Emma mattresses are cleverly packaged in an easy-to-move cardboard box. We use a special vacuuming process to gently compress and roll your mattress, so even the largest mattress can fit inside. This space-saving method is kinder to the environment and takes up less space on our delivery trucks. The Emma mattress takes up to 2-6 hours to fully inflate. Please also note it is not entirely uncommon for the mattress to take longer to inflate to its full size. Although it is rare what can sometimes happen is that the mattresses are vacuum packed slightly tighter which just leads to a little more time for the full inflation to take place. Although they should reach 90%-95% of the desired depth within 48 hours, it may take an extra couple of days for them to reach the optimal height.
