This is a really great mattress.  It came relatively quickly and was packaged well.  I will say the day I brought the mattress into the house, was the same day a pile of ants was also found in the house...coincidence?  I don't know--

But the mattress was sealed tight.  The instructions say to open it up within 72 hours of delivery and let it breath for up to 72 hours but "you can use it in the meantime"?  This makes no sense!I laid on it about 5 hours after opening and it was soggy....let it breath the entire 72 hours!

After 72 hours it was perfect. Firm, but not too firm. And well made.  There was no bad smell or anything like that.  Comfy and good for the guest room.

One star off b/c of the ants....can't say for certain! Would buy this mattress again.
