We bought this rebounder as a mini trampoline for our 3 year old daughter to use inside the house as a replacement for the air mattress that she was previously using as a trampoline. We received it a day and a half ago and it has been the center of attention since. At first she was a little less than impressed because she did not get much bounce on it but over the past day and a half she has become increasingly more attached to it. She likes to use it to do a quick bounce here and there rather than constantly jumping on it for a long time though, she does bounce on it for a couple minutes at a time when she is really enjoying it. I think it helped that I have been jumping on it a bit to try and loosen up the bands for her.When I was looking into mini trampolines I was having a hard time understanding what each one had to offer so I will try to clarify some things I came across in questions and reviews.First, Yes, a child can use it. Our 3 year old has no problem jumping on it all by herself without a bar to hold on to. She does like to hold on to my hands or my husbands sometimes to get some really high, more uncontrolled bounces in but, overall, she does just fine on her own. Also, this is quite stable. I was concerned about stability given it is foldable and, due to it only having 4 legs in the photo. The way it folds is opposite to the direction you jump so, it is unlikely that it will ever cause a problem because it would have to fold "up" on them. Also, it took a significant amount of strength to unfold it and snap it into place. I don't think that even my weight could fold it back up again, even if it folded the same direction I would jump on it. lastly, about those 4 legs....there are actually 6! The photo is incorrect and for whatever reason, the question on here that asks about the number of legs has mixed answers between 4 and 6. There are absolutely 6 legs on this. I am pleased as it makes it very stable. She has stepped with all her weight, on the very edge of the bar, between two legs and it didn't tip over...though I definitely am not a fan of her doing that and we have talked about not doing it since. :)Answers to some other questions - I am a 34 year old, average strength person and I was pretty much able to open this on my own. I say pretty much only because my husband was there, holding the unfolding edge to "spot" me. I would have done it on my own had he not been there but, as other have said, it is SCARY to unfold. I stepped on the one side of it and used both of my hands to push with my whole body to open it up and it gets really, really, tight toward the end...and very loud...very scary. Once it was unfolded it did not seem like it would fold itself up again though I was very cautious for a bit, not allowing our daughter near it while we put on the safety pad. Now, putting on the safety pad over the bar/bands would be really difficult to do with one person...perhaps even impossible. It is very hard to have it stay in place while stretching it with all my strength to get it to take the next curve. We figured out that there are leg holes in it, so be sure to start it on the right side, with a leg hole already around a spot where the leg will screw in. This makes it stay in that spot and allows you to pull it more without it just sliding along the bar. One thing I want to say, which others have mentioned, is that the instructions were confusing. The instructions mention the secure pins with wire ring needing to be in the bar and secured properly but it seems unclear what that means because they come on the rebounder exactly the way they show in the photo (okay, so you are just checking that nothing came loose in transport as they are for safety...) and you unfold it after it mentions the secure pins and it doesn't mention them again. So, by my understanding, the secure pins just stay exactly as they are and you do nothing to them even after you have just used incredible force to unfold this thing. They don't move, you don't do anything to the pins nor the wire ring. I do not see how they could possibly be useful but, I am not in the trampoline safety business so, I just left them. I felt secure in the other points I mentioned previously to be able to let this go. :) After getting the safety pad on it was very easy to screw in all 6(!!!) legs and flip it over to begin jumping.We have not attached the resistance tubes or the meter so I am unable to comment on their ease of assembly or use. Though, it seems easy to assemble them according to the manual.If it wasn't clear, this rebounder uses large elastic bands instead of metal springs in its design. They seem to be a bit more stiff than metal springs but I wanted the bands for safety and noise control. They do both of these things well - I do not see anyone getting injured by the elastic bands as they are just big stretch fabric, and even when an adult is jumping, there is very little noise. Id say, about the same amount of noise as a person jumping on a carpeted floor....maybe even slightly less noise than that. And, regarding the stiffness of the bands, I believe these will become more stretchy over time as it already seems to be more bouncy than when we first started bouncing on it, and we have only had it for a day and a half.Overall, we, as a family, are very pleased with this product. It is a good quality product at a good price. Although the assembly is a bit scary at times and requires a lot of strength/coordination (safety pad), it really isn't too bad. I do not think anyone should turn away from this for fear of assembly. It is definitely do-able, just serious business. :) I recommend it!
