I couldn’t be happier with our Beast K9 Rectangle Trampoline. The bounce on this thing is absolutely huge—far better than any round trampoline we’ve owned. The rectangular design gives consistent lift, and it feels super responsive.

What really impressed me is how sturdy it is. The entire frame feels rock-solid, and the build quality is definitely premium. The piano-wire springs are a game changer—they give an unbelievably smooth, powerful bounce and feel much more durable than standard coil springs.

If you want a trampoline that’s heavy-duty, safe, and delivers insane performance, this is the one. Worth every penny!

Awesome product. Well worth the $$. Very heavy and strong. Should last a lifetime. Much more bounce than others we’ve tried. Kids love it. Company takes care of its customers. Would not hesitate to buy again.

This thing is epic and amazing! I love that there’s enough room for two kids to jump with plenty of space around them.
Took about four hours to put together toughest part was those first springs …you really really need two people for this! Also, an instructional video would have been amazing because a lot of time was wasted debating what the directions stated and we received two sets of directions that were slightly different. The spring pull tool broke on the second spring, which could’ve been really dangerous. Great trampoline though!

We left a google review but figured should leave one here as well. We have had the K9 for about 6 months now and so far the trampoline has been great. Kids love it and seem to really like the black springs and the assembly was easy with very little hardware. The zippers made connecting the enclosure feel like a dream :-)

Easy to assemble solo, high quality parts. The instructions could use a little more detail. For example I only realized there was a spring puller tool included after I was done. Otherwise, its a great Trampoline!

We are very pleased with the trampoline. The bounce is great and the whole family can jump together

Love these trampolines. Super good bounce, and tons of room. Really great for kids and adults.

We have owned several other trampolines and this has been by far the best!! Super solid and sturdy.. a Beast!! The design and quality of materials has obviously been very well thought out. I'm impressed with how well it handles multiple jumpers. Toddlers to parents, everyone loves it! A+ on the full experience; ordering, communications, delivery and set up.

This is our our first trampoline. After months of researching quality, cost and size, I came across Beast. I read the reviews on ALL the competitors to see what people said about pros and cons. I was sold on the K9 10x17.
It’s fun! It’s big. It’s not squeaky. It’s strong enough/tough enough to hold our very large family. It feels sturdy and safe, easy to assemble, well packaged, and customer service is A+.

I put this together with the help of 2 - 11 y/o boys. It was super easy. Kids absolutely LOVE it!
