Look at the Facebook reviews. They are selling flimsy changing pads as "custom
Size mattress." These are not mattresses!
They are plastic and cheap and not an ounce of firmness. They would be dangerous for an infant and create suffocation risks. And they claim these are custom mattresses and because of that sale is final. I've even bought more firm changing pads - these are like the cheap changing pads that you could fold up into a ball. Terrible. $45 for that!
