system. I can tell you this- it is extremely comfortable and wears very well. It has good support as well. I though it was worth every penny!

    • Q:

      "Do regular size twin kid sheets fit this mattress?"

      • A:

        tes...regular twin sheets fit. My son loves this mattress

      • A:

        Yes. Perfectly!

      • A:

        Yes, I purchased this mattress for my daughter and have had no problem buying sheets that fit. As a matter of fact I am going to be buying a Queen size for myself! :)

      • A:

        Sorry, I'm not sure if there is a difference between "kid" sheets and regular twin sheets, is there? Are you speaking of toddler bed size? If toddler, then no. However, regular twin (not dorm "XL") will fit with no issue . I hope this helps!
