I’m so glad I trusted all the other reviewers and bought this bed — it’s firm yet comfortable and my sleep quality has definitely increased.  We bought a king size — really heavy to get upstairs, but you literally remove the plastic and the mattress is ready to go almost immediately (we let it sit for a night just to make sure it had finished inflating, but I don’t think that’s necessary).  I’m glad the bag it came in had handles — that did make transporting it a bit easier.
