The Complete Parent’s Guide to Trampoline Park Injuries in Sachse, Texas

“His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child.”

Those are the words of Kaitlin “Kati” Hill, a mother whose three-year-old son Colton suffered a broken femur and a grueling recovery in a body cast after a trampoline incident. Her warning has been shared hundreds of thousands of times because it taps into a primal fear shared by every parent in Sachse: the realization that a place advertised for “family fun” can, in a split second, become a place of permanent trauma.

At Attorney911, we know that what happened to Colton Hill—and what may have happened to your child in Sachse—was not a freak accident. It was the predictable output of a systemic failure. Whether the injury occurred at an Urban Air in the surrounding DFW area, a local backyard trampoline along Highway 78, or a community event in Woodbridge, the legal architecture remains the same.

We are not just a personal injury firm. We are a team led by Ralph Manginello, who brings over 25 years of courtroom experience and federal court admission to the Southern District of Texas. Our team include’s associate attorney Lupe Peña, who previously worked on the other side of the table—defending insurance companies and large recreational businesses. He knows their playbook because he helped write it. Now, he uses those insights to dismantle the very waivers and defense strategies that Sachse families are told are “ironclad.”

If your child is currently at a Level 1 pediatric trauma center like Children’s Medical Center Dallas or Cook Children’s after a bad landing, you need more than sympathy. You need an advocacy system built to take on the parent conglomerates behind these parks—companies like Sky Zone, Inc. (formerly CircusTrix) and Unleashed Brands (the parent of Urban Air).

We handle these cases on a contingency fee basis. You pay us nothing unless we win. We advance every cost—the biomechanical engineers, the pediatric orthopedic specialists, and the ASTM-compliance experts—because your child’s recovery fund should stay untouched.

Why a Trampoline Injury in Sachse is Never “Just an Accident”

When a child is hurt at a trampoline park serving the Sachse area, the manager or the insurance adjuster will often use the word “accident.” They want you to believe that the risk was inherent—that by signing a waiver at a kiosk, you accepted the possibility of a broken bone or a spinal cord injury.

We reject that premise. In our 25+ years of experience, we have found that nearly every catastrophic trampoline injury is the result of a business decision that prioritized margin over safety.

The Profit-Over-Safety Architecture

ASTM F2970 is the industry’s own safety standard for commercial trampoline courts. The industry—including chains like Sky Zone, Urban Air, and Altitude—wrote this standard themselves. They set the floor for what constitutes a safe environment. Yet, on a busy Saturday afternoon in the North Dallas suburbs, many parks knowingly operate below that floor.

They reduce attendant-to-jumper ratios to save on labor costs. They skip the weekly rotation of foam blocks in the pit because it takes the attraction out of service. They allow “Advanced Skills” like backflips to occur in open-jump zones because enforcing the rules ruins the “vibe” and potentially reduces repeat business.

When a 200-pound adult lands on a trampoline bed while an 80-pound child from Sachse is pushing off, physics takes over. That child’s launch force can be multiplied by up to four times, resulting in velocities that a child’s skeletal system is not designed to absorb. This is a known mechanism called the “double-bounce.” The park knows it. The standards address it. When the park fails to separate age groups or weights, they aren’t having an “accident.” They are accepting a known risk of a shattered femur or a crushed growth plate.

The National Authority, Local to Sachse

While we are based in Texas, following the $11.485 million Cosmic Jump verdict in Harris County—the largest reported jury verdict against a US commercial trampoline park—we have positioned ourselves as a nationwide authority on these cases. We know which waiver clauses in Texas will hold and which ones, like those that fail the “fair notice” or “express negligence” doctrine, are full of holes.

Our firm currently litigates a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure. The medical experts and discovery protocols we use in that complex litigation apply directly to the rhabdo and compartment syndrome cases we see in trampoline parks. We don’t just “handle” injury cases; we build architectures of accountability.

The 72-Hour Evidence Clock: Why Waiting is the Biggest Risk in Sachse

If your child was injured in a Sachse backyard or a neighboring city’s trampoline park, the clock is running against your case. This isn’t just about the two-year Texas statute of limitations under CPRC § 16.003. It’s about the evidence clock.

The DVR Overwrite Cycle

Most commercial trampoline park surveillance systems are set to overwrite footage within 7 to 30 days. Some systems purge even faster during high-traffic periods. The video of the attendant on his phone, the video of the multi-person bounce, and the video of the unmaintained equipment is being erased as you read this.

The “Revised” Incident Report

Parks often use digital incident-management systems. We have seen patterns where an original report, filled out by a witness the night of the injury, is “finalized” or revised 48 hours later to sanitize the language and shift blame onto the “guest error.” Metadata is the only way to prove a report was altered.

The Waiver Purge

Kiosk waiver databases often rotate version histories. If the park “updates” their waiver text post-injury to retrofit better conspicuousness, the version your family signed might become difficult to retrieve without forensic intervention.

Our spoliation letter goes out within 24 hours of your retention. We demand the preservation of the DVR, the original incident report metadata, and the specific equipment involved—whether that is a failed net anchor or a compacted foam block.

Dismantling the Waiver: Why You Still Have a Case in Sachse

The insurance adjuster’s first move is always to point to the waiver you signed at the kiosk. They want you to think that paper is a wall. In reality, it is often just noise.

One of our attorneys, Lupe Peña, used to defend these same companies. He knows that the waivers drafted by corporate counsel for Sky Zone, Inc. or Unleashed Brands are frequently vulnerable to multiple attack vectors.

1. The Gross Negligence Carve-Out

Texas law, following the landmark Moriel decision, does not permit a business to waive liability for gross negligence. If the park had actual awareness of an extreme risk—such as a torn slide or an undertrained monitor—and showed conscious indifference, the waiver is void. This is how the Cosmic Jump case in Houston reached an $11 million result despite a signed release.

2. The Munoz Rule: Parental Indemnity

In Texas, the case of Munoz v. II Jaz Inc. established that a parent generally cannot sign away a child’s own personal injury claim before the injury occurs. While the 2025 Cerna v. Pearland Urban Air ruling favored parks on technical arbitration “delegation” clauses, the underlying right of the minor to hold the negligent party accountable remains a core piece of Texas doctrine.

3. The Dresser Fair Notice Doctrine

For a waiver to even be considered for enforcement in Sachse or elsewhere in Texas, it must meet the Dresser standards of “express negligence” and “conspicuousness.” If the part where the park says “we aren’t responsible even for our own mistakes” isn’t in bold, highlighted, or clearly set apart, the waiver can be struck by a judge.

4. Signer Authority and Language Barriers

Many Sachse families bring extended relatives to the park. If a grandmother, aunt, or older sibling signed for the child, they may not have had the legal authority under Texas Family Code § 153.073 to bind that child. Furthermore, if the family’s primary language is Spanish and an English-only iPad was shoved at them with a command to “sign fast,” the Delfingen doctrine allows us to challenge the very formation of the contract.

Catastrophic Pediatric Injuries: The Medical Reality for Sachse Families

A trampoline fracture isn’t just a “broken bone.” In a developing child, it is a life-altering event. Because children’s bones are not yet fully ossified, they are pliable and contain growth plates (physes) that are structurally weaker than the surrounding ligaments.

Salter-Harris Fractures and Growth Plates

If your child suffered an injury to the growth plate—common in the tibia and femur after a double-bounce—they won’t just need a cast. They will need a decade of monitoring. A Salter-Harris Type II fracture at age nine can result in a limb-length discrepancy that doesn’t fully manifest until age fourteen. We retain pediatric orthopedic surgeons to project those future surgeries and the lifetime impact on your child’s gait and athletic ability.

SCIWORA: Spinal Injury without Radiological Abnormality

This is a pediatric-specific danger. A child can sustain a catastrophic spinal cord injury in a foam pit dive, and the initial CT scan in the ER may look normal. This is because the child’s spine is ligamentous enough to stretch and snap back, while the cord remains permanently damaged. Our firm understands the neurology of these cases. We know that a child who is told to “walk it off” after a neck strike is a child at risk of permanent paralysis.

The Rhabdo / Compartment Syndrome Bridge

Following the same medical logic we are using in our active $10 million UH hazing case, we look for signs of rhabdomyolysis in children who jump for extended sessions in heated DFW-area parks. If your child had “cola-colored” urine or muscle pain wildly out of proportion after a visit, we know they may have suffered acute kidney failure—a result of choices made by the park regarding hydration and jump-session limits.

Psychological Trauma

The “worst scream” isn’t just a sound. It’s a memory that produces pediatric PTSD. Children who were once active and social may become withdrawn, fearful of play, and experience academic regression. We document the full emotional toll on the Sachse family system, ensuring the recovery includes the mental health support your child will need for years.

Liable Parties in Your Sachse Trampoline Case

Most law firms name the local park and stop there. We go upstream. The money is almost always upstream.

• The Operator LLC: The local entity on the lease, often carrying only a $1M primary policy.
• The Franchisee: The business group that may own multiple locations across North Texas.
• The Franchisor: Entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings. They mandate the training manuals and ratios. If they failed to enforce their own standards, they are on the hook.
• The Parent Corporation & Private Equity Sponsor: We look at Sky Zone, Inc. and its owner Palladium Equity Partners, or Unleashed Brands and its owner Seidler Equity Partners. We have litigated against BP and Walmart; we are not intimidated by the corporate layers of private equity.
• The Equipment Manufacturer: Whether it’s a backyard Jumpking, Skywalker, or Springfree, or a commercial court manufactured by a vendor like UA Attractions LLC, we pursue product liability for design and manufacturing defects.

Our former insurance defense background means we know exactly how these layers try to point the finger at each other. We use that finger-pointing to secure the maximum recovery for our clients.

Frequently Asked Questions for Sachse Parents

Can I sue if I signed the waiver at the park?

Yes. As discussed above, the waiver is not the end of your case. In Texas, waivers cannot cover gross negligence, and they often fail the “fair notice” test. Most importantly, a parent’s signature often cannot bar a child’s own legal claim. We have seen multi-million dollar results like Cosmic Jump ($11.4M) won despite signed releases.

What if my child was injured on a neighbor’s trampoline in Sachse?

Texas follows the attractive nuisance doctrine. If a homeowner has a trampoline that is likely to attract children who may not realize the danger, the homeowner can be liable—even if the child was technically a trespasser. While Sachse homeowners’ insurance often excludes trampolines, we look for umbrellas or manufacturer defects that can provide a path to recovery.

How much is my child’s case worth?

Catastrophic cervical injuries can see eight-figure valuations because the life-care plan alone—the cost of future nursing, equipment, and medical revisions over a 70-year life expectancy—can exceed $15 million. A serious fracture with growth plate damage often anchors in the $500,000 to $2.5 million range. We never promise a number, but we use the same forensic economists who quantified the settlements the firm has won in previous multi-million dollar injury cases.

The park manager said it was my child’s fault. Does that matter?

No. This is a common tactic called the “Contributory Jumper Blame.” The park has a non-delegable duty to supervise and enforce safety rules. A child under seven is conclusively presumed incapable of negligence in many contexts, and the park cannot outsource its safety duty to the very children it was paid to supervise.
