Trampoline parks like Sky Zone, Urban Air, and Rockin' Jump cause thousands of serious injuries annually, including spinal fractures and paralysis. Navigate California liability waivers, child injury claims, equipment defects, and negligent supervision to recover compensation for trampoline park injuries.

Understaffing and poor training are common and provable
Common Trampoline Park Dangers
Foam pits with inadequate depth causing "bottoming out"
Multiple jumpers on single trampolines
Inadequate padding between trampolines
Worn or defective trampoline surfaces
Insufficient staff to monitor all areas
Failure to enforce safety rules consistently
Child Injury Note: Trampoline park injuries disproportionately affect children. In California, parents CANNOT waive a minor's right to sue. If your child was injured at a trampoline park, the waiver you signed does not prevent your child from recovering damages for the park's negligence.
Evidence Collection for Trampoline Park Injuries
Immediate Documentation
Scene Evidence
Photograph the specific trampoline or area where injury occurred
Document foam pit depth and condition
Photo padding condition and any gaps or worn areas
Witnesses: Obtain contact information from other guests who saw the incident
Video footage: Parks have extensive camera systems; demand preservation immediately
Other incidents: Search for news reports of prior injuries at the same location
Online reviews: Google and Yelp reviews may mention safety concerns
ASTM standards: Reference ASTM F2970 (trampoline park safety standard)
Industry guidelines: International Association of Trampoline Parks (IATP) safety standards
Medical Documentation
Emergency care: Go directly to ER; document that injury occurred at trampoline park
Imaging: X-rays, CT, MRI to document fractures and soft tissue injuries
Specialist referrals: Orthopedic, neurology, or spine specialist as appropriate
Physical therapy: Document rehabilitation needs and progress
Long-term prognosis: Obtain opinion on permanent impairment or limitations
Video Preservation: Trampoline parks typically have extensive video coverage but may overwrite footage within days. Send a written preservation demand immediately requiring the park to preserve all video footage, incident reports, staff schedules, training records, and equipment inspection logs.
California Legal Framework for Trampoline Park Injuries
Liability Waiver Limitations
Adult Waivers
Civil Code 1668: Cannot waive liability for own negligence
Gross negligence: Waivers never cover gross negligence or willful acts
Clarity required: Waiver language must be clear and unambiguous
Conspicuous: Terms must be brought to patron's attention
Limited to inherent risk: May only cover risks inherent to trampolining
Equipment standards: Requirements for padding, clearances, and foam pit depth
Training requirements: Staff training and certification standards
Evidence of negligence: Violations of ASTM standards can establish breach of duty
California Advantage: California's strong consumer protection laws, the invalidity of parental waivers for minors, and Civil Code 1668 make California one of the most favorable states for trampoline park injury claims. Parks cannot contract away their duty of reasonable care.

[Trampoline Park Name]
[Park Address]
[Franchisor Name, if applicable]
[Franchisor Address]
Re: Personal Injury Claim - Trampoline Park Negligence
Claimant: [Client Name] [and Minor Child Name, if applicable]
Incident Date: [Date]
Location: [Park Name and Address]
Incident Time: Approximately [Time]
Dear Claims Representative:
This firm represents [Client Name] [and his/her minor child, Child Name,] regarding serious injuries sustained on [Date] at your [Park Name] location.

FACTS OF THE INCIDENT
On [Date] at approximately [Time], [Claimant/Child's Name] was [describe activity - e.g., "jumping in the main trampoline area" or "using the foam pit"] at your facility. [Describe incident - e.g., "While jumping, another patron collided with [him/her] from behind, causing [him/her] to fall awkwardly and land on [his/her] neck" OR "While jumping into the foam pit, [he/she] 'bottomed out' and struck the hard surface beneath the inadequate foam padding."]
At the time of the incident, [describe conditions - e.g., "the area was overcrowded with multiple jumpers on single trampolines despite your posted rules prohibiting this" OR "no staff members were present in the immediate area to enforce safety rules or prevent collisions."]

- [Specific breach, e.g., "Failing to station staff to supervise the area where the injury occurred"]
- [Specific breach, e.g., "Failing to enforce the one-jumper-per-trampoline rule"]
- [Specific breach, e.g., "Allowing overcrowding beyond safe capacity"]
- [Specific breach, e.g., "Failing to provide adequate safety training to staff"]
[IF MINOR CHILD:]
PARENTAL WAIVER IS UNENFORCEABLE
We are aware that a liability waiver was signed on behalf of [Child's Name]. However, under California law, parents cannot waive a minor child's future negligence claims. See Hohe v. San Diego Unified School District (1990) 224 Cal.App.3d 1559. [Child's Name] retains full legal rights to pursue claims for your negligence regardless of any waiver signed by [his/her] parent.
[IF ADULT:]
WAIVER DOES NOT BAR NEGLIGENCE CLAIMS
While a liability waiver was signed, California Civil Code section 1668 voids contracts that purport to exempt parties from liability for their own negligence. Your waiver may limit claims for inherent risks of trampolining, but does not protect you from liability for [describe negligence - e.g., "inadequate supervision, equipment defects, or failure to enforce safety rules"].

[Claimant/Child's Name] sustained the following documented injuries:
- [Injury 1, e.g., "Cervical spine fracture at C5 requiring surgical stabilization"]
- [Injury 2, e.g., "Traumatic brain injury with persistent post-concussive symptoms"]
- [Injury 3, e.g., "Complete ACL tear requiring reconstructive surgery"]
- [Injury 4, e.g., "Comminuted ankle fracture requiring open reduction internal fixation"]
Current medical expenses total $[Amount], with an additional $[Amount] in anticipated future treatment including [future treatment needs]. [Claimant/guardian] has incurred lost wages of $[Amount] from work missed for [own recovery/caring for injured child].
DEMAND
Based on the severity of injuries and clear evidence of negligence, we demand the total sum of $[Amount] to resolve all claims. This figure accounts for:
- Past medical expenses: $[Amount]
- Future medical expenses: $[Amount]
- Lost wages/earning capacity: $[Amount]
- Pain, suffering, and emotional distress: $[Amount]
- [For child: Future impairment and loss of enjoyment of life: $[Amount]]
We expect a substantive response within thirty (30) days. If we cannot reach a reasonable settlement, we will file suit and pursue discovery into your staffing records, training protocols, equipment maintenance logs, prior incident reports, and ASTM F2970 compliance.

Frequently Asked Questions
Yes, in many cases. California Civil Code section 1668 voids contracts that release parties from liability for their own negligence or fraud. While waivers may limit claims for inherent risks of trampolining, they cannot protect parks from negligence such as defective equipment, inadequate supervision, overcrowding, or failure to enforce safety rules. Courts also scrutinize whether waivers were clear and conspicuous.
No. California courts have consistently held that parents cannot waive a minor child's future negligence claims. In Hohe v. San Diego Unified School District and subsequent cases, courts ruled that parental waivers of children's tort claims are unenforceable as against public policy. Your child retains the right to sue for trampoline park negligence.
The most common serious trampoline park injuries include spinal cord injuries and paralysis, traumatic brain injuries, cervical and lumbar fractures, ACL and other knee ligament tears, ankle and wrist fractures, and neck injuries. Studies show trampoline parks have significantly higher injury rates than home trampolines, with multiple jumpers and foam pits presenting particular dangers.
Potential defendants include the park owner/operator for negligent supervision and rule enforcement, the franchisee and franchisor if a franchise location, equipment manufacturers for defective trampolines or padding, maintenance contractors for inadequate repairs, and individual employees for specific negligent acts. Parks may also be liable for inadequate staff training.
Photograph the area where the injury occurred, document equipment condition and any defects, note staffing levels and whether rules were being enforced, save your waiver and receipt, obtain witness contact information, do not give recorded statements to park management, seek immediate medical attention documenting the injury location, and request any incident report the park creates.
For adults, California's statute of limitations is two years from the date of injury under Code of Civil Procedure section 335.1. For minors, the statute is tolled until they turn 18, giving them until age 20 to file. However, evidence should be preserved immediately, and consultation with an attorney should occur promptly while witnesses can still be located.
