Any room in our condo
We use these for our 6 month old who is just learning to sit up and also crawl. We can remove them when she is not using them or playing on them, as our condo is not big enough to leave them out all the time. This is a great product for our limited space situation, as they store easily in the closet! We purchased 12, but depending on where we set them up, we only use as many as needed for playtime!
