My experience as a customer of JumpKing trampolines

Why this is here
My experience as a customer of JumpKing is posted here online because I am hoping to gather similar experiences from others and hopefully raise their anti-consumer practices to the correct authorities. If you have had a bad experience with JumpKing trampolines, please reach out to me at my email address, which is simply "mail" (at this domain name).
If you are a representative of JumpKing, the damage is already done, but it would be nice if you refunded my money.
Background
I purchased a JumpKing 10' x 16' Pro rectangle trampoline in June of 2026. These are available on Amazon and from retailers such as Home Depot because the company is so large. They are owned by a giant umbrella corporation called YJ Corporation. It is possible that they made a good product at one point, but the trampoline we received is a poor product made of cheap parts with poor tolerances.
Poor Shipping
The first thing we experienced is that they ship you three large boxes, each weighing around 150-200 pounds, via a third-party freight company. They will not carry the boxes into your yard but instead plop them in your driveway for you to somehow deal with. That's just an inconvenience. You don't yet know that you have just been handed 500 pounds of quickly manufactured poor-quality material.
Poor Instructions
The assembly instructions are modeled after a large Swedish furniture manufacturer's famous instructions which consist of line drawings only, no words. Unfortunately, though, JumpKing does a far worse job. Their instructions are not clear and the assembly process is nowhere near as simple nor straightforward as the Swedish furniture company's instructions. It's not just that the content is poor. The provided diagrams are small and blurry. If you want to understand some detail or another, forget about it.
To try and make up for the poor quality printed instructions, they have some videos posted online.
Poor Tolerances
Once I had completed only the first few steps of the instructions, I ran into an issue that stopped me dead. Each corner is a piece that looks like a U. The vertical legs of the "U" connect into some pieces of metal that form a square corner for the rectangle. The U sits on the ground, to hold up and support the rectangle corner, which the trampoline stretches over. The issue that stopped me dead was that the U was supposed to slide into some mounts on the underside of each rectangle corner. It's a simple peg-in-hole situation, but the vertical parts of my U's did not line up at all with the corners. You do this upside down, and this is how far away the leg was from the hole it is supposed to slide into:
I measured this as an about six-inch gap. Actually, it was worse than this at first. Once I realized this was not even close, I went back over my pieces, ensuring that I had assembled the correct pieces together, and using a rubber mallet to tighten them up. One of the problems is they use super cheap thin metal, and each end is made to slide into another, and the manufacturing tolerances are so bad that you really have to work to get everything pressed together. This was my third or fourth sign that I had purchased a cheap product.
My father-in-law who is a former engineer laughed at me when I asked him to help me see if I could force the pieces together. He was a good sport, though, and we reefed on the metal pretty good before deciding that, for absolute certainty, something was not right. To actually get the pieces together would bend the metal.
I of course gave JumpKing the benefit of the doubt and assumed that perhaps I had been given the wrong pieces from another trampoline (they make more than a dozen models) so I looked over all the paperwork sent with the trampoline to find a phone number to call. There was nothing in the way of a number, and only an email address. I fired off an email to customer support:
Hello,
I began the assembly of the 10 x 16 Rectangle Trampoline and Enclosure we received this past week. (Order by *****, *** NE **th St., ******, WA 9***5).
As evidenced in the photo and video I am attaching and linking, the leg pieces once assembled are not even close to the right measurement in order to attach to the corner pieces.
Here is a link to my video https://share.icloud.com/photos/072Suj99D-IcZ_YTCxZlNa-bA
In case that does not work here is an unlisted YouTube copy of the same video https://youtube.com/shorts/Y4baS3Z1Hp0?feature=share
And attached a photo of the four pieces.
How can we resolve this?
Thank you,
Scott
Poor Customer Service
I waited a full day and this was their reply:
Hi Scott
The legs were made to pull and insert. Please see our assembly video at 3:18 for reference here.
Base on your video, the legs were made correctly.
Thanks.
Still giving the benefit of the doubt, I watched their assembly video again. I noticed that in the assembly video, the pegs were only an inch away from the hole. I screenshotted mine (which is the image you see above) and a still from their video (below), and sent it back to them showing the difference.
I reiterated to them that I have a multiple-inch gap and that we had already tried to bend the metal to fit but could not. ("I cannot bend steel multiple inches.") In addition to that, I made a photo gallery shared online with photos of all the pieces next to a tape measure, so that there could be no disputing the fact of the measurements.
Their response to this was mystifying. They simply stated: "The 1" distance on your trampoline is standard."
At this point, I was shocked. Over a week had gone by and I had gotten nowhere with them. I thought a bit and wrote down a reply:
I am starting to feel a little bit of frustration that you are not reading my replies. As I mentioned, it is a greater than six (6) inch distance between them. Not a one inch gap. Were you able to view the image gallery showing the tape measure against the pieces that are mentioned?
But it gets worse
They sent back the following reply:
Hey Scott
Please see link here that we video how the leg is assembled.
Thanks.
I never expected the customer service department of a company whose livelihood to be on the line to start actively trolling me, but this is exactly what they did. They knew that once they drop off the 500 pounds of garbage at your house, you're basically stuck with it. There is no recourse for you which doesn't cost as much or more than the $1400 you already paid.
We went back and forth some more on their customer support emails. I made a whole video showing that it was impossible for my father-in-law and I to bend the pieces to fit. Then got the same reply again about their assembly video. I wrote: "I hope you are having a great day today. Are you able to view the video I provided?" They wrote back: "Yes, we did. Did you see the video we share with you?"
I could just imagine this customer support woman smoking a cigarette in the back of a warehouse and laughing about another customer who couldn't use their product. But then I remembered Hanlon's Razor: "Never attribute to malice that which is adequately explained by stupidity." So I thought to myself, OK, she's just stupid. How can I help her understand?
With that in mind, I wrote:
Good to hear that you have watched my video! I have watched all the videos and links you have shared and I have put a lot of work, a lot more than most customers would put in in order to help you help me.
How do you believe that the video you shared is helpful here. Can you share more? Clearly in the video you have shared, with your pieces, the men are easily able to install the leg. It is clear that they start out with much less distance to cover. In short, their pieces fit. Since my pieces don't fit, I don't know why you think that showing me a video with pieces that fit does anything else but confirm that there is an issue here with my pieces.
What possible solutions do you have for me that can help prevent this from becoming just a dispute on the credit card. I would rather prefer that you support my problem by addressing it in some way. Respectfully, I can think of a number of ways for you to be helpful. You can provide the measurements I mentioned so we can be sure we're all talking about the same thing. You could just send new leg pieces if you believe that's the issue. You could suggest a lot of things here. I would really love to work this through to the place where I'm a happy customer. I assume you feel the same.
Scott
As you can tell, I actually was thinking about different possible ways to escalate the situation at this point. Escalating by disputing the charge on my credit card was one option. I also wondered if I should open a complaint with the Better Business Burea? Their Secretary of State (they are in Texas)? File a small claims court case for the $1400 I wasted on the unusable trampoline?
No Resolution
If you thought there would be a resolution to this story, there wasn't. JumpKing never did provide support for their shoddy trampoline once they sold it to me. I, on my own, engineered a way to bend the pieces so they would fit. When I did this with one corner piece, I filmed it and sent it to them. In my email to them showing that I was just taking matters into my own hands, I asked them if their warranty would be voided by this.
Their reply:
That's a safe and creative way of putting the legs in, and It will not void warranty.
Well, at least I have that in writing, I guess.
Unfortunately, the trampoline does not sit flat on the ground due to this. Given all my other responsibilities and the potential costs involved, I did not decide to further pursue an action against JumpKing at this time. However, as mentioned at the top of this, I am open to the idea because I can be sure that other consumers are getting ripped off by JumpKing as we speak.
