How mattresses in a box work

The Ascension Appalaches mattress is subject to compression technology enabling it to be sealed and sold in a box. In no way compromising the quality of the product, this compression technique enables the mattress to be placed into a large bag from which a maximum amount of air is then removed, thus reducing the size of the mattress which can then be easily shipped to you or can be purchased and brought from LA PLACE to your home with no delivery wait time. To use your mattress all you need to do is remove it from the bag, carefully open the plastic wrap and allow it to slowly roll out until it has regained its perfect shape, in a matter of hours... All that's left is for you to snuggle up!

Did you know? LA PLACE mattresses in a box or in a bag (rolled and vacuum sealed) are necessarily comprised of high quality materials. Find out more about mattresses in a box »
