Best nap mat?

[jasmine_bay]

Emily will be going to preschool starting next week. One of the things we need to bring is a nap mat. I've found a few online, but wanted to check with other BBBers to find the "best" one. You gals and guys are so good at spotting the best baby products. I didn't want to out and buy a mat only to find out later that there was a better one.

Well, this is to be used more with a cot than as a standalone nap mat, but the prints and design are adorable.

Now that is a DIY preschool! I just take for granted that Toby's school assigns each kid one. Probably DIY is more sanitary I suppose. Maybe a nice thick exercise mat?
