Fits an 11" deep mattress.  Chose this bed because it has a high weight limit.  Very easy to put together (my 89 year old mother was my assistant)).  It was very sturdy and didn't make noises when I rolled around on it to test it.  Had no issues with delivery (which was in about 3 days).  The box was in perfect condition (not torn up at all).  All the parts were included with a few additional pieces, which was nice.  Fortunately, I had zero issues unlike some of the other reviews I had read.  I would most definitely recommend this bed to anyone.

Pros: See above
Cons: Absolutely none!
