I'm giving this a temporary 3 stars, because Wayfair will not stop pestering me to write a review. The mattress is  still in the box, because we're not quite ready to set up the hide-a-bed yet. All I can say at this point is that the mattress came promptly and was a good price.  I'll update my review when we've actually used it.

Pros: Arrived promptly, good price
Cons: Wayfair won't stop pestering me for a review.
