We have a 14.5" king mattress w/ low profile box spring and the sides of the quilt are a bit too short for my liking.  If you have a platform bed w/ standard mattress, you'll be fine.  The quality of the set is very nice and, so far, is holding up in the wash.  The colors are very nice, also.  A good buy... I just wish the quilt was longer on the sides to fully cover the mattress and box spring.

Pros: Very pretty, vibrant colors, holds up well, soft.
Cons: Could be longer on the sides, for sure.
