The fact that you can buy a complete mattress and have it shipped is amazing in and of itself!  We have just opened them and put them on the platform bedframes that we also purchased from Wayfair.  I have no idea of the comfort when you sleep on the mattress overnight because the house will be sold with all the new furniture without it being used. However, I didn't give 5 stars because after just lying on the mattress to check the comfort, it was very firm (I had hoped it would be a bit softer).
