I purchased two of these for my baby girls crib since they worked so well for my oldest when she was tiny (before she moved around a bunch). They are plusher than some other sheet savers out there, and appear to be very waterproof. They seem to hold moisture, however, rather than letting it evaporate. Call me gross, but i tend not to change the sheet saver after every spit up, otherwise I'd be going through 8 of them a day. If I don't mop up the mess right away it stays wet for what seems like forever...where I have others that don't seem to do the same thing (those are twice the price). All in all, these are fabulous for the stages where your baby, for the most part, stays where you put her...which really only lasts the first month or two, then they almost become pointless because your baby will scoot here there and everywhere. As a second time mom, I know this now and didn't buy the more expensive ones, so knowing the difference now, I am pleased with my purchase...I just wish they didn't encapsulate the moisture so much.
