One bounce. One bad landing. One broken neck. That is all it takes for a family in Lake Jackson to find their lives permanently altered at an indoor trampoline park.
At a birthday party in a facility serving Lake Jackson, a seven-year-old comes off a court on a stretcher. His parent had signed the waiver at the kiosk twenty minutes earlier, believing the marketing that promised a safe environment for “toddler time.” Today, that child is in a trauma bay at a Level 1 pediatric center in the Houston metro area, and the facility manager is looking for a way to say the child “jumped wrong.”
We know that story because we have spent twenty-five years hearing it. If your child was hurt at a trampoline park or on a neighbor’s backyard equipment in Lake Jackson, you are likely feeling a crushing mix of terror, anger, and a deep, unearned sense of guilt. You might think the paper you signed at the front desk ended your case before it began.
We are here to tell you that the waiver is not the shield the park wants you to believe it is. In Texas, the law protects children, even when a business attempts to hide behind a piece of digital paper. We are The Manginello Law Firm—Attorney911—and for over two decades, Ralph Manginello has made corporate defendants pay for the consequences of choosing margin over human life.
From our home base in the Houston area, we have gone head-to-head with some of the largest corporations in the world, including BP after the Texas City refinery explosion. We are not intimidated by the parent conglomerates behind Sky Zone, Urban Air, or Altitude. We built our practice on holding institutional defendants accountable, and we have secured multi-million dollar settlements for victims of traumatic brain injuries and spinal cord trauma—the exact categories of injury these parks produce with devastating frequency.
What happened in Lake Jackson was not a “freak accident.” It was the predictable output of a business model that scales high-risk maneuvers to industrial throughput, often while ignoring the very safety standards the industry wrote for itself. While your child fights to recover, the park’s risk management team is already working to preserve the company’s bottom line. The surveillance video that shows exactly what happened is likely set to be overwritten in as little as 7 to 30 days.
Our managing partner, Ralph Manginello, has recovered millions for families who were told they had no case. We include on our team a former insurance defense attorney, Lupe Peña, who used to represent these exact types of recreational businesses. He knows the script the adjusters use because he helped write it. Now, he uses that knowledge to dismantle the park’s defenses before they can be raised.
If your child is in a hospital bed today, you don’t need a general practice lawyer. You need a Lake Jackson trampoline injury attorney who can cite ASTM F2970 from memory and who understands that a Salter-Harris growth plate fracture is not just a “broken bone”—it is a decade-long medical challenge.

The Lake Jackson Trampoline Risk: Saturated Markets and Unregulated Courts
Lake Jackson families live in one of the most saturated trampoline park corridors in the United States. Between the clusters of parks in Pearland, Sugar Land, and the broader Houston metro, thousands of children from the Brazosport area are airborne every single weekend. Each time a child walks onto a court at Urban Air, Sky Zone, or a regional operator like Cosmic Air or Jumping World, the operator assumes a specific legal duty under Texas premises liability law.
The problem for Lake Jackson parents is the regulatory vacuum in the state of Texas. Texas has no statewide trampoline park safety act. There is no mandatory state licensing, no mandatory injury reporting to the Texas Department of Insurance (TDI), and no state-led inspection regime for the trampoline decks themselves. While the TDI regulates “Class B” inflatable rides—like the bungee trampolines or indoor coasters you see at Urban Air—the core trampoline courts are statutorily excluded under Texas Occupations Code § 2151.002(1)(C)(iv).
This means that in Lake Jackson, the only thing standing between your child and a catastrophic landing is the park’s voluntary compliance with its own internal rules and the industry’s voluntary consensus standards.
Ralph Manginello and our legal team treat this regulatory gap as a centerpiece of our negligence arguments. When the state fails to regulate, the duty on the operator to follow industry best practices—specifically ASTM F2970—becomes the absolute floor of reasonable care. Attorney911’s founder has spent 25+ years proving that when a business chooses to operate in a “rule-free” environment, they bear a heightened responsibility to manage the predictable risks of their equipment.
In Harris County, which neighbors Lake Jackson, juries have shown they will not tolerate operators who ignore these duties. The landmark $11.485 million verdict against Cosmic Jump in Houston serves as the ultimate warning. In that case, a teenager fell through a torn slide onto a concrete floor. Even though a waiver had been signed, the jury found gross negligence. Ralph Manginello and our firm use these local precedents to show Lake Jackson families that a signed waiver is not a blank check for a park to be reckless.
The Physics of Failure: Why Lake Jackson Children Get Hurt
Trampoline injuries are driven by physics that most Lake Jackson parents never had explained to them at the kiosk. When we litigate these cases, we don’t just talk about “accidents.” We retain biomechanical engineers to model the energy transfer that occurred at the moment of impact.
The Double-Bounce: The Catapult Effect
The most common mechanism in Lake Jackson trampoline accidents is the “double-bounce.” This occurs when two people jump on the same bed, and the heavier jumper lands just as the lighter jumper (usually the child) is pushing off. The energy stored in the mat is transferred to the child, multiplying their launch force by up to four times.
Our firm identifies this as a failure of supervision. ASTM F2970-22 requires parks to operationalize age and weight separation. When a 200-pound adult jumps with a 60-pound child from Lake Jackson, the park is accepting a 14x increase in injury risk for that child. If the monitor on duty was on their phone or watching a different court, the park has breached its duty.
Foam Pit Compaction and Depth Failures
Foam pits in facilities serving Lake Jackson look like safe landing zones. In reality, they are often the most dangerous attraction in the building. As hundreds of jumpers land in the pit, the open-cell polyurethane cubes at the bottom compress. If the park fails to “fluff” or rotate the foam per ASTM cadence, a jumper who lands head-first can strike the hard floor beneath.
The tragedy of the Ty Thomasson case in Phoenix—where a 2’8″ deep foam pit resulted in a broken neck—is the reason the industry is slowly moving toward airbags. Our team knows that if a Lake Jackson park is still using a foam pit in 2026, they are using an outdated technology that carries a heightened duty of maintenance. We subpoena the rotation logs and the foam replacement receipts in every pit case we take.
The $10 Million Rhabdomyolysis Bridge
One of the most under-recognized risks for Lake Jackson jumpers is exertional rhabdomyolysis. This occurs when extended physical exertion—especially in a hot indoor environment without hydration—causes muscle tissue to break down and spill myoglobin into the bloodstream.
We currently litigate a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. The pathology and medical experts involved in that case are identical to what we see in “all-day jump” cases where kids from Lake Jackson become dangerously dehydrated. If your child has “cola-colored” urine or muscle pain that seems impossible a day after visiting a park, this is a medical emergency. Our firm knows how to document the CK (creatine kinase) levels and the renal failure markers to prove that the facility’s lack of hydration protocols was the cause.
The Liable Party Stack: We Go Beyond the Local LLC
When your child is hurt in Lake Jackson, the local park manager may tell you they are “just a small local business.” This is usually a tactic to discourage you from seeking the full value of your case. Behind that local Lake Jackson-area operator is a layered corporate structure designed to shield assets.
We deploy a five-layer defendant stack in our trampoline litigation:
- The Operator LLC: The entity that owns the specific location.
- The Franchisee: The group that may own multiple locations in the Houston/Lake Jackson area.
- The Franchisor: Corporate entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings.
- The Parent Corporation: Sky Zone, Inc. (formerly CircusTrix LLC), backed by Palladium Equity Partners, or Unleashed Brands, owned by Seidler Equity Partners.
- The Component Manufacturer: The company that built the defective net, padding, or frame weld that failed.
The Damion Collins v. Urban Air Overland Park case, which resulted in a $15.6 million arbitration award in 2023, proved that the franchisor cannot hide. The franchisor in that case absorbed 40% of the fault because they failed to implement safety changes across the chain. Attorney911’s associate attorney Lupe Peña used to defend these types of commercial entities; he knows where the additional insured endorsements hide in these franchise agreements. We follow the money until we find a policy that can cover the lifetime care costs of a catastrophic injury.
Dismantling the Lake Jackson Waiver Defense
If you are reading this in Lake Jackson, you likely signed a waiver. You might be fearful that your signature ended your rights. That fear is exactly what the insurance adjusters want you to feel. But in Texas, the waiver is often a speed bump, not a wall.
The “Munoz” Minor Rights Rule
Since 1993, the controlling rule in Texas from Munoz v. II Jaz Inc. is that a parent cannot pre-emptively waive a minor child’s personal injury claim against a commercial operator. The child’s right to seek compensation for their injuries exists independently of the parent’s signature. While the Texas Supreme Court’s 2025 Cerna v. Pearland Urban Air ruling makes arbitration more likely in some cases, it does not extinguish the claim itself.
The “Dresser” Fair Notice Attack
Texas law requires that a waiver be “conspicuous” and meet the “express negligence” doctrine. Under the Dresser Industries v. Page Petroleum precedent, a release must the word “negligence” prominently and in a way that catches a reasonable person’s attention. If the waiver you signed in Lake Jackson was buried in twenty screens of digital text or if the word “negligence” was not set apart in bold, contrasting type, the waiver may be legally void for everyone—adults and children alike.
Gross Negligence and the Cosmic Jump Legacy
No waiver in Texas can release a company from gross negligence. If we can prove the park had “subjective awareness of the risk” and showed “conscious indifference” through actions like ignoring a torn mat or understaffing a court, the waiver vanishes. This is how the Harris County jury at Cosmic Jump was able to award $6 million in punitive damages despite a signed release. Our founder, Ralph Manginello, has spent 25+ years identifying these “conscious indifference” triggers through aggressive discovery.
Evidence Preservation: The 72-Hour Rule for Lake Jackson Families
The moment a child is injured at a park serving Lake Jackson, the evidence begins to disappear. This is not a conspiracy; it is a feature of the industry. DVR systems overwrite. Staff turn over. Inspections are “updated.”
If you haven’t called an attorney yet, do these three things immediately:
- Do not speak to the adjuster. They will call you with a “friendly” tone, pretending to care about your child’s recovery. They are actually looking for you to admit your child was “horseplaying” or that you were “distracted.”
- Order a lockout. We send a formal litigation-hold letter (a spoliation demand) within 24 hours of being retained. We demand that the park freeze its surveillance footage, its maintenance logs, its attendant shift schedules, and its waiver kiosk metadata. If the park overwrites the video after receiving our letter, we move for an adverse inference instruction, which tells a Lake Jackson jury to assume the video would have proved the park was at fault.
- Document the “Rhabdo” risk. If your child was at a park in the Lake Jackson summer heat, the temperature inside the facility matters. Save any receipts for water or Gatorade you purchased, as this confirms the hydration timeline.
Our team includes digital forensics experts who can interrogate the NVR systems of these parks. We know that by Day 10, the Saturday afternoon your child was hurt may be gone from the hard drive. We file faster than that.
Catastrophic Pediatric Injuries: Why Specificity Matters
A Lake Jackson parent standing at their child’s bedside hears terms they never wanted to know: Salter-Harris, SCIWORA, DIFUS axonal injury. When we litigate these cases, we don’t just say your child has a “broken leg.” We use the medical specificity that forces an insurance carrier to respect the depth of the damage.
Growth Plate (Salter-Harris) Injuries
Children’s bones are still growing. A fracture through the physis (growth plate) at age eight might not look like a disaster on Day 1. But by the time your child is thirteen, that leg may be two inches shorter or growing at a crooked angle. These injuries require a lifetime of orthopedic monitoring. We retain pediatric orthopedic surgeons to project those costs over the next decade of your child’s development.
SCIWORA (Spinal Cord Injury Without Radiographic Abnormality)
This is a terrifying pediatric conditions. A child may land on their head at a park, and an initial CT scan in a Lake Jackson-area ER might look “normal.” But the child’s flexible spine can stretch, damaging the cord while the bones snap back into place. Hours later, the child loses feeling in their legs. Parks that don’t train monitors to stabilize kids after a neck-first landing are inviting permanent paralysis.
Developing Brain Impact
A concussion in a child from Lake Jackson is fundamentally different from a concussion in an adult. The pediatric brain is still forming the executive function pathways. A TBI sustained on a trampoline can lead to permanent academic regression and behavioral changes that only manifest six months later. We use pediatric neuropsychologists to establish the “before and after” of your child’s cognitive development.
The Lake Jackson Attorney911 Moat: Why We Are Different
There are thousands of personal injury lawyers in the Houston/Lake Jackson market. Most handle car wrecks. Very few have built a practice around the specific architecture of trampoline law.
Choose our firm because:
- We Have the Insider Playbook: Lupe Peña knows the defense tactics because he used to raise them. He knows which waiver clauses are “full of holes” under Texas case law.
- We Understand the Pathology: Our active $10 million UH hazing case means we have the nation’s leading rhabdomyolysis and acute kidney failure experts on speed dial.
- We Are Battle-Tested in Federal Court: Ralph Manginello is admitted to the Southern District of Texas and has decades of federal experience. High-value trampoline cases often involve out-of-state corporate parents, which can pull a case into federal court. We are ready for that move.
- We Take the Cases Others Reject: As client Donald Wilcox said: “One company said they would not accept my case. Then I got a call from Manginello… I got a call to come pick up this handsome check.” Trampoline cases are hard because of the waivers. We take them because we know how to beat the waivers.
Frequently Asked Questions for Lake Jackson Parents
Can I sue if I signed an electronic waiver on an iPad at the kiosk?
Yes. Electronic signatures at Lake Jackson-area parks are subject to the federal E-SIGN Act and the Texas Uniform Electronic Transactions Act. If there were system glitches, timeouts, or if the signature cannot be definitively tied to your ID and timestamp, the agreement may fail. Furthermore, the Dresser conspicuousness rules apply to digital screens just as they do to paper.
What if the Lake Jackson park tells me the surveillance video is “unavailable”?
“Unavailable” is not an excuse—it is often a signal of spoliation. In the Mathew Knight case in Georgia, the park’s video “glitched” on four cameras simultaneously at the exact moment of the injury. The jury awarded $3.5 million because they didn’t believe in coincidences. We demand the DVR hard drive and the access logs to see who touched the footage and when.
Is the “foam pit” safer than the “airbag”?
No. The medical consensus and the industry’s own migration patterns show that pressurized airbags provide more uniform deceleration. If a park serving Lake Jackson still uses a foam pit, we investigate the compaction of the foam. A foam pit that isn’t rotated is essentially a pile of bricks.
How much is my child’s trampoline injury case worth?
The value depends on the permanent impact. National industry data shows that catastrophic spinal cord injuries can reach $15 million in life-care planning costs alone. Individual cases in Texas, like Cosmic Jump, have hit the $11 million mark for gross negligence and TBI. Even “simple” fracture cases can range from $50,000 to $500,000 if they involve growth plates or surgical pins.
Should I let the park’s insurance company pay for my child’s immediate bills?
Wait. They may offer you a “Med-Pay” check of $3,000 or $5,000. It sounds helpful, but the back of that check or the signature required to get it often acts as a full release of all future claims. Never sign anything from an insurer until Ralph Manginello or our team has reviewed it.
How do I know if the supervisor at the park was negligent?
We look for the pattern. Was the monitor a sixteen-year-old with three hours of training? Were they assigned to watch sixty jumpers instead of the ASTM-recommended thirty-two? Were they on their phone? The Washington State L&I fined Sky Zone for overworking teenagers—if a park treats its own staff that way, it likely isn’t prioritizing your child’s safety.
Lake Jackson’s Choice: The Case Starts Today
If your family is dealing with a catastrophic trampoline injury in Lake Jackson, the most important thing to know is that the clock is not on your side. The DVR overwrites. The incident reports get “revised.” The attendant quit last Friday.
What happened to your child wasn’t just bad luck. It was the predictable output of a business that decided that Lake Jackson families would accept the risk of the trampoline without being told the truth about the danger. We exist to hold those businesses accountable.
Ralph Manginello and The Manginello Law Firm work on a contingency fee basis. You pay nothing unless we recover money for you. We advance every expense—the biomechanical engineer, the pediatric specialist, the ASTM auditor. Your child’s recovery fund stays intact.
Every minute the park delays a phone call, they are getting closer to overwriting the evidence. Stop the clock.
Call 1-888-ATTY-911. We answer twenty-four hours a day. Lupe Peña speaks Spanish natively and can talk to you directly about your rights.
Your child represented a margin target for the park. To us, they are family. Let’s start the fight for their future today.
