This therapy swing is very strong and resistant. The double layered blend of spandex and nylon is soft but durable. The swing is made to accommodate up to 200 lbs. Less Stress, Less Meltdown & A Better Opportunity For Your Kid To Learn & Play. The secret that makes this swing so effective at teaching kids how to self-regulate their emotions is the magic of Vestibular Input. It’s a fancy way of saying the sensation of movement. Vestibular input calms your child in minutes and allows them to self-regulate their emotions for hours. This means better focus while in class, doing their homework, and during family activities.
