Our homes have a lot of hard surfaces. This is especially true of our floors--the prime play space for small children. Even in regular quiet play, kids fall down and bump things...like soft little heads.
That's why it is so important to give them a cushioned play area. Those little bumps are much easier on them.
Another big issue with children is keeping their play ground sanitary. With carpet or an ordinary rug, this can be difficult, if not down right impossible. Spills happen. So do burp ups and accidental potty issues. Mothers know to expect these things and plan ahead accordingly.
Well, these mats are great for that prior planning! The sturdy foam is very easy to wipe down and keep clean. No need to do an emergency load of laundry. (Just be certain that your cleaner of choice is safe for baby.)
The play mats featured here on this page all consist of interlocking foam tiles. The individual pieces are 12" x 12", and around 1/2" thick. So a 36 tile set would cover an area 6 foot by 6 foot. A pretty good sized area for a crawling baby.
You'll need to check to see if they come with extra pieces to "finish" the outside edges. Some do, and others don't. The edging isn't necessary, and some might even like the puzzle edging more than a straight one.
