We LOVE this toddler bed. The trundle beneath was great storage for sheets, and small toys. A crib sized mattress will fit perfect on this bed. Great bed to transition from once they can crawl out of the crib. It sits low to the floor so we felt confident that if he rolled out of bed he would not be injured. This is a must buy. 

Pros: Great value. Sits low to the floor.
Cons: None
