Once you've unboxed your Endy Mattress and removed the plastic wrapping, it will immediately expand to its full size in a few seconds. If the mood strikes, hop on and take a nap right away; while the mattress's core will take a couple of days to stabilize, using it right away won't cause any damage. Make sure you have the best foundation for your new mattress.
Your Endy Mattress will reach full firmness within about a week, and maintain perfect comfort for its lifetime. And that's it! Happy sleep for the next 10 years!
