Saw these guys at a home show and the product looked great. I was able to dig the hole myself and get it all installed in a few days! Looks great and can’t wait for this crazy Utah snow to go away so my kiddos can enjoy! Recommend to everyone.

Have not installed the tramp yet but i can say the logistics and support from ordering the tramp are fantastic. I ordered online and within 5 minutes Shane had called me and asked all the right questions about color and delivery. Within 24 hours he had personally drove the entire kit out to my house and stayed for about 20 minutes to show me all the tips and tricks on how to set it up the right way for the best results. From what i have seen so far, the kit i ordered is made of very durable material and the set up is insanely simple. I would absolutely recomend this company to a friend! Will possibly be posting another review after it is installed and tested!

We love this tramp! It’s extremely durable and really good quality. I’m always worried about making a purchase like this and it not holding up. We had ours installed a couple years ago. I have 6 kids, they all play on it daily and aside from the normal fade caused by the sun you would think it was installed a week ago. Highly recommend this product if your wanting a ground level tramp.

Ken and Shane were quick to respond to needs and handle things professionally. I’ve had an inground trampoline for many years. No broken bones, no one ever fell off and the wind couldn’t blow it away. Plus the kit is super easy to put together and not too heavy.

Our landscaper recommended TrampKit and we've loved it. The build quality is great and it was a lot easier to install due to the panels already being attached to the trampoline poles.

I have had and installed two other inground trampolines in the past and nothing is as good as this. This was so easy to install and I was able to pack the dirt around the tramp without any problems. Plus this trampoline is more bouncy than the other ones I have tried. Its the best one I have had by FAR.

We run a design build landscape company. We have installed hundreds of trampoline pits as well as designed and installed our own. This product by far is superior than any other we have installed. Including the one we designed ourselves.

This is the best tramp kit on the market. It was extremely easy to install and does such a good job protecting the integrity of the hole. It's well worth the money for the longevity of the system. I don't worry about collapse or erosion at all

This is my first in ground trampoline and I couldn’t be happier! Correction, my kids couldn’t be happier! My youngest daughter jumped on it for four hours straight once it went in the ground. The price was right, and they literally dropped it off at my house one day after buying it. Customer service is top notch too! They wanted my landscaper to call so they could help with any questions he had for an easy assembly. It’s got good bounce and the lawnmower drives around it no problem. 100% recommend if you’re looking for an in ground tramp!

We absolutely love it! It's the best trampoline kit we've seen and we did a LOT of research. Customer service was 10/10! Perfect, smooth edging for the grass. So sturdy and fun for the kids. And the material looks nice and is forgiving when bouncing. When I do yardwork, I bounce on it as I come and go. Makes me smile every time. It's been amazing!

Works With Any Trampoline Shape Or Size

When we designed the TrampKit in-ground trampoline system we wanted families who already had a trampoline to be able to convert it to an in-ground trampoline.  The hardest part about installing your trampoline is going to be getting the hole dug.  Any landscaping company with a mini-excavator can have the hole dug in a couple of hours or if you're a hardcore DIY'er you can simply rent a machine and do it yourself.

Installation Instructions
