Beast Trampoline is a US brand selling rectangular and round outdoor trampolines, best known for its K9 10x17 Performance Rectangle (with a stated "no weight limit" rating), the Amazing Spider 14ft and 15ft round models, and a smaller 9x6ft mini rectangle.
The K9 features 9.5-inch piano wire springs, a heavy-duty rectangular frame, and a premium enclosure, positioned as a performance trampoline for tricks and athletic use.
Pricing typically falls in the upper-mid to premium range depending on model. Beast sells primarily through Amazon and its own site, with a smaller catalog and lower brand awareness than the larger US trampoline brands.
