This review is for the 60 inch round Seaside adventure trampoline with enclosure. We bought this trampoline as a replacement for the Skywalker 48 inch round bounce trampoline with enclosure(also available for sale on Amazon) The assembly of this trampoline took 60 minutes for 2 adults to accomplish. I didn't find it at all difficult to assemble; however, this isn't my first rodeo. Having stumbled and cried my way through the assembly and take down of our first skywalker trampoline , we were old pros when it came to this. There are YouTube videos dedicated to explaining the assembly process . My recommendation to anyone with a short temper is to check one of those out before beginning. All of the necessary tools are included to assemble this, but I found that using a power drill speeds along the process. After this bad boy is assembled, your kids will all try to crowd in at once to jump. My 70 lb 13year old, 30lb 3 year old, and 50 lb 10 year old all squeezed in and starting jumping. It supported their weight (the suggested and safe max weight to use this is 100lbs), but it wasn't all too much fun because it didn't leave any of them room to maneuver. Ideally, this trampoline works well for 1 person at a time, but it can comfortably accommodate up to 2 children with a combined weight of 100lbs or under. I had three 3 year olds in it at the same time which worked reasonably well, but as they began to get wound up, they began knocking into each other. Children who are still working on balance will get use out of the bar that circles around the interior perimeter of the trampoline netting. The bar is sturdy enough for a child to hold onto whilst jumping without causing the trampoline to tip. Children might be tempted to grab onto the netting while bouncing, but I would discourage this as the netting will tear when enough pressure is applied. I've never had it tear when the children fall into the sides, but it has torn when the older kids grab onto it for balance when jumping up and down. This trampoline uses bungee cords in lieu of springs. Not having springs means no pinched fingers or toes, but it also means sacrificing a bit of the bounce that you'd get from a typical trampoline with springs . Since we bought this trampoline with our toddler and kids under 7 in mind, we feel that the bungee cords were the better choice for us. If we were looking for our tween and teenager, we'd for sure look for a trampoline with springs. Our 3 year old has slammed himself all around on the trampoline and has never gotten hurt. I feel the styrofoam covers over the metal bars provide enough cushioning to prevent the sting that would happen if you smacked up on the bare metal bars. Because we bought our trampoline for indoor use, we find the 60inch to be a bit too big . We miss the smaller footprint of the 48inch skywalker trampoline we owned prior to this- which comfortably fit into a the corner section of my son's bedroom. The 48inch was suitable for 2 small children but ideally for 1 small child (I would say 5 and under). If I could do it over, I would probably go back to the 48 inch because our trampoline is typically only used by one child who is 3 years old and the added jump space wasn't necessary. If your hopes are to use this with multiple children or for children who are 5 and up, I would say that the 60inch is a better choice for you. And although I do enjoy the smaller footprint of the 48inch, the 60inch is still manageable for indoor use. I can't attest to the longevity of this product but, for the price I paid, I would be pleased if it lasted 1 year (but I feel it's made well enough that it will last longer). For reference, my first trampoline-the Skywalker 48 inch- lasted us from November 2014 until June 2016. The actual trampoline mat, bungee cords and the metal poles were in great condition, but the netting and the styrofoam had torn. The only valid complaint I have about this product - meaning a complaint related to the product itself as opposed to my personal preference- is that my kids' feet are stained black from the mat when they get off of the trampoline. I don't know if this is a temporary problem or not. I have been making my children put on socks when they go in and then have them remove their socks when they get out so that they don't stain my carpet. And I fully believe the black would transfer onto the flooring since that's actually how I discovered the problem to begin with...lots of black smudgy footprints on our white bathroom floor ????. Because of the black from the mat rubbing off onto my children's feet (which creates a hassle for me), I am docking this 1 star. Edit: the black on the mat no longer rubs off. As this was a temporary issue, I'm moving my rating up to 5 stars I'm including a picture to compare the sizes of the Skywalker 48inch round trampoline and the Skywalker 60 inch round trampoline. The pic shows my 3 year old son and my 10 year old son.
