These nap mats are great quality - we are going strong on 3 years and counting with no damage in any of them. One did arrive with a tear - but Lakeshore replaced it immediately at no expense on our part. Love the colors, too!

These sleep mats work perfect for our purposes but don't work for all children. For example, wiggly toddlers and children who sweat when they sleep... some kids are either soaked when they wake or not even on the cot itself! But it works for most kids, and that's good enough for us. We use cots with breatheable netting-like fabric about 2 inches off the ground for the wiggly and sweaty ones. ;) We'll probably order more soon!
