Installing the flush-mount in-ground 12x18 MAX model requires the largest excavation footprint of any rectangular trampoline we offer. Because of the sheer volume of displaced soil (~13.5+ cubic yards), proper water management is essential during installation.
You need a clear, flat lawn area measuring at least 18 feet by 24 feet to provide a safe perimeter around the trampoline.
The 12x18 features a single-jumper operational weight limit of 396 pounds with a static structural test capacity of 1,750 pounds.
The 12x18 MAX utilizes an engineered array of 142 total springs: 134 double-galvanized main 8.5-inch Power Springs™ plus 8 specialized 5.5-inch corner counter-springs that maintain uniform mat tension into the corners.
Yes, the 12x18 rectangle trampoline is available in a traditional above-ground format.
The 10x17 provides 170 square feet of canvas, whereas the 12x18 MAX delivers 216 square feet of canvas. The 12x18 is 2 feet wider and 1 foot longer, providing ~27% more jumping surface.
The 12x18 features an authentic Lifetime Frame Warranty, a 10-year warranty on springs, and 3-year coverage on both the jumping mat and safety padding.
While the 1,750-pound static capacity frame can easily support the weight of adults and kids, safety guidelines and product warranties always recommend one jumper at a time.
