I purchased this mattress to put in my daughter's new bunk bed and she loves it! The mattress came vacuum sealed in a relatively small box, although very dense and heavy. Unpacking the mattress was a breeze after getting help carrying it up to her room. After unsealing the mattress, it fully inflated in a little over a day and I was very happy to find that mattress did not need airing out at all. A HUGE plus. Personally, I feel the mattress could use a touch more firmness, but my daughter loves the cloud-like feel the memory foam provides. If the little one approves, that's all the matters!
