Trampoline Park Injury Demand Letters

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.

Cervical/lumbar fractures Improper landing technique, foam pit injuries, collisions Park operator, inadequate training

Why Trampoline Park Cases Succeed

  • California voids negligence waivers (Civil Code 1668)
  • Parents cannot waive children's claims in California
  • High duty of care owed to paying recreational customers
  • Industry has documented history of preventable injuries
  • ASTM standards provide benchmark for reasonable care
  • 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.

Sample Trampoline Park Injury Demand Letter
[Date] Via Certified Mail and Email [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. We write to demand compensation for medical expenses, lost wages, and pain and suffering resulting from your negligent operation of the trampoline 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."] LIABILITY ANALYSIS As a commercial recreational facility, you owed [Claimant/Child's Name] a duty of reasonable care to: 1. Maintain equipment in safe operating condition 2. Provide adequate supervision to prevent foreseeable injuries 3. Enforce safety rules consistently 4. Train staff properly in safety protocols 5. Warn of hidden or non-obvious dangers 6. Comply with industry safety standards (ASTM F2970) You breached these duties by: - [Specific breach, e.g., "Failing to maintain adequate foam pit depth, causing 'bottoming out'"] - [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"].

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. PRESERVATION DEMAND Preserve all evidence related to this incident, including: - All video footage from all cameras for [Date] - Incident reports from [Date] and 12 months prior - Staff schedules and assignments for [Date] - Employee training records - Equipment inspection and maintenance logs - Foam pit depth measurements and specifications - Any internal communications regarding this incident or safety concerns Sincerely, [Attorney Name] Attorney for [Client Name] [and Minor Child Name] [Law Firm] [Address] [Phone] [Email] Enclosures: - Medical records and billing statements - Incident photographs - Waiver copy - Lost wage documentation
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.
