Although the instructions say for ages 6-12, I bought it for my 2 yr. old.  She absolutely loves it and I don't see how she could get hurt on it.  If I get 5 years out of this it will be money very very well spent.  The size is perfect for a child anywhere between the ages of 2 &9.  There's plenty of room for them to jump around.  The enclosure zips one way (not like a tent where it zips vertically and also horizontally on the bottom) which makes it extra safe- although a little more difficult to move in and out of.  Still, my 2 year old can now enter and exit the trampoline by herself (the height of the tramp is just high enough that it's a little challenging for her to climb into it- but doable).  She even zips herself in and out.  I have complete peace of mind when she's playing on her trampoline even if I can't get out there to complete the zip all the way and do the clasps over the zipper.  I got the red and it's a deeper red like the picture indicates.
