Size: Size XXS. The Squease pressure vest calms like a hug. When the Squease vest is inflated, it becomes tighter. This creates a firm pressure on the upper body, similar to a hug. This is helpful for reducing stress and anxiety or managing sensory hypersensitivity and overload. Additionally, it promotes body awareness and concentration, and it aids in relaxation and falling asleep. The pressure can be easily adjusted with the hand pump – depending on how much deep pressure is appropriate for your body. Even when fully inflated, the pressure vest can be worn under clothing without being noticeable. Deep pressure therapy is used for individuals with: Autism Spectrum Disorder (ASD), Attention Deficit Disorder (ADD), Attention Deficit Hyperactivity Disorder (ADHD), Asperger Syndrome (AS), learning disabilities, individuals with sensory hypersensitivity, pervasive developmental disorders (PDD/PDD-NOS), proprioceptive dysfunctions, sensory integration disorders (SID), and sensory processing and perception disorders (SPD).
