"Bought it for the Dream On Me 2 in 1 Portable Folding Stationary Side Crib- Fits well with a small adjustment"
The mattress [pad] that comes with the Dream On Me 2 in 1 Portable Folding Stationary Side Crib, Espresso is a joke- extremely thin and provides no support for baby. Bought this mattress after reading a ton of reviews and although it's slightly more expensive than the other portable crib mattresses it was worth every penny so baby is comfortable. You should note that their is a little bit of a gap at the foot/head of the crib when the crib base board is set to its lowest setting- but that's only when the Dream on me mattress is in the crib by itself- I solved that problem by leaving the mattress pad (that came with the crib) in the crib and putting the Dream on Me Mattress on top of it- no gaps!
Now I have to find sheets to fit this mattress!!!
Hope this helps!!!
