Nice pad, but a little small for Pack n' Play (2009-06-21)
I like this pad. It is thick, comfy, and waterproof. Good quality. However, it is a bit small for a Pack n' Play, so has to stretch and bunches up the mattress (but, I am still using it). It's probably my fault for not checking the measurements, but just so anyone else knows that it doesn't fit Pack n' Play quite right.

Perfect fit! (2009-06-12)
This is exactly what I was looking for. It fits my old porta crib mattress perfectly.

fits DaVinci Crescent 50 Coil mattress well (2009-05-13)
Before ordering this mattress cover, I was concerned that it wouldn't fit the DaVinci Crescent 50 coil mattress because the mattress is 5.5" thick, but it fits perfectly. I've also found that the Koala Baby portable crib sheets sold at Babies R Us fit the mattress without a problem, and they're very affordable ($7-$9 each).

Very comfy and soft (2009-05-04)
I purchased this to use on a portacrib 3" mattress for my grandson when visiting. It is super soft and appears very comfortable. He actually slept very well.

Haven't had a chance to use this yet, but it fits the porta crib perfectly.
