I would estimate this trampoline to be 3/4 the size of a full trampoline. This was exactly what we were looking for because we purchased it for a two year old and a four year old for winter jumping in the garage in snow country. The posts that hold up the net just clear the garage door opener chain. It is very sturdy. It seems very safe. It feels solid at all times, even when used by an adult (label on the frame indictes the maximum weight at 175 lbs).
It took two adults two hours to assemble it. 30 minutes of that was spent backtracking and reassembling at one point, but hey, how many people mange to follow the directions to the letter the first time through? It was the alignment of the net that we got wrong. If you are not good at following directions recruit someone to help you that is. There is only one right way to build this. They only give you two spare screws. All other pieces must be used. You don't want any other pieces leftover when you are done.
The height of the pad is about armpit high on the two year old so he needs a little chair or step to help him climb in but he can drop off the edge, feet first, to get out. Bigger kids can climb in and out easily because the height is perfect for kids.
This trampoline was an unbelievable value. We expect the kids to have years of fun on it. Walmart's price beat everyone else's. We got free delivery right to the house. Since the box weighed 84 lbs it was nice to have it delivered. Thank you Walmart and FedEx!
