Use outside this range may cause damage and may void the warranty. Do not over-tighten the tension straps during installation, as excessive force may damage the components and will void the warranty.
Warnings – Injury Do not use your LapStacker to secure items that could cause injury, such as sharp, hot or heavy objects. Over-tightening the LapStacker straps may cause loss of circulation, pressure injury, or damage to items being carried. Avoid contact with your LapStacker during transfers to prevent injury or damage. Avoid extended use, which may cause loss of circulation or pressure injury.
