Is relatively small, in the bag provided. No comparison with a folding bed...... I find it good and practical.

Good day. The box that comes with the mattress is still quite big. The mattress can also be stored in a bag after use, which is included in the delivery. I would estimate the size as a supermarket carrier bag.
I myself recommend the mattress as it is great to sleep on. The air in the mattress remains well preserved even at higher outside temperatures. The material is pleasant. The material does not smell the first time you use it. You don't have the feeling that you are swaying back and forth like on a ship, but lie well and comfortably. Recommendable.
